This is exactly how to respond to criticism. Let go of your ego, put science and studies behind it, and find the best way to do something and share it with everyone. You're the best Jeff.
It's crazy though if you apply science to other areas of life nowadays it doesn't seem to matter as much. Feelings and opinions seem to trump the science and facts
@bluejay2623 It depends, in the medical field, science and fact are respected. In politics it's thrown out the window. When it comes to fitness feeling I prioritized. Some people still think creatine is 100% placebo to every single person.
Support those doing studies for sure but remember one study does not = fact and another study could be done that shows completely different results. Take those single studies as bits of evidence to put toward the bigger pile you sort out to form your own opinion, and always be open to changing it if/when evidence supports it.
@@TyaColono....? Those studies are then peer reviewed by people smarter than you who point out all the flaws and the infomation is expanded from there It isn't a fact it becomes theory which is practically a fact Your opinion going againts a peer reviewed study is wrong because the peer reviewed study is right. There can be different studies with different bases, but that will always be right....its like saying "form your own opinion on gravity" There can be advancements that change building however this proof will still have better results we can learn something that says a 4th method is better but that dosnt disprove that of the 3 this one is better Biology won't change since this is in the context of the other 3 as long as a study is proven testes and peer reviewed it's as close to a fact as possible A theory can be expanded apon but not disproven unless you littrally disproven the entire baseline to biology
@@diveblock2058 Everything you said is true and I agree, but my counter is this: Literally doesn’t matter how sure you are a single study or an entire body of work is “fact”, if you’re following the scientific method and using critical thinking you will more than likely come to the same conclusion on your own, and your conclusion will change when appropriate evidence arrives. Thus imo we’re much better off preaching constant and never ending skepticism and open-minded thinking than trying to insist one thing is right. The fact of the matter is as much evidence we have in favor of the theory of gravity at some point we could (or could not) find new contradictory evidence that forces the scientific community to rethink what is “fact”. And if you preach to everyone how gravity is an undebatable fact, then new evidence arises, the general public, not understanding the scientific method, will call you a hypocrite and further distrust science. Look at the pandemic to see that exact principle at work.
200% of 0 = 0… love you really Jeff and you did not need to respond to the haters at all, let alone smash them out the park with this. Thanks for the great content Jeff
So you’re telling me someone doing a full ROM on a flat barbell bench press, chest to bar, won’t see significantly more growth, than someone doing partial reps, half the distance that the bar travels? I call BS.
It was so funny to hear Dr. Wolf, Dr. Pak, Dr. Helms, and then Dr. Mike all come on one after another. Talk about a dream team! So this is the study they've been talking about for months on the podcasts! I think this is most valuable to know if you struggle with maintaining form through the whole range of motion, or have a weird injury or something that makes doing it at the shortened length feel wrong. I'm thinking specifically about lateral raises in my case; my upper traps try to help when they shouldn't if I try to do the full ROM at heavier weights. If I can only go 75% of the way and get the same benefit, then that's awesome.
@@mfrebel7831 What do you mean by not finishing? That you don’t hit a certain rep range? If that’s the case, lower the weight until you’re within your target range and only raise it when you move outside of that range consistently
Jeff is my favorite lifting influencer on UA-cam. Not only is he natty and still impressively big, but he puts a ton of effort to put good info into his vids and make them look great. He’s also very humble
Love the approach and the fact that the results where not necessarily going 100% in the direction you "wanted" is a big plus in terms of credibility on your side. Good job guys.
So I'll just keep doing partials after I can't do full ROM reps anymore, like I've done for years at the point. No harm, no foul, takes balls to make and release a video like this, hats off to all who made this possible.
definitely agree that this is the best of both worlds! biggest (in both senses of the word lmao) person i can think of who does this in their own training is GVS, and his effort levels and physique certainly speak for themselves lmao. starting with full ROM and then doing lengthened partials to failure literally lets you have your cake and eat it too
@@yannini11 The conclusion I took from this is that lengthened partials is another addition to the volume/intensity balance where the two variables each add growth but at the cost of recovery. A blanket statement that you should always finish your sets with lengthened partials does not take into account the recovery cost of doing those which is arguably the most important variable. Your training should be adapted to train just hard enough to allow you to recover and currently most people who train hard probably are already at this point and adding lengthened partials will not add significantly more stimulus but will add enough recovery cost to push them over that boundary. Tl;dr: Since this doesn't add anything significant the same principles as before still apply. Manipulate volume and intensity to keep you recovered and ready for the next session without also leaving a lot in the tank. Lengthened partials can be a variable to add but doing so would necessitate that you remove volume or intensity elsewhere.
In my opinion the best recipe is this: - full ROM - deep stretch (with slight pause) - slow negative - lengthened partials on the last 2-3 reps when full ROM can no longer be achieved
Agreed. Even if focusing on full stretch doesn't add more muscle, being strong in the bottom, full stretch makes lifting safer. People hurt themselves on bench or preacher curls cause they dont train to fullnstretch and lift out of it.
If you would read his referenced studies, you'd see how similar most of that science based lifting is to r/science. Take some (in part poorly done) studys, misrepresent their results and hope people only bother to read at most the headlines. For example he linkes study "Training in the Initial Range of Motion Promotes Greater Muscle Adaptations Than at Final in the Arm Curl". If you read the study, you'll see in the result section, that partial lengthened reps only significantly increase CSA at 70% distal length, but not overall CSA. Same goes for the new "study". The results show no significant difference, but they go on to claim that the reason for that, is that full ROM is just an extended partial rep. (By the way they can't even show no difference to a significant level, because the design was poor).
@@robertmusil1107Did you not absorb anything you just watched? The study was focused on full range of motion compared to stretched partials, and they were equal. Meaning you get the same exact gains from doing half of the rep in the stretched portion of the lift. Meaning that the stretched portion of the lift is where you are building your muscle.
You have no idea how much your videos have helped me mentally and physically. I was at a really low point in my life, but I started locking in, and your videos helped me a lot. Thank you so much!
what a concise, scientifically-sound, calm response to the call-outs. inspirational as a lifter and as a human who can take criticism and respond like an adult, a rarity nowadays, jeff is what a person should strive to be.
This is the SOOOO Jeff to respond to hate with a personally funded study that specifically focuses on the points his critics were using to diminish the studies he was citing.
The 2 biggest questions after seeing this: 1. How did you take into consideration the “crossover effect” when accounting for differences? We know that with individuals who injure a limb that often times doing exercises with the healthy/functioning side or limb results in a noticeable effect on compensation through adaption with the other. So, with this study we understand that the idea was to balance out the groups by splitting left vs right sides in case you had someone genetically gifted, but we realize that because of the crossover effect variable, your data was potentially skewed towards the null outcome. This explains why the before mentioned studies testing separate groups on full ROM vs lengthened partials had larger variances. Knowing the physiological effects of the crossover effect, I think this explains the almost null outcome and further evaluation is needed. I still think the “only lengthened partials” group is onto something, we just need more of those studies to achieve an accurate conclusion. 2. While not as important from a hypertrophic standpoint (which I believe was the primary goal of this particular experiment in the video) I am extremely interested on the effects of tendon/ligament strengthening. For instance, while I might get the same muscle-building benefits from lengthened partials vs full ROM, what about my tendon strength? As an example, most would advise to drop weight on preacher curls and focus on full ROM because a major concern would be a breakage of the bicep tendon. The same could be said for a squat, leg extension, pulldown, etc. I realize that the lengthened partials already work the most vulnerable/effective position for hypertrophy, but would there be more protection and benefit to the overall strength of the human body to prevent injury and increase mobility by doing full ROM? I’m extremely interested because if lengthened partials vs full ROM end up having the same outcome for hypertrophy, but there is a significant increase in overall tendon strength and mobility with full ROM, then overall, full ROM would be superior.
I really wouldn’t consider the crossover effect at all. It isn’t supported by any data and, even among its claims, it’s mostly a strength based transference with little to no mention of hypertrophy, which is what this study is testing. On point 2, tendon/ligament strength is just not a very well understood concept. Period. We barely understand it mechanically, and we have no idea to the extent or ability. Here I’m getting a bit out of my depth so don’t repeat anything here as fact, but tendon/ligament injury is just not a massive concern or even point of improvement for natural lifters. If your tendons or ligaments break, it’s at their ATTACH points, not the bellies, and there’s really nothing you can do about that, period. Your tendons and ligaments also just aren’t prone to long term injury. Most of what people experience as “tendon pain” is actually a joint misalignment/pain causing an inflammation in the tendons, not a weakness of the tendon itself. Again, not something you can particularly “train” against, other than treating whatever imbalance is causing the problem. You aren’t going to fix patellar maltracking by strengthening your knee cap ligaments. Unless you have a degenerative disorder, your only risk of injuring a ligament or tendon is hyperflexion, working out cold, or lifting beyond your means. Thats where preacher curls become a problem, people tend to hyperflex on them.
Good questions. I just watched the Will Tennyson + Magnus videos and Magnus (as a pro climber) does a ton of both, but obviously lots more fully stretched movements. He was pound for pound stronger than Will in almost every metric except shoulder press I think? So yeah for sports I think full range movements are the essential movements to avoid injury and keep your entire body strong.
@@arunkarthikma3121 the only difference between partial group and full ROM group was the range of motion. Everything else was equal including controlling the eccentric, slight pause and explosive concentric. Therefore we can say that the lifters made equal gains with lengethened partials as compared to full ROM in less time.
@@TurdBoi666 Yep - unfortunately not many lifters know about experimental science - so they think one set of results "proves" that result. This is despite all of the science-based guys on UA-cam repeatedly explaining why many studies looking at exactly the same hypothesis are needed.
I wanted to put this here so hopefully you’ll see it as I’d be interested in your opinion. Thanks BRO! I think one aspect that has been overlooked/not mentioned was the fact that they went to failure. This is significant since it affects how many reps people do for partials and full ROM. Since the work being done for each rep is less for partials than full ROM, the subjects will end up doing more partials than full rom. However, when you look at time under stretch/resistance for both treatments, there would be an insignificant difference. This has gotten me thinking, maybe the reason that stretched positions may increase muscle gains is because your muscles act almost like a rubber band under tension when stretched. They hold some of the energy in and this in turn gives you a small boost when initially applying force. What does this mean? It means you essentially cheat the system and save energy. This saved energy means you can output more total work for your muscle which results in slightly more muscle development. Just some food for thought.
A book that changed my life in ways that I never could imagine is "Secret Testosterone Nexus of Evolution".Drop whatever you're doing right now and go find that book. Trust me after I implemented things from the book my testosterone levels went beast mode
I agree, it's great, and the core of science in general. People often misinterpret science as this definitive dogma, when really science is based on the continuous evolution of collective knowledge in a way that controls for as many variables as possible.
IMO a big point people miss is that the main reason talking about the stretch is SO important is because most lifters I see in the gym ,if they are making any mistakes, its that they avoid the lengthened portion of most lifts because its harder! So whether you are using Full ROM or lengthened partials, both are a vast improvement over half repping in the shortened position by cutting depth on movements like squats, bench, curls, etc. Keep spreading the good word Jeff. You’re the man!
I agree, the reason it's important is to know about this is that if you are going to go partial go lengthened partial instead of chasing the squeeze, i.e. in biceps, and to suck it up and take the pain of going for the stretch.
Absolutetly. Even some of those critizising are actuall not doing full range often and precisely skip the lengthen portion. Is not just the people in my opinion, but also the fact that some classical exercises themselves (how they were designed) as well as some machines promote skipping this part of the range, and this should serve as a reason to get rid of those exercises/machines.
100% agree with this comment. Whether or not “lengthened partials” are superior to full ROM or “worth programming” is up to the individual. But without question this proves that the muscle is built during the stretch portion of the movement.
@@Jensen_Gamingthere are exercises we ALL know Work well that Never reach the most stretched positon. Like the ohp and the regular bench press. I Wonder If the mid position Works as well as the most stretched position.
@marketlider2811 that is just not true. Maybe the way some people do the bench press, leaving the bar 5 CMS away from the chest, as I do folks do in the gym constantly, yes. If you do a proper bench press with your back arched (add an irregular bar for extra stretch) you are definitely hitting the stretch positions. As for the OHP not sure I guess you are meaning chest, well, not the best exercise to train chest. Do some proper dips instead and let me know how sore you are feeling next day.
Simple: do a combination of both. Start with full range and then add lengthen partials when needed. I’ve done this with rest pause sets and cluster sets and worked wonders. The key is controlling the intensity and volume when doing lengthen partials on certain exercises (ex. Lengthen partials on a leg press vs preacher curl)
Thanks for going through the effort to carry out this experiment Jeff. I've made a video about "1.5 reps" on my channel, integrating full rom + lengthened partials for the best of both worlds (size & strength) Keep up the good work mate
The length of the motion has almost nothing to do with strength/size. You determine those with volumen of reps and rest times. This video literally just proven that full ROM and LLP are exactly the same for hypertrophy
John Meadows program , has been incorporating Full Rom and Partials reps for ages even before these studies. Hes a legend indeed. Way ahead of his time. RIP MountainDog
This video officially crowns Jeff Nippard as the GOAT fitness YTer. He is humble enough to listen to his critics. He doesn’t make a wild reaction video screaming and ranting into the camera to defend himself and in turn exposes his insecurities. Instead, in his typical Jeff Nippard’s neutral tone, he made an entire video purely to seek for the objective truth nothing else, risking having egg on his face in front of all of his viewers. And when the actual results came out, he could have sugar-coated the video or not post the video altogether. But he didn’t. His dedication to educating the masses of real fitness knowledge for purely the benefit of his viewers is unmatched. We did not just watch a fitness video. We watched how to take criticism and react like a real human being should. God bless this man.
its mostly genetics to start with. all they talk about is a minimum of 5% increase of anything, after doing a "correct" excercise. the rest is influencer bullshit to sell your channel .
How can you hate this man He is extremely serious in his job and genuinely wants the best for the fitness industry and is READY to let go of his ego and being unbaised in his tests 😅 Truly the face of natural and scientific bodybuilding
@@hayden4988 should I expand on what I mean? Idk if I feel like getting into a comments battle right now. I’ll say this and then leave. Yeah obviously I know I can do what I want in the gym. I have other reasons for saying it shined lifting.
Having Coach Greg yelling in my sleep is the fuel of night mares!! I fully appreciate Jeff's approach, not calling people out, not saying others are idiots, he just gets in does the research produces the information and facts. Love it... What about full ROM until you hit close to failure and the lengthened partials until complete failure?
Jeff's one of the few guys I still follow on youtube. Levelled takes, good science, and doesn't have another youtube channel with weird AF philosophy like a certain other influencer.
"Participants were instructed not to perform any additional upper-body RT (resistance training) outside of the study protocol but were permitted to perform lower-body RT and other physical activities at their discretion." In case anyone else was wondering.
@@familyonly2164dude the video literally stated that to get rid of such confounding factors, each individual used one side of their body as the control (full ROM). when there is a within-sample control it literally does not matter whether they decided to do full marathons or sit at home and watch youtube.
I have switched my focus to the stretch portion of the lifts and the difference was rapid and very clear to me personally. Milk the stretch is the way to go.
As a beginner lifter myself, it changed my results drastically, probably due to the 'sarcomeres in series' effect (an area I was lacking due to sarcopenia/shortening from extreme sedentary lifestyle) Reality: MOST people watching this stuff are in the 'average/beginner' category. Relatively few are advanced lifters. The benefit to those who need it most, vastly outweighs any 'overhype' negative effect to already trained lifters.
@@HJDfWrawRWRwathanks doc for your incredibly well thought out opinion! I’m sure you were watching bro day and night and were able to come to that conclusion!
I definitely also made some huge improvements starting to focus on the stretch but also on full range of motion. I got very quick visible results even though I was training for 4 years when I started to pay attention to it. But two years later I would say that yes there was a visible and quick improvement but it slowed down pretty quickly as well.
Jeff is what I strive to be. Not physically, but a man of craft and passion. He truly loves and is fascinated by the art and science of body building, it's why I love him. I gravitated to him initially bc I am also a short guy, but as time has gone on, his value has greatly exceeded that. Keep being you jeff, I wouldn't want it any other way.
@@FridgemaxxedHybridoreanL-wi6rg I think he's just pointing out that he meant this particular admiration that he is referring to is an admiration of character, despite his impressive physique or indifferent to it.
I'm more of a subscriber to Boogs' methodology for lifting, but will always respect Jeff for stuff like this. Honest and open minded. Even if Jeff was wrong, so what if he is willing to set aside his ego to showcase a study that benefits everyone's lifting. Mad props for doing this.
Jeff, I love your attention to detail and not getting lost in the weeds! As a registered nurse and working through injuries and many patient's with inferior/superior limb injuries, the control set by the same person is still receiving the centrally nervous system stimulation. First hand, I had a rotator cuff repair in November of 2023. Attempting to become as lopsided as possible went from bicep at 16.25" to 13.5" within 2 weeks (grrr bicep muscle fibers lose the quickest). Whenever you have a person with a knee or upper extremity injury, I always recommend getting the other side as strong as possible to facilitate a quicker recovery. I dig the information and have detailed training logs with rep/set count information for the past year. The variable of CNS stimulation may be an interesting underlying variable to take into consideration...Thanks again!
This has to be appreciated. Not only did Jeff actually fund and oversee a study just to update his knowledge (and by extension, ours too), but also he didn't shy away from sharing the results even when it wasn't emphatically in favor of what he's been saying all along Props to you man! Your videos are helping a newbie lifter like me improve in heaps Could you clarify just one thing though? Were the participants in the study doing the same reps in partials as full ROMs in the sets that weren't till failure? Or were all sets to failure? Because I think we can get away with more reps if we do partials so that might also be a contributing factor to improving gains in lengthened partials Edit: apparently a lot of people are not able to understand what I'm trying to ask. I'm asking how many reps on average did the participants do in partials and full ROMs. Since Jeff has made another video where he talks about lower reps can provide more hypertrophy, so that might be an advantage for full ROMs since you can do more reps on partials
stop citing sources that just came out with few studies. look at the research that has been done for a long time. u can find sources and cite "science" on just about anything u want to. citing "science" that hasnt been researched well enough and making a video of it and call it ground breaking is just click bait
Man I am a normal guy and I really like your channel. You and Dr. Mike have so much content and leading information on how to train and be better during out workouts that is helping me A LOT. The part of the connection with the muscle, focusing on controlling the work out and progress every day, day after day is starting to show smalls results and I’m really proud of myself. Thanks for sharing tour knowledge with us and help us improve. Cheers from Brazil 💚
As someone who teaches the interpretation and application of research in medicine, I greatly appreciate what Jeff has done here. The only thing I would have liked to have seen is an additional comparison with shortened partials (i.e. only focusing on the squeeze). As it stands, if lengthened partials and full ROM have statistically equivalent gains, that might suggest that it's just the stretch that's relevant. But that finding would also be consistent with it not mattering if one focuses on only the stretch, only the squeeze, or focusing equally on both. Obviously, there's a limitation that people only have 2 actual physical arms for the 2 figurative arms of a study in which they serve as their own control, so logistically, this would have required at least doubling the sample size.
I don't think he bothered to do that because the studies that have already been done show a significant downside to "shortened" partials. Both full ROM and lengthened partials come out way ahead
I used to watch Jeff when I first started at the gym several years ago. Came back for the first time in years, fuck me he is killing it. Millions of views every video wow. Congrats
I’ve been working out for a few years now listening to you primarily. When I tell you ITS THE MF STRETCH that has made this year of training for me truly amazing and fulfilling. So thank you
Honestly, this is why we subscribe. In contrast to Greg Doucette's "science, science, science [is dumb]", your cerebral take is why you are one of the best fitness UA-camrs on this platform. You are one thoughtful dude, and we appreciate it.
I don’t think Jeff gets enough credit for how incredibly good he is at video production. I would watch his videos no matter what they are about just because they’re so pleasing to the eye.
Ehhh he wasn’t really wrong. The fact that you can get the same gains means that (based on this data) lengthened partials are by far the most important component of a lift
@@MegaFunnyvids4u1problem is shortened partials would probably have been similar. We’ve known for years training simply isn’t usually the limiting factor for hypertrophy.
Jeff is the light to my darkness. The girth to my length. The glaze to my donut. The cream to my crops. The fertiliser to my seed. He brings out the best in everyone!
I haven’t watched this video yet, but what i will say is that i’ve been working out for over 2 years now, and i was at a 6 month plateau. I broke that plateau after incorporating a lot of Jeff’s advice, and now im stronger than i’ve ever been. No matter if people think he doesn’t know what he’s talking about (which i’m pretty sure he does,” he helped me get bigger and that’s proof he did something right
@tobbele1010 @nadanadie12 @xboxgamer120120 a lot of it had to do with emphasizing the stretch, like he said. I incorporated a lot of exercises that really stretched the muscle, most of which I got from his tier list videos. For example, I watched one of his videos that talked about doing an angled dumbbell lateral raise, and so far my delts have been way bigger. I also started doing incline/flat cable flies for chest, behind the back cable curls, belt assisted calf raises, and a ton of others. Another thing that he helped me with was form. I learned that leaning back on quad extensions, and leaning forward on hamstring curls really stretch the muscles, which got my squat up from 225lbs to 365lbs for reps. Also, his behind the back cable kickbacks and EZ bar overhead triceps extensions have really grown my triceps. My overhead triceps extensions went from 80-90lbs to 120-130lbs for reps. Overall, he's really helped me not only get bigger, but get way stronger.
I'm relieved by the result. In my experience it all comes down to simplicity (find good exercise, push yourself, chart your results, exceed previous achievement) and anything that complicates your mindset is distraction. Now I can just get on with working out without worrying about the minutiae.
I did lengthened partial past full ROM failure before all these studies 😆 I think the issue some people are having with science-based fitness is that it takes away some people's focus from going and doing their own science in the gym lab, just getting good at LIFTING you know, good at building muscle. It's a skill and science can be used for that but you'll find the best answers to what works for you by experimenting and applying yourself in the gym. It shouldn't be exclusive but as trainer and coach, I've seen many people overthinking "science" before even being a consistent gym goer. Great work on the video and study still ofc 🙏
I love this mindset, instead of feeling the need to apologize when almost the whole fitness influencer community called him out saying he was wrong, he didnt step back and proved his point with his own study
I don't know the kind of fitness community you are following, I haven't seen a single guy saying anything negative about the lengthened partials. Maybe I'm in a bubble, I don't know, but listening to guys like Greg Doucette = disrespecting your own time and energy.
@@arturzinurov2146 What are the "more benefits" you're referring to? According to this study, and others, doing only lengthened partials vs. full ROM accomplish virtually the same thing.
@@arturzinurov2146 The study found no significant evidence of a huge disproportion in muscles growth and given that the range of error of the study is around 0.8% and that you can do more lenghtened partials than full motions It really doesnt make a difference. I prefer training with full motions Max stretch but the study did not prove him wrong
I've been lifting for almost 20 years since I was a teenager, and my chest has NEVER grown much despite all the different exercises out there, and despite strength increases in all aspects of upper body parameters. 6 months ago, I tried dips for the first time, along with paused push ups (bring sally up/down routine), putting emphasis on the stretched position. My chest has grown more over the past 6 months with just bodyweight training, than the past 20 years of weight training/powerlifting.
It's called pseudo science, Jeff made up some "science" bs just to make content. Lifting ain't that complicated, it's quite simple, but if the influencers said that, they would run out of content. So they make goofy pseudo science bs up. And y'all eat it up. Get off the couch and you will see how easy it is to build muscle
@@kingiam9271 Jeff literally did whole scientific study, explained how he did everything, and you still called it pseudo science? You're not the smartest one, are you?
@@ShoomLa and the conclusion was there is no difference. I could of told you that. Next he will conduct a scientific study on wether working out at 9am is better than working out at 10am 😒🤦 let me save you the time. It doesn't matter. Yet you will be amazed at the results 🤣
@kingjam9271 I never understood this perspective. Jeff wants to double check something we might all intuitively know as true, and then when he does, it turns out we were all right. Why are you upset with someone who simply double checked? You are saying it's a waste of time, but Jeff clearly didn't think so. Who are you to tell Jeff how to live his life? It's not bullshit, he literally just decided to observe something one time...
Great video as always. I’d also like a study where after full ROM, the subjects do lengthened partials vs just stopping, and see how much of a difference there is.
Love the dedication to actually perform a study. It would be really cool to see how the effect of lengthened partials changes over time, i.e at what point in lifting does the difference between lengthened partials and full rom become negligible (if it even does)
I discovered Jeff in 2018. I was a fan since then and followed all his scientific based programs in muscle building. Though some influencers based result, I rather focus on the right pattern of exercise that I was making and that's why I subscribed to him. Following his program for me is a safety net ensuring the progress that I made and safe execution in each exercise so I will not injure myself and make the best workout that I can make for myself. You're the man, Jeff.
Full ROM contains the lengthened partial portion. I think this study actually supports the hypothesis that lengthened partials portion is the main portion responsible for the majority of muscle growth.
I think the intent of the study was direct comparison. Full range of motion is the baseline, so you have to use it. I think this study shows clear evidence that the lengthened partial is the business end of the lift, so now they need to find a way to compare net time under tension, which could mean higher volume, same fatigue in LP.
To many folks out there who talk out of the arse because they pull their talking points out from the snow channel. I have been lifting for close to 30 years and after listening to Jeff's advice about incorporating the stretch element in the lift I have found amazing results! especially at my age of 47 and I can't do the type of workouts I used to do when i was in my 20s and 30s since my joints aren't just what they used to be.. Thanks Jeff for doing the homework and letting the rest of us borrow your notes!
This was such an insightful experiment! It's fascinating to see that lengthened partials can be just as effective as full range of motion. Definitely going to incorporate more of this into my training. Great work and thanks for backing it up with solid research! 💪🔥
It's definitely still very impactful to our idea of how best to train overall. Like people have mentioned, a combination of the two methods could result in much greater gains. I can train an exercise with full ROM for say 10 reps before I can't do another full rep, and then switch to lengthened partials and get a few more reps. More volume, essentially more gains. Another thought, because you may be able to do more weight with a lengthened partial, you could use this as a progression scheme. Lateral raises come to mind immediately as going from the 20lb to 25lb dumbbells is a huge jump. Instead, I could do partials until I can do full ROM and then increase the weight. Reset back to partials, and so on. In the long term, this may result in greater gains purely because the lifter can continue to progressively overload in a more straight forward manner.
Doing more volume doesn't equal more gains, you just want to maximize mechanical tension(last 5 reps to failure) and minimize fatigue. And for the progression scheme thing, just use a more stable exercise that you can overload like a human. Cable lateral raise or even chest supported dumbel lateral raise is a milion times more stable and u can overload the exercise far easier
The thing I've taken from lengthened partials is you can take full ROM to within 1 of failure, then crank out a few more with a lengthened partial to potentially get a lit a bit more out of it.
Love that despite all the contrarians, Jeff Nippard still continues what he does best. He went ahead and further expanded the studies trying to understand what's going on. Data wins overall. You may "feel" or "think" something is a certain way but knowing for certain what is and what is not will always yield what you expect. Appreciate your hard work and dedication! 💪
our focus on the importance of the stretched part of a lift is a refreshing perspective that challenges conventional wisdom. I found your discussion on the study design particularly insightful. By using a within-subjects approach, you effectively control for genetic variability, which is often overlooked in fitness research. This method not only strengthens the validity of your findings but also provides a clearer picture of how different training modalities impact muscle growth. Additionally, I think it’s crucial to highlight the practical applications of your findings for everyday lifters. Many people may not realize that incorporating lengthened partials can enhance their training results, especially for those who may struggle with full range of motion due to mobility issues. I’m excited to see the results of your study and how they might influence the broader fitness community. Keep pushing the boundaries of our understanding in training science!
I have been lifting since I was 12. I'm 32 now. I'm 5'6 and my max bench was 350 (weighing 158lbs, natural). A big part of lifting, for me, has been understanding that it's just not that complicated. Do what works for you, to an extent. ROM is important and improves your physique. I am completely content where I am at naturally. Being 5'6, the extra lbs make a difference. So, I lift to maintain. I don't go crazy anymore. I workout 30-40 mins max. There's no need to be in the gym for 2-3 hours.
@@MobikSaysStuff Good, the thing about the right is.....We are right. 90% of men who lift are right wing. I think you ment "Mike turned out to be even more of a legend when we found out he is on the right"
As a new viewer of your content, I heard someone say that unlike other fitness influencers it truly feels like youre trying to help everyone. That alone was enough to make check you out!
It would be interesting to see a study where : One group does full range of motion and, Other group does full range of motion until failure then continues length partials until failure
@@alastairkennett7794 Yes, but if you usually train using both arms with barbells, pullup bars, etc, your dominant arm might be doing slightly more work. So when you then train them separately one might expect the less developed arm to grow slightly more.
@@BeavisGoFIREFIREFIRE like how would you set the weights in first place, right? I always work both sides at the same time and i set the weight to be hard enough for the weaker hand so it would definitely be easier for my right arm (good one) to lift, if i did them separately
You cant have higher increases because of muscle dominance that is in any way significant if you have people who been lifting for 5 years. Its not like they've been lifting with one arm exclusively so the other now sees newbie gains. But regardless, the simple solution would be to have half of them work left-full ROM, right LLP, and the other half left LLP, right full ROM
I agree with Sam saying "Go fucking hard". But if I am going to annihilate myself at the gym, I would like to squeeze every last bit of gains out of it as I can. I think a lot of people who repeat this mentality are more focused on the feeling of having completed a difficult workout than actual growth
One thing I feel like the anti-stretch/lengthened partial crowd doesn’t acknowledge is that performing an exercise in that way can sometimes cut out excessive fatigue. They’ll say “well, see, no statistical difference so just do full reps”, but if you cut out the squeeze part of the movement on something like a fly or lat pulldown I’d wager you’re cutting out a lot of fatigue as well. Both intra-workout, and accumulative over a training block, meaning there’s potential to perform more sets, accrue more stimulus, and still adequately recover.
I totally disagree. The lengthened position is way more fatiguing relative to contraction based exercises. Preacher curls are better than spider curls, but you can do way more sets of spider curls.
the lengthened part of a lift is the most damaging portion of the lift so you're actually completely wrong. And no muscles don't grow from "micro-tears"
@@sebbiesydenham3077 If I was talking only about producing more physical damage to the muscle, I would agree. But I was mostly talking in terms of nervous system fatigue. Like going psycho mode on the last few reps of the pulldown insisting on having the bar touch your chest on every rep. Personally, I find that it’s there where I get the most fatigued, and if I cut that part out I’m able to go harder and feel better on the subsequent sets than if I spent a lot of energy on that squeeze portion of the rep.
@@symphinx you’re wrong again. If you’re matching RIR then the systemic fatigue will be the same. The only difference is muscle fatigue from LLP is greater than full Rom. More muscle damage, more fatigue, longer recovery time. All of that for no added hypertrophy benefit. LLP are literally a pointless concept being pushed by PHD holders for clicks online.
Honestly ive been working out for a year and then decided to give more attention to the form, the range of motion, controlling the negative AND choosing exercises focusing on a deep stretch and holding it for about 2 seconds. And my gains skyrocketed. I aint saying this is the holy grail, but i changed something in my trainingstyle and something changed in my gains... thats just what im sayin 🤷♂️
Full ROM or Partials? Why not both? Full ROM in the beginning and then take your set to failure with partials at the stretched portion of the lift. Beauty Vid Jeff!
@@savonmies8479 dont do it every set with every exercise obviously. Should depend on what body part is your focus at that time or how rested you are etc.
I dont think you arę wrong. Im consistent with your advices and IT all works very well. I can safely say that my last 6 month progress was all thanks to you.
Got two questions: 1) Were the results the same when using the dominant vs non-dominant side? 2) When using LLP, it feels a bit easier to carry the weight. So you can either increase the weight and do the same amount of reps as in the Full ROM or you can increase the reps with the same weight. Was that taken into account? Been using your full body program for 6mo and gained 10kg so far. Big fan of your work
Jeff makes it seem like partials are just easier and give the same results, but like you said but you'd have to do more weight or more reps, which doesn't sound any easier than just doing full rom. And also, more weight means more wear and tear on your bones and tendons, which take way longer to heal than muscles do.
The big takeaway for me: doesn't really matter whether you do full ROM or lengthened partials. You basically can't go wrong with either one. As long as you avoid shortened partials you're good.
That and actually workout/manage recovery well. I know it sounds counter productive/intuitive, but some people enjoy working out in what would be suboptimal ways. They make up for it with consistency and work ethic. If you aren't paid to be an athlete I feel like all the nuance of what is optimal and what isn't really isn't something everyone needs to overly worry about.
This is exactly how to respond to criticism. Let go of your ego, put science and studies behind it, and find the best way to do something and share it with everyone. You're the best Jeff.
This! Jeff is pretty humble and listens to others. I dig the dude
It's crazy though if you apply science to other areas of life nowadays it doesn't seem to matter as much. Feelings and opinions seem to trump the science and facts
@bluejay2623 It depends, in the medical field, science and fact are respected. In politics it's thrown out the window. When it comes to fitness feeling I prioritized. Some people still think creatine is 100% placebo to every single person.

Dude is so dedicated he funded an actual study to know how to train best
Support those doing studies for sure but remember one study does not = fact and another study could be done that shows completely different results. Take those single studies as bits of evidence to put toward the bigger pile you sort out to form your own opinion, and always be open to changing it if/when evidence supports it.
For size, nothing more. That only serves an esthetic purpose, not a practical one.
@@TyaColono....? Those studies are then peer reviewed by people smarter than you who point out all the flaws and the infomation is expanded from there
It isn't a fact it becomes theory which is practically a fact
Your opinion going againts a peer reviewed study is wrong because the peer reviewed study is right. There can be different studies with different bases, but that will always be right....its like saying "form your own opinion on gravity"
There can be advancements that change building however this proof will still have better results we can learn something that says a 4th method is better but that dosnt disprove that of the 3 this one is better
Biology won't change since this is in the context of the other 3 as long as a study is proven testes and peer reviewed it's as close to a fact as possible
A theory can be expanded apon but not disproven unless you littrally disproven the entire baseline to biology
@@diveblock2058 Everything you said is true and I agree, but my counter is this: Literally doesn’t matter how sure you are a single study or an entire body of work is “fact”, if you’re following the scientific method and using critical thinking you will more than likely come to the same conclusion on your own, and your conclusion will change when appropriate evidence arrives.
Thus imo we’re much better off preaching constant and never ending skepticism and open-minded thinking than trying to insist one thing is right. The fact of the matter is as much evidence we have in favor of the theory of gravity at some point we could (or could not) find new contradictory evidence that forces the scientific community to rethink what is “fact”. And if you preach to everyone how gravity is an undebatable fact, then new evidence arises, the general public, not understanding the scientific method, will call you a hypocrite and further distrust science. Look at the pandemic to see that exact principle at work.
And it was a waste of resources, who would have guessed
Muscle growth with full ROM: 6.6% increase
Muscle growth w lengthened partials: 5.9% increase
My respect for Jeff: 200% increase
200% of 0 = 0… love you really Jeff and you did not need to respond to the haters at all, let alone smash them out the park with this.
Thanks for the great content Jeff
@@liama2846so was he right about the stretch or not?
@WizzlyBearW0rms well jeff does talk about stretching alot 😏
doesn't that increase on both methods seem little high for trained individuals tho? 5-6% in a year is nuts let alone 2 months,
So you’re telling me someone doing a full ROM on a flat barbell bench press, chest to bar, won’t see significantly more growth, than someone doing partial reps, half the distance that the bar travels?
I call BS.
It was so funny to hear Dr. Wolf, Dr. Pak, Dr. Helms, and then Dr. Mike all come on one after another. Talk about a dream team! So this is the study they've been talking about for months on the podcasts!
I think this is most valuable to know if you struggle with maintaining form through the whole range of motion, or have a weird injury or something that makes doing it at the shortened length feel wrong. I'm thinking specifically about lateral raises in my case; my upper traps try to help when they shouldn't if I try to do the full ROM at heavier weights. If I can only go 75% of the way and get the same benefit, then that's awesome.

Love the approach and the fact that the results where not necessarily going 100% in the direction you "wanted" is a big plus in terms of credibility on your side. Good job guys.
Results not being as hoped or "expected" is an incredibly flawed way to think about trust/credibility.
@@Generic_Name_1-1 yeah, the results were not what he expected, and he still posted it, he could have just not.
So I'll just keep doing partials after I can't do full ROM reps anymore, like I've done for years at the point. No harm, no foul, takes balls to make and release a video like this, hats off to all who made this possible.
I'm wondering why this is not the conclusion Jeff took. It seems like the perfect combination.
I follow one of his training programs and this is exactly what he recommends when lifting heavy for low reps
Try do partials when squatting 6 plates or RDL'ing 7 then?
definitely agree that this is the best of both worlds! biggest (in both senses of the word lmao) person i can think of who does this in their own training is GVS, and his effort levels and physique certainly speak for themselves lmao. starting with full ROM and then doing lengthened partials to failure literally lets you have your cake and eat it too
@@yannini11 The conclusion I took from this is that lengthened partials is another addition to the volume/intensity balance where the two variables each add growth but at the cost of recovery. A blanket statement that you should always finish your sets with lengthened partials does not take into account the recovery cost of doing those which is arguably the most important variable. Your training should be adapted to train just hard enough to allow you to recover and currently most people who train hard probably are already at this point and adding lengthened partials will not add significantly more stimulus but will add enough recovery cost to push them over that boundary.
Tl;dr: Since this doesn't add anything significant the same principles as before still apply. Manipulate volume and intensity to keep you recovered and ready for the next session without also leaving a lot in the tank.
Lengthened partials can be a variable to add but doing so would necessitate that you remove volume or intensity elsewhere.
In my opinion the best recipe is this:
- full ROM
- deep stretch (with slight pause)
- slow negative
- lengthened partials on the last 2-3 reps when full ROM can no longer be achieved
R u small be honest
This is the way
Agreed. Even if focusing on full stretch doesn't add more muscle, being strong in the bottom, full stretch makes lifting safer. People hurt themselves on bench or preacher curls cause they dont train to fullnstretch and lift out of it.
@@danielboard4471 bro you need to relax, I'm definitely bigger than you and i agree with him.
does your recipe also include increased muscle damage and calcium ion fatigue?

But yeah, great video Jeff!!
Yeah and it turned out the shittalkers were right.
@@robertmusil1107yeah you didn’t really watch the video. They were pretty much the same
If you would read his referenced studies, you'd see how similar most of that science based lifting is to r/science. Take some (in part poorly done) studys, misrepresent their results and hope people only bother to read at most the headlines.
For example he linkes study "Training in the Initial Range of Motion Promotes Greater Muscle Adaptations Than at Final in the Arm Curl". If you read the study, you'll see in the result section, that partial lengthened reps only significantly increase CSA at 70% distal length, but not overall CSA.
Same goes for the new "study". The results show no significant difference, but they go on to claim that the reason for that, is that full ROM is just an extended partial rep. (By the way they can't even show no difference to a significant level, because the design was poor).
@@robertmusil1107Did you not absorb anything you just watched?
The study was focused on full range of motion compared to stretched partials, and they were equal. Meaning you get the same exact gains from doing half of the rep in the stretched portion of the lift. Meaning that the stretched portion of the lift is where you are building your muscle.
You have no idea how much your videos have helped me mentally and physically. I was at a really low point in my life, but I started locking in, and your videos helped me a lot. Thank you so much!

Thought the same! Also its fun to do that way
Spot on !!
My thought process as well. You can finish your working set, and continue to push a bit past failure by doing a few lengthened partials reps.
@@SSSauceyBuns oh my God, beautiful beautiful way of training, i do that too.
true bro, everybody wants maximal fatigue with minimal gains, truly good choice
The 2 biggest questions after seeing this:
1. How did you take into consideration the “crossover effect” when accounting for differences? We know that with individuals who injure a limb that often times doing exercises with the healthy/functioning side or limb results in a noticeable effect on compensation through adaption with the other. So, with this study we understand that the idea was to balance out the groups by splitting left vs right sides in case you had someone genetically gifted, but we realize that because of the crossover effect variable, your data was potentially skewed towards the null outcome. This explains why the before mentioned studies testing separate groups on full ROM vs lengthened partials had larger variances. Knowing the physiological effects of the crossover effect, I think this explains the almost null outcome and further evaluation is needed. I still think the “only lengthened partials” group is onto something, we just need more of those studies to achieve an accurate conclusion.
2. While not as important from a hypertrophic standpoint (which I believe was the primary goal of this particular experiment in the video) I am extremely interested on the effects of tendon/ligament strengthening. For instance, while I might get the same muscle-building benefits from lengthened partials vs full ROM, what about my tendon strength? As an example, most would advise to drop weight on preacher curls and focus on full ROM because a major concern would be a breakage of the bicep tendon. The same could be said for a squat, leg extension, pulldown, etc. I realize that the lengthened partials already work the most vulnerable/effective position for hypertrophy, but would there be more protection and benefit to the overall strength of the human body to prevent injury and increase mobility by doing full ROM? I’m extremely interested because if lengthened partials vs full ROM end up having the same outcome for hypertrophy, but there is a significant increase in overall tendon strength and mobility with full ROM, then overall, full ROM would be superior.
ah, my question, just asked better two weeks ago!
I really wouldn’t consider the crossover effect at all. It isn’t supported by any data and, even among its claims, it’s mostly a strength based transference with little to no mention of hypertrophy, which is what this study is testing.
On point 2, tendon/ligament strength is just not a very well understood concept. Period. We barely understand it mechanically, and we have no idea to the extent or ability.
Here I’m getting a bit out of my depth so don’t repeat anything here as fact, but tendon/ligament injury is just not a massive concern or even point of improvement for natural lifters. If your tendons or ligaments break, it’s at their ATTACH points, not the bellies, and there’s really nothing you can do about that, period. Your tendons and ligaments also just aren’t prone to long term injury. Most of what people experience as “tendon pain” is actually a joint misalignment/pain causing an inflammation in the tendons, not a weakness of the tendon itself. Again, not something you can particularly “train” against, other than treating whatever imbalance is causing the problem. You aren’t going to fix patellar maltracking by strengthening your knee cap ligaments. Unless you have a degenerative disorder, your only risk of injuring a ligament or tendon is hyperflexion, working out cold, or lifting beyond your means. Thats where preacher curls become a problem, people tend to hyperflex on them.
Good questions. I just watched the Will Tennyson + Magnus videos and Magnus (as a pro climber) does a ton of both, but obviously lots more fully stretched movements. He was pound for pound stronger than Will in almost every metric except shoulder press I think? So yeah for sports I think full range movements are the essential movements to avoid injury and keep your entire body strong.

Yeah, my only concern is the duration of the reps, did the partial group hold the rep for half the time? Equal time?
@@arunkarthikma3121 the only difference between partial group and full ROM group was the range of motion. Everything else was equal including controlling the eccentric, slight pause and explosive concentric. Therefore we can say that the lifters made equal gains with lengethened partials as compared to full ROM in less time.
@@TurdBoi666 Yep - unfortunately not many lifters know about experimental science - so they think one set of results "proves" that result. This is despite all of the science-based guys on UA-cam repeatedly explaining why many studies looking at exactly the same hypothesis are needed.
Pleasure working on this study king 🙏🏻 thank you so much for your help. Detailed breakdown of the study on my channel!
So happy to see you rapidly growing. Keep striving and stay strong 💪
I wanted to put this here so hopefully you’ll see it as I’d be interested in your opinion. Thanks BRO!
I think one aspect that has been overlooked/not mentioned was the fact that they went to failure. This is significant since it affects how many reps people do for partials and full ROM. Since the work being done for each rep is less for partials than full ROM, the subjects will end up doing more partials than full rom. However, when you look at time under stretch/resistance for both treatments, there would be an insignificant difference. This has gotten me thinking, maybe the reason that stretched positions may increase muscle gains is because your muscles act almost like a rubber band under tension when stretched. They hold some of the energy in and this in turn gives you a small boost when initially applying force. What does this mean? It means you essentially cheat the system and save energy. This saved energy means you can output more total work for your muscle which results in slightly more muscle development. Just some food for thought.
Would you frame the results as: "Full ROM works BECAUSE it includes the lengthened/stretched position"?

I agree, it's great, and the core of science in general. People often misinterpret science as this definitive dogma, when really science is based on the continuous evolution of collective knowledge in a way that controls for as many variables as possible.
That is the scientific method after all and so as a scientific lifter this is actually to be expected. Lots of respect for his method.
Why the fuck would he lie
My favorite thing about Jeff is his mic set up. Being able to hear how C R E A M Y the inside of his mouth is during every video is incredible!
IMO a big point people miss is that the main reason talking about the stretch is SO important is because most lifters I see in the gym ,if they are making any mistakes, its that they avoid the lengthened portion of most lifts because its harder! So whether you are using Full ROM or lengthened partials, both are a vast improvement over half repping in the shortened position by cutting depth on movements like squats, bench, curls, etc. Keep spreading the good word Jeff. You’re the man!
I agree, the reason it's important is to know about this is that if you are going to go partial go lengthened partial instead of chasing the squeeze, i.e. in biceps, and to suck it up and take the pain of going for the stretch.
Absolutetly. Even some of those critizising are actuall not doing full range often and precisely skip the lengthen portion. Is not just the people in my opinion, but also the fact that some classical exercises themselves (how they were designed) as well as some machines promote skipping this part of the range, and this should serve as a reason to get rid of those exercises/machines.
100% agree with this comment. Whether or not “lengthened partials” are superior to full ROM or “worth programming” is up to the individual. But without question this proves that the muscle is built during the stretch portion of the movement.
@@Jensen_Gamingthere are exercises we ALL know Work well that Never reach the most stretched positon. Like the ohp and the regular bench press. I Wonder If the mid position Works as well as the most stretched position.
@marketlider2811 that is just not true. Maybe the way some people do the bench press, leaving the bar 5 CMS away from the chest, as I do folks do in the gym constantly, yes. If you do a proper bench press with your back arched (add an irregular bar for extra stretch) you are definitely hitting the stretch positions. As for the OHP not sure I guess you are meaning chest, well, not the best exercise to train chest. Do some proper dips instead and let me know how sore you are feeling next day.

@@meatsauce12 no he's not the money isn't coming out of his pockets, if you wanna be a smart ass at least be correct
Simple: do a combination of both. Start with full range and then add lengthen partials when needed. I’ve done this with rest pause sets and cluster sets and worked wonders. The key is controlling the intensity and volume when doing lengthen partials on certain exercises (ex. Lengthen partials on a leg press vs preacher curl)
Thanks for going through the effort to carry out this experiment Jeff.

If someone had done lots of cardio during these 8 weeks that can affect muscle growth.
But in the end the statistical difference is insignificant
@@familyonly2164dude the video literally stated that to get rid of such confounding factors, each individual used one side of their body as the control (full ROM). when there is a within-sample control it literally does not matter whether they decided to do full marathons or sit at home and watch youtube.

People can still eat whatever they want as long as they show results. You're being quite shallow Steve
It's also a zero sugar mtn dew.
I have switched my focus to the stretch portion of the lifts and the difference was rapid and very clear to me personally. Milk the stretch is the way to go.
No, you just ate and rested better.
As a beginner lifter myself, it changed my results drastically, probably due to the 'sarcomeres in series' effect (an area I was lacking due to sarcopenia/shortening from extreme sedentary lifestyle)
Reality: MOST people watching this stuff are in the 'average/beginner' category. Relatively few are advanced lifters.
The benefit to those who need it most, vastly outweighs any 'overhype' negative effect to already trained lifters.

@@HJDfWrawRWRwathanks doc for your incredibly well thought out opinion! I’m sure you were watching bro day and night and were able to come to that conclusion!
I definitely also made some huge improvements starting to focus on the stretch but also on full range of motion. I got very quick visible results even though I was training for 4 years when I started to pay attention to it. But two years later I would say that yes there was a visible and quick improvement but it slowed down pretty quickly as well.
Jeff is what I strive to be. Not physically, but a man of craft and passion. He truly loves and is fascinated by the art and science of body building, it's why I love him. I gravitated to him initially bc I am also a short guy, but as time has gone on, his value has greatly exceeded that.

Jeff, I love your attention to detail and not getting lost in the weeds! As a registered nurse and working through injuries and many patient's with inferior/superior limb injuries, the control set by the same person is still receiving the centrally nervous system stimulation. First hand, I had a rotator cuff repair in November of 2023. Attempting to become as lopsided as possible went from bicep at 16.25" to 13.5" within 2 weeks (grrr bicep muscle fibers lose the quickest). Whenever you have a person with a knee or upper extremity injury, I always recommend getting the other side as strong as possible to facilitate a quicker recovery. I dig the information and have detailed training logs with rep/set count information for the past year. The variable of CNS stimulation may be an interesting underlying variable to take into consideration...Thanks again!
This has to be appreciated. Not only did Jeff actually fund and oversee a study just to update his knowledge (and by extension, ours too), but also he didn't shy away from sharing the results even when it wasn't emphatically in favor of what he's been saying all along
Props to you man! Your videos are helping a newbie lifter like me improve in heaps
Could you clarify just one thing though? Were the participants in the study doing the same reps in partials as full ROMs in the sets that weren't till failure? Or were all sets to failure?
Because I think we can get away with more reps if we do partials so that might also be a contributing factor to improving gains in lengthened partials
Edit: apparently a lot of people are not able to understand what I'm trying to ask. I'm asking how many reps on average did the participants do in partials and full ROMs.
Since Jeff has made another video where he talks about lower reps can provide more hypertrophy, so that might be an advantage for full ROMs since you can do more reps on partials
Exactly.. ridiculous to leave such part out. I mean you can use much bigger weights on lenghtened partials
I assume from what he said that both groups were doing to failure.
Both were going to failure, he said so
@@Ism0Lait3laHe said they were both going to failure genius
stop citing sources that just came out with few studies. look at the research that has been done for a long time. u can find sources and cite "science" on just about anything u want to. citing "science" that hasnt been researched well enough and making a video of it and call it ground breaking is just click bait

This community is very fortunate too have y'all
You have no idea how many people appreciate that you point blank just conducted a study on it. That is the correct answer to every argument 👍🏾👍🏾👍🏾
As someone who teaches the interpretation and application of research in medicine, I greatly appreciate what Jeff has done here. The only thing I would have liked to have seen is an additional comparison with shortened partials (i.e. only focusing on the squeeze). As it stands, if lengthened partials and full ROM have statistically equivalent gains, that might suggest that it's just the stretch that's relevant. But that finding would also be consistent with it not mattering if one focuses on only the stretch, only the squeeze, or focusing equally on both. Obviously, there's a limitation that people only have 2 actual physical arms for the 2 figurative arms of a study in which they serve as their own control, so logistically, this would have required at least doubling the sample size.
I don't think he bothered to do that because the studies that have already been done show a significant downside to "shortened" partials. Both full ROM and lengthened partials come out way ahead
@@wredmatic Thanks for pointing that out. Do you know if those studies used beginner or experienced lifters?
@@StrongMed that's a good question; I don't know. But probably new lifters
shortened partials are out of the conversation and to run all three programs at the same time you would need six limbed lifters

The Lengthen Partials at the last few reps when I hit fatigue!! (Try to keep my form right) I think that’d be a good study
Jeff is the goat of the fitness industry fr. Creating your own study is the only real way to prove or disprove a point like this. Mad respect.

It doesn't matter if you 're wrong. A humble man can accomplish more. Great video.
Ehhh he wasn’t really wrong. The fact that you can get the same gains means that (based on this data) lengthened partials are by far the most important component of a lift
@@MegaFunnyvids4u1problem is shortened partials would probably have been similar. We’ve known for years training simply isn’t usually the limiting factor for hypertrophy.

I haven’t watched this video yet, but what i will say is that i’ve been working out for over 2 years now, and i was at a 6 month plateau. I broke that plateau after incorporating a lot of Jeff’s advice, and now im stronger than i’ve ever been. No matter if people think he doesn’t know what he’s talking about (which i’m pretty sure he does,” he helped me get bigger and that’s proof he did something right
What advise specifically?
Could you please share these advices?
Which tips did you follow to break the plateau?
@tobbele1010 @nadanadie12 @xboxgamer120120 a lot of it had to do with emphasizing the stretch, like he said. I incorporated a lot of exercises that really stretched the muscle, most of which I got from his tier list videos. For example, I watched one of his videos that talked about doing an angled dumbbell lateral raise, and so far my delts have been way bigger. I also started doing incline/flat cable flies for chest, behind the back cable curls, belt assisted calf raises, and a ton of others. Another thing that he helped me with was form. I learned that leaning back on quad extensions, and leaning forward on hamstring curls really stretch the muscles, which got my squat up from 225lbs to 365lbs for reps. Also, his behind the back cable kickbacks and EZ bar overhead triceps extensions have really grown my triceps. My overhead triceps extensions went from 80-90lbs to 120-130lbs for reps. Overall, he's really helped me not only get bigger, but get way stronger.
Lol post physique
I'm relieved by the result. In my experience it all comes down to simplicity (find good exercise, push yourself, chart your results, exceed previous achievement) and anything that complicates your mindset is distraction. Now I can just get on with working out without worrying about the minutiae.
I did lengthened partial past full ROM failure before all these studies 😆 I think the issue some people are having with science-based fitness is that it takes away some people's focus from going and doing their own science in the gym lab, just getting good at LIFTING you know, good at building muscle. It's a skill and science can be used for that but you'll find the best answers to what works for you by experimenting and applying yourself in the gym. It shouldn't be exclusive but as trainer and coach, I've seen many people overthinking "science" before even being a consistent gym goer. Great work on the video and study still ofc 🙏
Yeah some people switch up their entire workout routine because of one study and stop thinking for themselves
The edits is so smooth, loved it!
I love this mindset, instead of feeling the need to apologize when almost the whole fitness influencer community called him out saying he was wrong, he didnt step back and proved his point with his own study
I mean he proved nothing tho, full rom gives you more benefits on top of giving similar gains
I don't know the kind of fitness community you are following, I haven't seen a single guy saying anything negative about the lengthened partials. Maybe I'm in a bubble, I don't know, but listening to guys like Greg Doucette = disrespecting your own time and energy.
@@arturzinurov2146more benefits but similar gains? Bro read that sentence slowly. There isn’t any benefit over either that isn’t individual
@@arturzinurov2146 What are the "more benefits" you're referring to? According to this study, and others, doing only lengthened partials vs. full ROM accomplish virtually the same thing.
@@arturzinurov2146 The study found no significant evidence of a huge disproportion in muscles growth and given that the range of error of the study is around 0.8% and that you can do more lenghtened partials than full motions It really doesnt make a difference.

2:28 this is such a well done visualisation of the muscles just for this tiny part of background footage. props to the Editor.
I've been lifting for almost 20 years since I was a teenager, and my chest has NEVER grown much despite all the different exercises out there, and despite strength increases in all aspects of upper body parameters.
6 months ago, I tried dips for the first time, along with paused push ups (bring sally up/down routine), putting emphasis on the stretched position.
My chest has grown more over the past 6 months with just bodyweight training, than the past 20 years of weight training/powerlifting.
You gotta give Jeff credit for challenging his own beliefs and putting them to the test
It's called pseudo science, Jeff made up some "science" bs just to make content. Lifting ain't that complicated, it's quite simple, but if the influencers said that, they would run out of content. So they make goofy pseudo science bs up. And y'all eat it up. Get off the couch and you will see how easy it is to build muscle
@@kingiam9271 Jeff literally did whole scientific study, explained how he did everything, and you still called it pseudo science? You're not the smartest one, are you?

😂😂😂@@kingiam9271
@kingjam9271 I never understood this perspective. Jeff wants to double check something we might all intuitively know as true, and then when he does, it turns out we were all right. Why are you upset with someone who simply double checked? You are saying it's a waste of time, but Jeff clearly didn't think so. Who are you to tell Jeff how to live his life? It's not bullshit, he literally just decided to observe something one time...
Great video as always. I’d also like a study where after full ROM, the subjects do lengthened partials vs just stopping, and see how much of a difference there is.
Yeah, that's what I do, so it would be an interesting study on whether LPs are better or worse or the same as doing a drop set.
Love the dedication to actually perform a study. It would be really cool to see how the effect of lengthened partials changes over time, i.e at what point in lifting does the difference between lengthened partials and full rom become negligible (if it even does)
I discovered Jeff in 2018. I was a fan since then and followed all his scientific based programs in muscle building. Though some influencers based result, I rather focus on the right pattern of exercise that I was making and that's why I subscribed to him. Following his program for me is a safety net ensuring the progress that I made and safe execution in each exercise so I will not injure myself and make the best workout that I can make for myself. You're the man, Jeff.
Full ROM contains the lengthened partial portion. I think this study actually supports the hypothesis that lengthened partials portion is the main portion responsible for the majority of muscle growth.
Yes. That's what I'm confused about. Shouldn't the study have been long length vs short length?
@@petergianakopoulos4926yep
@@petergianakopoulos4926 tell jeff
I think the intent of the study was direct comparison. Full range of motion is the baseline, so you have to use it.
I think this study shows clear evidence that the lengthened partial is the business end of the lift, so now they need to find a way to compare net time under tension, which could mean higher volume, same fatigue in LP.
@@Tikemorris78 agreed and great way to put it
To many folks out there who talk out of the arse because they pull their talking points out from the snow channel. I have been lifting for close to 30 years and after listening to Jeff's advice about incorporating the stretch element in the lift I have found amazing results! especially at my age of 47 and I can't do the type of workouts I used to do when i was in my 20s and 30s since my joints aren't just what they used to be.. Thanks Jeff for doing the homework and letting the rest of us borrow your notes!
8:22 the " hey!! I care about this stuff " respect for that man. Recently started working out, appreciate all the guidance you give🙏🙏❤️
This was such an insightful experiment! It's fascinating to see that lengthened partials can be just as effective as full range of motion. Definitely going to incorporate more of this into my training. Great work and thanks for backing it up with solid research! 💪🔥
It's definitely still very impactful to our idea of how best to train overall. Like people have mentioned, a combination of the two methods could result in much greater gains. I can train an exercise with full ROM for say 10 reps before I can't do another full rep, and then switch to lengthened partials and get a few more reps. More volume, essentially more gains. Another thought, because you may be able to do more weight with a lengthened partial, you could use this as a progression scheme. Lateral raises come to mind immediately as going from the 20lb to 25lb dumbbells is a huge jump. Instead, I could do partials until I can do full ROM and then increase the weight. Reset back to partials, and so on. In the long term, this may result in greater gains purely because the lifter can continue to progressively overload in a more straight forward manner.
Doing more volume doesn't equal more gains, you just want to maximize mechanical tension(last 5 reps to failure) and minimize fatigue. And for the progression scheme thing, just use a more stable exercise that you can overload like a human. Cable lateral raise or even chest supported dumbel lateral raise is a milion times more stable and u can overload the exercise far easier
@@arsong9723 Crazy how wrong you are.
@@inkedgemini very insightful wow
The thing I've taken from lengthened partials is you can take full ROM to within 1 of failure, then crank out a few more with a lengthened partial to potentially get a lit a bit more out of it.
Love that despite all the contrarians, Jeff Nippard still continues what he does best. He went ahead and further expanded the studies trying to understand what's going on. Data wins overall. You may "feel" or "think" something is a certain way but knowing for certain what is and what is not will always yield what you expect.

Thank You For Being My Friend! 🐎
our focus on the importance of the stretched part of a lift is a refreshing perspective that challenges conventional wisdom.
I found your discussion on the study design particularly insightful. By using a within-subjects approach, you effectively control for genetic variability, which is often overlooked in fitness research. This method not only strengthens the validity of your findings but also provides a clearer picture of how different training modalities impact muscle growth.
Additionally, I think it’s crucial to highlight the practical applications of your findings for everyday lifters. Many people may not realize that incorporating lengthened partials can enhance their training results, especially for those who may struggle with full range of motion due to mobility issues.
I’m excited to see the results of your study and how they might influence the broader fitness community. Keep pushing the boundaries of our understanding in training science!

I have been lifting since I was 12. I'm 32 now.
I'm 5'6 and my max bench was 350 (weighing 158lbs, natural).
A big part of lifting, for me, has been understanding that it's just not that complicated. Do what works for you, to an extent. ROM is important and improves your physique.
I am completely content where I am at naturally. Being 5'6, the extra lbs make a difference. So, I lift to maintain. I don't go crazy anymore. I workout 30-40 mins max. There's no need to be in the gym for 2-3 hours.

It would be interesting to see a study where :

How did you account for the bias of right vs left muscle dominance? I feel like even trained people have muscle imbalances.
It's based on the % increase rather than the actual increase.
@@alastairkennett7794 Yes, but if you usually train using both arms with barbells, pullup bars, etc, your dominant arm might be doing slightly more work. So when you then train them separately one might expect the less developed arm to grow slightly more.
@@radix5315exactly what i thought, I don't know if he considered it
@@BeavisGoFIREFIREFIRE like how would you set the weights in first place, right? I always work both sides at the same time and i set the weight to be hard enough for the weaker hand so it would definitely be easier for my right arm (good one) to lift, if i did them separately
You cant have higher increases because of muscle dominance that is in any way significant if you have people who been lifting for 5 years.
Its not like they've been lifting with one arm exclusively so the other now sees newbie gains.
But regardless, the simple solution would be to have half of them work left-full ROM, right LLP, and the other half left LLP, right full ROM
I agree with Sam saying "Go fucking hard". But if I am going to annihilate myself at the gym, I would like to squeeze every last bit of gains out of it as I can. I think a lot of people who repeat this mentality are more focused on the feeling of having completed a difficult workout than actual growth
not everyone is open to have a pharmacy in their veins
Honestly, this is one of the best content creators I have seen.
Top notch quality!
One thing I feel like the anti-stretch/lengthened partial crowd doesn’t acknowledge is that performing an exercise in that way can sometimes cut out excessive fatigue. They’ll say “well, see, no statistical difference so just do full reps”, but if you cut out the squeeze part of the movement on something like a fly or lat pulldown I’d wager you’re cutting out a lot of fatigue as well. Both intra-workout, and accumulative over a training block, meaning there’s potential to perform more sets, accrue more stimulus, and still adequately recover.
I came looking for a comment like this. Agreed
I totally disagree. The lengthened position is way more fatiguing relative to contraction based exercises. Preacher curls are better than spider curls, but you can do way more sets of spider curls.
the lengthened part of a lift is the most damaging portion of the lift so you're actually completely wrong. And no muscles don't grow from "micro-tears"
@@sebbiesydenham3077 If I was talking only about producing more physical damage to the muscle, I would agree.
But I was mostly talking in terms of nervous system fatigue. Like going psycho mode on the last few reps of the pulldown insisting on having the bar touch your chest on every rep. Personally, I find that it’s there where I get the most fatigued, and if I cut that part out I’m able to go harder and feel better on the subsequent sets than if I spent a lot of energy on that squeeze portion of the rep.
@@symphinx you’re wrong again. If you’re matching RIR then the systemic fatigue will be the same. The only difference is muscle fatigue from LLP is greater than full Rom. More muscle damage, more fatigue, longer recovery time. All of that for no added hypertrophy benefit. LLP are literally a pointless concept being pushed by PHD holders for clicks online.
Honestly ive been working out for a year and then decided to give more attention to the form, the range of motion, controlling the negative AND choosing exercises focusing on a deep stretch and holding it for about 2 seconds. And my gains skyrocketed. I aint saying this is the holy grail, but i changed something in my trainingstyle and something changed in my gains... thats just what im sayin 🤷♂️
Full ROM or Partials? Why not both? Full ROM in the beginning and then take your set to failure with partials at the stretched portion of the lift.
Beauty Vid Jeff!
Too much fatigue.
yeah I was thinking on doing that in the last set once I reach failure
@@savonmies8479Lol
@@savonmies8479 dont do it every set with every exercise obviously. Should depend on what body part is your focus at that time or how rested you are etc.
I dont think you arę wrong. Im consistent with your advices and IT all works very well. I can safely say that my last 6 month progress was all thanks to you.
Got two questions:
1) Were the results the same when using the dominant vs non-dominant side?
2) When using LLP, it feels a bit easier to carry the weight. So you can either increase the weight and do the same amount of reps as in the Full ROM or you can increase the reps with the same weight. Was that taken into account?
Been using your full body program for 6mo and gained 10kg so far. Big fan of your work
Jeff makes it seem like partials are just easier and give the same results, but like you said but you'd have to do more weight or more reps, which doesn't sound any easier than just doing full rom. And also, more weight means more wear and tear on your bones and tendons, which take way longer to heal than muscles do.
I also need answer to 2.
Also food intake per subject
Can i get the program?
thats what I was thinking aswell and if they increase the reps or weight on the LLP does this not just equate to progressive overload
The big takeaway for me: doesn't really matter whether you do full ROM or lengthened partials. You basically can't go wrong with either one. As long as you avoid shortened partials you're good.
That and actually workout/manage recovery well. I know it sounds counter productive/intuitive, but some people enjoy working out in what would be suboptimal ways. They make up for it with consistency and work ethic. If you aren't paid to be an athlete I feel like all the nuance of what is optimal and what isn't really isn't something everyone needs to overly worry about.
@@Yetis-o3zFor sure. Consistency is the main ingredient. May not do it optimally but if you grind on a regular basis, you have it good.
@Yetis-o3z well said brother, as long it's done safely, it shouldn't be an issue for us normal folk

I call it "finishing set"
