About the speaker :
Doug McGuff, MD became interested in exercise at the age of 15 when he first read Arthur Jones' Nautilus Training Bulletin No. 2. His interest in exercise and biology led him into a career in medicine. In 1989, he graduated from the University of Texas Medical School at San Antonio and went on to train in Emergency Medicine at the University of Arkansas for Medical Sciences at Little Rock where he served as Chief Resident. From there, Dr. McGuff served as Faculty in the Wright State University Emergency Medicine Residency and was a staff Emergency Physician at Wright-Patterson AFB Hospital.
Throughout his career Dr. McGuff maintained his interest in high intensity exercise. Doug realized a lifelong dream when he opened Ultimate Exercise in November, 1997. Over the past 13 years Dr. McGuff and his instructors have continued to explore the limits of exercise through their personal training clients at Ultimate Exercise.
In addition to his work at Ultimate Exercise, Dr. McGuff is a partner with Blue Ridge Emergency Physicians, P.A. Dr. McGuff Lives in Seneca, South Carolina with his wife of 25-years, and their Children Eric and Madeline.
Doug is the best selling co-author of Body by Science ( amzn.to/eBSQif ) and The Body by Science Question and Answer Book ( amzn.to/bUajU5 ).

It means jogging is a crappy way to perform a leg press for a half hour.
21 Studios well actually his TUL is one set to exhaustion from 90-120 sec for each muscle group. Watch his videos
Exactly! When lifting you do engage the aerobic subsystem of the cell but done properly it engages the anaerobic part of cell. That's where the awesome stuff happens..... It happens well after finishing the workout!
Steve Reeves was known to leg press 225 lbs. for 45 minutes straight:)
I ran 5 miles one time and I thought how do people keep doing this repetitive motion? No thanks
Hahahah
I love this tip. It could save so many people so much time. Push your muscles hard for short periods of time, instead of wasting time pushing them semi-hard over long periods.
"Train slower, train harder, train briefer." - Arthur Jones
I'm a huge fan of Dr. McGuff. He put me through a workout in 2009. Not only is this man extremely intelligent, but he looks the part of what he teaches about. Some trainers in the Slow Movement exercise field just don't look like they train. Dr. McGuff is someone who practices what he preaches. I've learned much from him the last 7 years, not only from meeting him, but watching his seminars on youtube. I'm sure by paying attention to him, I've sparred myself from injuries and have been able to add muscle and stay lean into my 50's

What he says is interesting. We're always told that your in better shape if your resting heart rate is lower or if your heart doesn't have to work as hard during and after exertion.
I lift twice a week as taught by McGuff, different muscle groups and walk up hill everyday for 20 minutes with some ten second wind sprints, works for me plus stretch every day, am stronger, better endurance and flexibility and endurance improved markedly with addition of ten second wind sprints.
Dr Doug McGuff talks are amazing. His book fantastic!
So clearly stated. Thanks.
The main long term of increase in VO2 max is increased oxygenation of the blood, and removal of CO2 due to increased lung capillarization, and that doesn't happen from isolated resistance training. The main short term adaptations are mitochondrial density. Neither of those are primary adaptations to resistance training in the optimal TUT. TUTs of 85+ seconds have been shown to produce less hypertrophic adaptations than TUTs between 12-85 seconds. Longer duration exercise PROBABLY causes type IIx fibers to convert to type I fibers (to genetically express a spectrum that would commonly be thought of as slow twitch. We know that type I an IIB (and other along the spectrum) revert to IIx in paralysis victims and with extended immobilization. Lung capillarization requires multiple large muscle groups to be used simultaneously (at advanced stages). A "set" will either result in failure due to inability to produce threshold force due to anaerobic factors or due to aerobic factors and if failure occurs due to aerobic factors than by definition you have not achieved anaerobic failure. That doesn't matter so much since the last rep of a set done to failure with high voluntary and reflexive force actually is LESS productive than prior reps which can achieve higher peak forces. If you try to flex a muscle as hard as possible, the stimulus to systematic fatigue area under the curve is probably greatest at 50-75% of maximum duration, not at 100%.
Nice Doug Clip, Keep 'Em Coming
Can someone break this down in layman's terms? Is his argument that true cardio is having a stronger heart and that can only be obtained my muscular exertion via an anaerobic method ( kettle bells , sprints, Hit). That steady state cardio is not an efficient means of strengthening your heart and that it compromises your health to do so?
jsagers2008 That is the basic message. This idea orginatined from Arthur Jones who believed that steady state aerobics caused wear and tear to joints faster than HIT.
In layman's terms, this is total nonsense.
so basically i need to use resistance weights rather than running to improve my cardio vascular system....will that in turn improve my vo2 max ??????
andypowlesland1 Spoz try watching his entire Bio Chemistry 101 on 2010’s 21 Convention. You will then understand. This was only a snippet at the end & missed the explanation 😀 he explains VO2 Max
Yes !
jogging is horrible. i have science to back that up.
jogging is wonderful. i have science to back that up.
AIN'T YOU TUBE GREAT ! ? ! ?
no one's saying jogging is horrible, it's just that we've learned there are better, safer ways to be healthy.
heh yes and it's like that with diet and other stuff too.
Hey brother just use your discernment, some people will claim they have a study that says they sky is plaid and not blue... look at things through the most optimal lens and you cant go wrong. Jogging is a terrible way to perform cardio period, some get results sure, but you will get injured because running is "chronic overuse and sarcopeniac" by nature. Again use true discernment of logic and psuedo logic..👍
HIT Fitness ok what about cycling vs weight training. I want to know about them. I just went back to cycling because I feel it’s better for longevity. Do you have any info
@@richardfecteau4490 aren't we evolved for running and hunting? Why is cardio jogging so bad
hmmm
Honest question guys. Will switching to his program still allow me to do sustained physically active work (what’s considered traditional aerobics) when needed? For example...sex.
If you want to run more...run more...if you want more sex....
@@daneck100 Except with traditional cardio, you can still get a good amount of crossover. Is there still a lot of crossover with this technique
No
If it did that means u could do his training and go run a marathon
I like these little snippets. My girlfriend has a short attention span and these help in getting the point across to her before she glazes over.
I feel you
Okay, Little Tater Tot! “girlfriend”.
:02-- Cardio bunny ... Ain't that cute ... How about this young owner of a bunny man, if 'your bunny' is doing something that might be mislabeled here, but it IS still beneficial to some degree, MAYBE not beneficial to the highest degree, MAYBE not the lowest degree either, BUT still beneficial , why not let 'your bunny' do it UNLESS it is causing pain or something worst? CAN you get off your high-horse in that SINGLE case with 'your bunny'? Or are you gonna force 'your bunny' under 'your thumb'?
Soo, what does this all mean?

cardio means heart. Period. Weight training is the best cardio you could ever do.
youre welcome.
i love how you bring science to this topic as opposed to the social nonsense that comes attached to this stuff etc i believe isometric holds are key and extensive cardio is a waste f time. I have a bs physics degree btw.
yes your degree is bs alright
How to train enzimes?
A good set of enzyme press to failure should do the job. I personally prefer putting myself under a hydraulic press until failure, that’s where the real stuff is!
Modern day Mike Mentzer lol
Can I do succesful HIT while taking beta blockers?
This explanation of cardiovascular adaptation is flawed. It is true that sort term adaptions in cardiovascular/aerobic improvements (basically VO2 max) are at the cellular, muscular level (increases in mitochondria, lactic acid dehydrogenase enzymes and increased perfusion of the muscle) these adaptations are rapid, and plateau very quickly, on the scale of 6-12 weeks. Untrained subjects can rapidly improve VO2max by those local mechanisms, but will hit their ceiling quickly. At that point the body can only make further adaptations systemically, by increasing stroke volume, and at the "base" of the pyramid, by increasing capillary density of the capillaries that pull oxygen out of the lungs. Elite aerobic athletes have utterly maxed their peripheral adaptations and can only make additional improvements in rate of work output by systemic changes, primarily how much oxygen they pull out of the lungs.
The body prefers to make specific adaptations first, such as increasing the oxidative capacity of the muscles that have been stressed. If lung capillaries increase, but the muscles don't have the extra mitochondria to process it, it is wasted. Also if someone is only using a few muscles for endurance based activities, then it is a waste to cause adaptations in muscles that aren't being used. If you only use your upper body, or one arm to do a lot of work, it is a waste of resources to raise systematic capacity. Also, the body is unlikely to be able to stress the ability to extract oxygen from the lungs if only half the body is use for the activity. Who cares if the heart can deliver more blood, or if the blood is more oxygenated, if the muscles can extract the oxygen or have the machinery to use it to burn fuel?
The point is that most people can extract plenty of oxygen from the lungs and deliver it to working muscles relative to their muscles' ability to process it, and so the best way to fine tune aerobic capacity is to increase utilization at the local muscular level, but after 6-12 weeks or so, this mechanism is using all of the oxygen your system can supply and the only way to increase further is to supply more, an ultimately, the capillarization of the lungs is the limiting factor.
Sure, if you define conditioning to be the set of adaptations provided by strength training, then of course strength training provides it. If you define conditioning the way the rest of the world does - i.e., the level of continuous power production you can sustain - then it declines steadily and markedly if you do nothing but strength training. This shouldn't come as a surprise to anyone, because you get better at what you train for and worse at what you don't. There's no magic going on!
I think his point is the heart doesn’t know if you running or walking or sprinting or lifting heaving weights it just responds to the demands placed upon it. Those demands reduce over time when you train due to adaptive responses that primarily take place in the working muscles
Strength training is an efficient way to bring about those changes if done with sufficient intensity and minimal rest in between exercises.
However if you want to get better at running you need to run more as running is a skill like any other skill and requires practice
But most athletes are doing training that has nothing to do with what they are training for, such as jogging along side combat sports. Jogging makes you better at jogging, it doesn't make you a better fighter.
This is not against the video this is against UA-cam constant constant and more constant advertising okay why don't UA-cam just get a free a free advertisement advertisement Channel and every now and then throws something in that people would actually want to listen to and UA-cam If you use this idea I want 10 million dollars for it
Ilhlll
I'm with Mr. McGruff on his ideas but if CARIO & aerobics are mislabeled or not, this just a meaningless point; it is beneficial to the human body in some way; maybe not the best but it is helpful to the human animal, both physically and mentally.
Cardio is to burn calories only I guess.
And is very inefficient at doing so.
"Cardio" causes metabolic-rate to drop. See: John Keifer, *_Why women should not run._*
Blah Blah the fact is you need it all to a degree strength training, cardio and stretching and a well balanced diet
No....you dont
All you need is HIT and diet
You walk all day
You dont need to just walk for 30 min and label that exercise
Have you ever worn a heart rate monitor it takes at least 10 min before you really see a spike in heart rate...unless you increase speed. If you walk at same pace lets say 3mph...it will take 10-15 min before you see a good increase in heart rate...
Bc in the begining your muscles arent fatigued. As they begin to work harder...lets say 30 min in you will see an increase in heart rate without increasing speed. If you did an hour...again there would be an increase, bc again your muscles are more fatigued
The question is...why the fuck would you want to wait an hour to fatigue the muscle thats creates the stress that then stimulates the heart? I can do in 4 min what you will do in an hour just by doing HIT cardio like tabata. Call it nom semse all you want,but im willing to bet im bigger faster stronger leaner and in better shape than YOU and i only exercise less than 2 hours per week.
@@summondominion wow you are very incredibly wrong. HiT does NOT induce bdnf hydrolysis which is extremely beneficial for brain health. Only long bouts of cardiovascular exercise does. You're not very bright are you.
@@summondominion why walk? low impact movement is good for joints. it's good for stabilizer muscles, feet muscle if you wear the right shoes. its great for mental health. etc, etc, etc. you have the typical american mentality that craves instant results and the need for a perceived hyper efficiency.
@j1j1j1j1j1 you missed the entire point....walking is inefficient for weight loss if you value your time. High intensity cardio session of running stairs pushing pulling sleds boxing with a heavy bag sprinting jogging burn way more calories in a fraction of the time. You walk all day.
I didn't miss the point. Your argument that walking is not exercise is not correct, especially for unfit individuals, for whom walking may be more strenuous for them than running may be for someone else.
dang the olympians got it all wrong. get those marathoners on the leg press, pronto!
This refers to general health, obviously competitive runners have to run.
Thats running as a sport. Hes talking about training for general health and fitness.
@@adam-lt8iy it's been a while but it sounded like the claim was that the hypertrophy training was the most efficient for cardio as well. my bad if that wasn't what he was saying.
running is not an exercise. It's running!
I think people do typical cardio workouts like running because they can work the cardiovascular system for a longer period of time as opposed to HIT which you will only be able to work 30 mins maximum ( not saying cardio is important though)
Spoz Yeah but that's the point of HIT - exercising for a 'longer' period of time should not be goal.
