Lengthened Partials are Better?

[@Kevin-The-PHDmentor]

Dr McGuff, this was an excellent video. You need to do more short two or three minute clips like this. They say what needs to be said and are very practical

[@stevesorensen9648]

Very insightful, and I agree 100%. It seems to me when I watch people at the gym, they're simply just trying to get through the set. They want the set to be over so they can get to the next one and so on. I did the same thing years ago. Controlling the movement and really focusing has helped me enomorously.

More reactions and opinions in this format Doug!! It's always a pleasure to find a video of yours in KZbin notifications.

[@HighIntensityBusiness]

Love the short video Doug. Keep it up. Great insights! I was curious if it made any real difference...

[@Dan-jo8py]

I feel like some of these studies are also forgetting about program design. I can see in theory how one of the studies comparing overhead cable triceps extensions compared to standard triceps pushdowns has found a much greater impact of the overhead version for instance - the overhead version puts an isometric strain on the long head, which is mostly an arm extended and not an elbow extender, so wouldn't be worked as much in the standard pushdown. But that ignores most people's actual work outs - if you only did one exercise, then yes maybe an overhead beats a pushdown, but if you're doing a pull over or straight arm pull down you'll then work the long head when doing your back, and who isn't working their back?

[@Omnis2]

I tend to agree with you and can’t really find anywhere in most of the studies where it is mentioned how the subjects are actually lifting. However, there seems to be evidence for hypertrophy in the lengthened position vs shortened when isometric resistance is used. Isokinetic dynamometry studies also seem to have maybe a tiny improvement to hypertrophy but mostly it’s a wash and the full ROM groups either had more strength at the end or it was also a wash. Just don’t skip leg day.

[@adligtvoet7185]

My 2cents, stretch mediated hypertrophy happens fairly quickly if one is new to strength training. In the "stretch position"there can be a stimulus for this to happen if the resistance is enough and time in that position long enough. This even doesn't happen in every muscle. The stretch position itself doesn't stimulate the muscle to become "thicker". We for sure won't see people that workout sensible and look muscular growing for this new hype method. Train hard and smart beats marketing every time.

[@stringlarson1247]

I'm so glad that I found Dr. McGuff and BBS over 10 years ago. I've adapted these concepts into pre/post-op PT as well. I see so many people at the gym who are all 'swole up' but have poor ROM and very unbalanced muscle development.

[@jonjacob2717]

There are studies on tempo that show not much difference if it is somewhat reasonable (4s> &

[@dr.dougmcguff282]

Also consider that a lot of the top position in many movements is significantly underloaded either because of moment arm effects or joint angles nearing lockout. This makes the bottom section look better by comparison for many if not most movements.

[@DeNiruable]

​@@dr.dougmcguff282But how does that negate the argument that you see a slight increase of hypertrophy in the stretched position if in most exercises the load is in fact the greatest while in the lenghged position. Wouldn't this only support the claim that focusing on the lenghtend part would be theoretically better?

[@jdubruyn]

Thanks Dr. McGuff. I've been a fan of your work since about 2014... My most creative idea about hypertrophy is from the bird wing study(which may co-incide with the lengthened partial study)... I don't think it's about the stretch in either instance and rather about the metabolic fatigue being a constant* factor under a/heavy load(as all energy pathways are utilized simultaneously but more importantly... continually... and thus growth is the only other option). This being partially(ironic) achieved in training to failure as is the generally accepted way to achieve hypertrophy. I think my idea overlaps with your hypothesis as well Dr. McGuff so maybe we're on to something😅I used to be good at biology in school with some kind of talent for medicine🙏 One day when I have time in real life I will train one set to failure three times a day to prove my hypothesis😅Obviously nutrition would also play an important a role... I've been training for 20 years now(36) and I can't think of anything better that's the real cause for inducing maximum hypertrophy in conjunction to/with all the ancillary mechanisms that support muscle growth indirectly. Always good to see you post another video Dr. McGuff you're an inspiration to many of us🙂🙌

[@dr.dougmcguff282]

The hanging weight on the wing technique for invoking hypertrophy wasn't done necessarily because it is the best way for humans to stimulate hypertrophy...it's just the only way you can get an animal to "lift weights".

[@craigpawlisch8628]

An interesting thought, but not persuasive without quantification. How much unloading do you actually get from momentum? Is it 1%, 10%, 50%? Where in the movement does it occur? Makes a difference where the acceleration and deacceleration occur relative to the strength curve of the exercise.

[@BlueBeeMCMLXI]

When I worked out that my body wanted to stay under load - not run away from it - was when I made better muscle. To count through the movement makes sense.

[@blainebowling3303]

…or could it be mechanical load int the lengthened position due to leverage is creating more absolute load?

[@Torben118]

No, that really works well. I tried it with free weights during the Lockdowns, of course slowly and very strict and mixed it with Loaded Stretching. Was sceptic at the start, but it’s a great tool. But not recommendable for the broad Gym customers because of the potential danger.

[@BruceThomson]

'Makes sense. These days at the outdoor gym, I don't even count reps, I simply exhaust the muscle to failure to bear load, and while almost entirely in the contracted state, to build the lactate burn that tells the muscle to grow.

[@Oettam_201lbs]

Everything is better than what people are doing in the gym for 8-9 hours a week.

[@donnahelps5680]

Yep.. totally agree

[@dtm4071]

So where are the big HITters?

[@garyinternet5436]

Short video but incredibly insightful. Most people out there don't even see speed of movement as a training variable that they can manipulate. But that's understandable when you consider that so much training information stems from competitive powerlifting where moving quickly with what we would see as poor form is extremely helpful because it helps you maximize load relative to fatigue, and that's the name of the game in powerlifting. The default setting for this kind of training is just to move as fast as possible all the time regardless of anything else. And then with the training that comes from the realm of bodybuilding, it's all about moving faster to achieve a high volume of mechanical work because that's believed to be necessary. Everything mainstream says that you should be performing reps quickly. Faster reps means more momentum and that results in partials allegedly being better. It also results in multiple sets allegedly being better, higher reps being better, more frequent training being better. Faster reps is literally the thing that gives birth to everything else that is injurious, inefficient and ineffective for people who aren't on the far right of the bell curve, or using drugs.

[@dtm4071]

Yeah sure, So where are all the big HITters with their super slow reps?

[@Alan-qv7fv]

​@@dtm4071you are in every single HIT video 😂. At least I respect your commitment.

[@garyinternet5436]

Where are they? I don't know. Maybe you're right. Maybe there are none. I could just as easily as a similar question of you. Where are the high volume, high frequency trainees who 100% lifetime naturals and are large and muscular without being any kind of physique competitor, powerlifter, model, professional or semi-professional athlete, or Fitness KZbinr/Influencer and who are training in that manner whilst juggling a job, house, family, friends, other hobbies and interests. I'm fairly sure those people don't exist either. Drew Baye uses exogenous testosterone, but he still proves that SuperSlow is effective as a training stimulus. His choice of training stimulus is THE major difference between him and a myriad of other people online that have very similar physiques.

[@dtm4071]

@@garyinternet5436I juggle life just fine whilst spending an hour or so daily in the gym. Drew Baye looked terrible before TRT. Funny how when I ask this question no one says "me". Why hasn't HIT got you big? Why doesn't it work when it is always touted the best for naturals? All I get is the "genetics" excuse in reply.

[@Alan-qv7fv]

@@dtm4071 I'm big for my standards working out 2x a week (25min each workout). This answers your question?

[@Tezzab4]

This doesn't make much sense to me because the subjects who were training in any of the partial ROMs of an exercise would not probably be deloading much to any great extent. They were not just comparing lengthened partials to full range but to other partial ROMs too. I.e bottom, middle and top 1/3 ROMs. Lengthened or bottom 1/3 were superior in all cases AFAIK.

[@DONYAARANETA]

In the years since Body by Science was released, we've seen the rise of "fitness influencers," as social media has grown. Along with that, have come the proliferation of bullshit notions like this, and many others. Combine that with various studies that confirm what people on our side of the fence have been screaming from the rooftops since time immemorial, and your own expanding thoughts on things, I think the time is ripe for a Body by Science II: Electric Boogaloo. I know your main career eats up most of your time, but please, sir, if you can find a way to make it happen, I think the world needs it more than ever.

[@fakenattypolice8317]

Just speculating with this

[@Greynwhite]

Salute to you.. 👌

[@exercisethoughtsanddiscussions]

Well designed equipment already has ‘loaded stretch’. Poor exercise choices are the cause of this thinking. If proper exercise choices are made, there is no need to even consider, ‘loaded stretch partials’. Well designed equipment and proper exercise choices include it already.

[@dennisrkb]

All the studies are wrong.
