I know this is just a single case, but since I've started training I forced myself to increase flexibility and fix my shoulder, elbows and posture, and even now after gaining a decent amount of muscle, I stretch for about 10min before and after training and I think that it significantly improves recovery (based on instances when I didn't do it). It's a mix of static and dynamic stretching, I always finish my ritual with some extra dynamic movements until my joints feel well lubed, and I always pop all the joints I can before I start weightlifting. It fixed all of my problems.
Im positive it does. I quit stretching between sets last year for a bit and I got tendonitis really fast. Soon as I started stretching again it went away. No way I could make gains without it.
This video is pure gold it's funny that he mentioned chest and poor posture because I struggled for years to bring my shoulders back and to develop my chest
Once again straight to the science, zero bullshit, absolutely agree with everything here (doctor here). Another quality video. Not only that but this actually convinced me to integrate stretching at the end of every training session (as inspired by you I've already integrated more stretch-exercises in my routines). Keep up the good work!
Dear John, can you do a video on neck muscles, and how to position your neck and head during exercises (like your straight tricep pushdowns), Thanks so much for all your help, you have made my training so much more effective!
Dang deep well of information right here! Been going through some of these older videos. John's humility to have others on his channel to add to his vast wealth of knowledge is just so dang awesome! You are a superhero, John! RIP Mountain Dog! 🙏

Hey man, thanks for the input. always love the way you present the practical takeaways of theoretical approaches and i really appreciate you sharing your experience. Just a little comment on the terminology "shortened muscle" : Actually the length of the sarcomers cannot get influenced as stated here. It's the neurological part of the muscle (musclespindles, nocireceptors and golgi tendon organs) that will inhibit the range of motion (which comes from for example being in a shortened position for a very long period of time) in order to protect the structures (muscles, joints, tendons etc) from being injured by ROMs that the structures are not used to. This was shown in a study where subjects with very "shortened muscles" ,or as i'd rather say mobility deficiencies, were put into anesthesia and then the muscles could be stretched into the full range of motion without a problem occuring to the subjects during and after the test, because the neurological parts of the muscle were not inhibiting the stretch. That's why it's not called a shortened muscle or muscular imbalance anymore but athro-neuromuscular imbalance. Feel free to discuss this, I'd love to hear your feedback. :) PS: please don't send the ultimate mountain dog to hit me with a chair for writing such a smartass comment. Also sorry for the bad grammar and greetings from Germany!
So much great information! Thank you! That aside, after stopping overhead presses for a month (to reduce injury risk as I go for heavy bench press PR soon) I noticed my front delts become smaller. I decided to add in 45 degree incline dumbell presses to my push days and I start the exercise by mainly using my delts, then I use mind muscle connection to have my pecs pump out a few more reps mid set. Works like a charm.
It rather surprise me that you mention that doing partial ROM is good for muscle building because in the book of Brad Schoenfeld all studies say that full ROM is the best way for hypertrophy. It is contradiction to what he mentions as his first point namely the length of muscle. Maybe you will give a comment on this? Other points like loaded stretching motivates me to give it a try, great video. Your guest did not give an answer on the question when to stretch, am I correct? In many sports people do stretching before (as a warm up) and after the training (as a way to release waist products).
Maybe bro science on my part.... But I think the best time to stretch is after cardio... done on the day following a workout. So if I do back on Tuesday.... Wednesday I would do cardio and stretch my back after. At least I feel I'm getting the best results doing it this way. Also been testing mini workouts the day after cardio to pump blood back into the muscles... Then eating beets to get more blood movement. Pineapple and beets maybe the most under appreciated foods. These videos get me thinking too much lol
You addressed the concept of lengthening the muscle and thus increasing hypertrophy, how do you feel about using stretching as a means of increasing blood flow which should increase hypertrophy/recovery as well?
Stretching per se (especially with an active contraction) will decrease blood flow during the stretch, but if held long enough / contracted hard enough create a reactive hyperemic effect (blood flow increases afterwards). This can create a really nice pump, which may be a causative factor in muscle growth, as well as possibly cause what's called ischemic pre-conditioning, whereby the rapid flood / surge in oxygenation causes a free radical stress that evokes a protective response in the muscle (protecting it from free radical damage). There's likely something going on here, as free radical stress is part of the stimulus for exercise adaptation (animal models suggest that anti-oxidants impair muscle hypertrophy), but what's going on, I'm not sure. It's a complicated story here (probably more than you wanted to know) as BFR / Occlusion training causes metabolic stress (which occurs with stretching while contracting the muscle / a loaded stretch) but there's one study suggesting that if you training normally and occlude (no contraction, though and not under stretch - just apply a tourniquet to cause occlusion), that this might reduce muscle growth (meaning that the post-exercise blood flow is important to driving the signal for muscle growth a/o that metabolic stress Without a concomitant contraction may not in and of itself be a stimulus for muscle growth per se.
Excellent video. Man John inspires me, I am doing his Medows row every back day. Like he is gone hut he is not. I will definitely use this info. Namaste🙏
I like the stretching on the way up when I do lats pull downs I just in joy the feeling and the dumbbell pullover after bench. A friend of mine had a bad experience stretching his biceps after concentration curl he felt a pull on the lower part of his bicep he couldn't curl for awhile. Bad experience I guess. I agree in stretching the muscle it also helps to stay flexible. Yup!
It`s a mean, Impressive amount of information (in a good way) for people that has not the necessary physilogic base to understand the muscle. But for people whom understand it, gaaad daamn, Just fucking answer If it GROWTHS or NOT, not what you think about it, the entire half of the video respectable man.
Stretching is great. I usually stretch before a workout tho...then I'll do some light reps to get the muscles pumped before I start working my weight up. But I do agree that you should probably hold off on the more aggressive stretching after the workout. I just do it backwards because it just feels better for me.
John, doesn’t hard stretching actually relax your muscles hence why you experienced the muscle instability?? I found light stretching before lifting is great to increase mind muscle connections and hard after which helps recovery. Love your content
It's definitely an important topic. I hope this is covered in future videos. Maybe show some of the proper stretching techniques for each of the muscle groups and when to use them in a workout.👍
Experiencing some tendinitis in my left elbow area. Any stretches or exercises that will address the muscle and NOT the tendon? Great info as always John.
I'd see a practitioner there. (It doesn't sound like you're quite sure even what tendons and therefore which muscles are involved. Hard to do so and also probably not a good idea to give medical advice online, IMO. :) )
dynamic movement before exercise static stretching post-exercise 20 min stretch off per hour of training was something I was told hot yoga or vinyasa yoga for sure helps create long muscles with a pleasant sweep i would not do excessive stretching before any power movements, you just activate the muscle their is a balance on a final, I injured my triceps a few years ago and yoga brought back the balance in my arms through the statics I think, so for older guys looking to keep the shape and muscles activated I say do two or three yoga sessions a week. yoga helps you work on your breathing as a lot of lifters hold their breath when pushing hard I have seen.
So i am a gym goer and i have been skipping leg day because i am a piece of shit but i have started stretching everyday because i want to do martial arts so stretching for kicks. From stretching alone every day for 15-20 i swear my legs are bigger than they been in a long time just from Stretching or is this just a mental thing.
Hey John, I tore Both hamstrings 2 years ago, and my therapist said I would be more susceptible to Injury after the trauma. Just about 2 weeks ago, I was stretching my Hamstrings with a resistance band between a set of deadlifts and pulled my left Hamstring . I dont do static stretching before a workout anymore because I have lost alot of mobility in my hips, back, and ankles. I do more active warmups like Stairmaster and high reps low weight exercises . My question is, How can someone with past injuries promote muscle growth as a substitute for stretching when they have lost mobility? I find that stretching puts me at a greater risk of injury.
Stretch after. Stretching before hinders explosiveness and strength. All it does is release and lengthen the muscle. Stretch post workout, in the morning, etc. Dynamic warmups are superior for athletic or strength activities.
You just got a shout out in a juji and Tom how to make a career in exercise video. They mentioned your forearms, oh yeah Brian Shaw was talking about it too!!! I think it's at 5:58

I have no idea what this guy is talking about. If you don’t want you shoulders to slump forward, then you must work the back just as much as the front.
John whats your thoughts on Fascial Stretch by trained person after a few minutes after workouts end. I try to get it done every few weeks if i feel tight.
@@redcarsplodge1837 I do to. I have to or I get charlie horses and lock up. I blast the crap out of mine. Sometimes I hit them so hard I cant tell if I tore one the pain is so bad.
The ROM and exercise selection are all things i have discovered in the last year. I am a LONG limbed guy, tip to tip i am about 78" at 6'2, pressing has always sucked for me, and gains come very difficult, until i started working in the roms, where i could actively squeeze the muscle and use exercises that I can connect with. Scott's stretchs are evil btw lol
I saw that u never got a response, so hopefully my insight can help a bit. Stretching is more advantageous to perform at the end or after your workouts in order to increase blood flow, thus helping recovery. Stretching before resistance training can weaken your muscle fibers, and cause injury.
