Lengthened Partials for Bozos

[@stevesorensen9648]

Such a valid point made here and explained very clearly. Thank you Dr. McGuff.

[@MrOrthodox13]

Can't believe that I've never heard about active and passive insufficiency, now I have more terms to pretend not to care about while I do my regular curls and pull-ups.

Dr. Doug joining the high frequency club in regards to uploads !

I'm trying.

[@tonysilvaalmeida7586]

Body By Science is here, with this guy! Thanks Doc. Hope for a 2nd edition of your Book warming us of those recent fake informations!!

[@ChrisGraeme]

People need to read Bill DeSimone’s work.

[@dr.dougmcguff282]

Yes. He explains these issues with great clarity.

[@georgewilkie3580]

My sincere THANKS to You, Doctor McGuff. Your scientific based information is invaluable to we of the Bodybuilding/Strength Sports community.

[@stevewise1656]

I absolutely agree! It made no sense for me from the beginning because Actin a and Myosin never crossover Lengthened partials have already been debunked by the same people who'd been advocating it. I give them respect for running a proper study that proved full ROM is better than lengthened partials.

[@clmb511]

Would love to see you tackle the ideas around variable resistance curves (Prime), Kas sets, eccentric overload (x-force/ Technogym biostrength) on a future video.

[@magnus6231]

Second this recommendation.

[@glenwalker12]

Yep, would love to see/hear that analysis

[@andypicken7848]

Really good stuff Doug. Thanks for posting

[@johnfisher8510]

I would think in the case of the "pelican curl" the level of internal rotation would be particularly un healthy in respect of the biceps tendon...

[@rmartin9426]

Always love to hear your views Dr. McGuff. I would love to hear you debate principles with the more civil exercise influencers with contrary opinions.

[@christopherchelius5563]

You are awesome man. Thanks for improving my life and health. Grateful to you.

[@dingafit4896]

thanks doc, good stuff as always. I just bought body by science, i'm excited to dig into it.

[@monkeyb1820]

I can see the uselessness of that motion (and that it needlessly ties up the cable machine). But is this the same motion as if you are sitting on a bench that is tilted back (so upper body is tilted back a bit) and you do dumb bell curls from there? The upper arm is probably not in 'as stretched' of a position as compared to the the cable usage you describe--but the arm is still somewhat stretched, not as strong as if you are sitting in regular upright position. Many online experts say that doing dumbbell curls while tilted back a bit is good (although I'm basically just doing a couple of sets of standing up barbell curls, going nice and slow).

Thank you for sharing this!

Doug, if you have time, more on different topics would be great, Thanks.

Ahhhh that ear piercing sound!

You heard that too? It was my shoulders screaming from just watching this.

Body by science came yesterday mcbuff. Already read the big five chapter, highlighted and re read parts

[@murrayknox4503]

Great content Dr. Doug. Q: Is there any benefit to doing partial reps - either top half or bottom half - at the end of a set?

[@SaturnReturns]

They might be doing cable pelican curls. I do cable pelican curls like that. It's to mimic the gymnastics ring movement. I personally love the exercise for biceps and know nothing about this new malarkey of "lengthened partials".

[@dr.dougmcguff282]

You should not perform exercise to mimic the movements of a sport, but instead, should be doing movements that track muscle and joint function. But hey....if you're lifting weights I'm happy. However, if the front of your shoulder ever starts to bother you, it is biceps tendonitis from overstretching your bicep tendon at the bicipital groove. If you think you should do this "because look at how big gymnasts biceps are" your are making an observational error of drawing conclusions based on selection bias. Gymnasts don't have big biceps because of these movements, at the elite level you select out for people with long/large biceps because they are the ones who can survive these ridiculous positions.

[@SaturnReturns]

@@dr.dougmcguff282 I personally really like the way the exercise feels and the stretch I get on my pecs and front delt from doing it. But I understand your point.

[@magnus6231]

Training a muscle in passive or active insufficiency is like cooking with seed oils !

[@Oatmate]

Yes, training at long muscle lenghts produce larger increases in muscle size, and using seed oils improve caridac outcomes

[@exercisethoughtsanddiscussions]

The example is exactly why I’m struggling to find a dynamic or static setup that I can produce FULL EFFORT with forearm musculature. Most exercises I’ve tried, full effort is not enabled. 🤔🤔🤔

[@dr.dougmcguff282]

Focus more on the fingers than the wrist. Power grip in a neutral position really hits the forearms. Holding dumbbells in a power grip position, allow them to roll down to the distal finger joint, then close your fingers into a power grip position with the handle tightly squeezed in your hand.

[@ruanoosthuizen6084]

​@dr.dougmcguff282 How can you roll the dumbell down to your fingertips if your hand is in a neutral position (like hammer curl position - is that what you meant?)

[@magnus6231]

I was always curious whether you are supposed to flex and extend your spine in the MedX Lumbar extension or just keep it neutral while doing the buffered hip extension which would make the latter movement redundant seeing that you might as well could to a static hold for the targeted musculature ?

[@TheHaiku2]

Good stuff!

[@ohno837]

What about deep squats…is that the same thing?

Going to use this in Judo

[@RickyRyan]

The title is misleading, it makes it sound as if these types of partials are bad. What you’re criticizing is form of movement. It has nothing to do with a properly applied partial.

[@dr.dougmcguff282]

As stated in the video, see the video on. this topic that immediately precedes this one. It gives my full thoughts on lengthened partials and why they may appear better.

[@FiddiTwo]

love it , boom

[@Stckit1]

Are you talking about lengthen partials or are you speaking to people that aren’t flexible? A lengthen partial is in the path of a full range movement…. The only thing I agree with is people doing weird shit to hyper extend for a better stretch. The title of this video is irrelevant to the info you provided within the video.

[@dr.dougmcguff282]

Lengthened partials might make some sense is biomechanics are correct. If you hyperextend you are doing "lengthened partials for bozos".

[@RickyRyan]

I agree

[@josefraguas2768]

love it! plain STUPID.....

[@bloodeagle2945]

Why do those "experts" don't know about active and passive insufficiency?

[@exercisethoughtsanddiscussions]

The experts also need courses in Statics and Dynamics, the only two possible ways to exercise, in engineering.

@@Dggb2345 do you have any ideas on that, off the top of your head? Training in space, I mean.

[@rgmann]

Most of what I see people doing in the gym is just "plain stupid." People simply don't want to believe that doing one or two basic movements for each muscle group, with proper form and a relatively slow cadence, is all that one needs for the growth and strength stimulus to be triggered. That's true whether you use one set to full concentric failure, or multiple sets shy of failure, or a combination of both. KISS folks! It works every time for everyone!
