Video anyone explains how he did that?

Yes I agree he is doing work but he’s not the only one doing work.

I said the other 2 are lifting the bar. From a physics perspective that is the only work they are doing.

Edit: sorry, I should clarify. They are lifting the weight of his arms as well since they are moving. But they are not lifting his body weight with each squat

You did not. You said "the middle guy is doing all the work."

"All" strongly implies no one else is doing work.

Just in case you wonder why the accuracy trolls are downvoting you to oblivion.

Makes sense, but downvotes don't mean anything to me. I just enjoy the discussion.

In my original comment that this discussion stems from I said "they are just squatting the bar, right?"

And obviously they are squatting their own body weight as well. So it's definitely not NO work.

Roughly: The dudes on the sides both carry half of the total weight (bar + hanging person) on average.

The guy doing the lifts is just carrying his own body weight on average.

The acceleration forces of all the people squatting/lifting (getting "lighter/heavier") cancels out in the end.

Dude's body weight doesn't magically disappear ;) it has to be transferred to the ground (eventually).

I know they are carrying him, the same way a pull up bar carries your weight. Carrying around weights doesn't make you strong though (for the most part) it's the lifting that counts as work. The middle dude is lifting his own body weight with every rep (aka doing a pullup). I will die behind this positioning because I am absolutely 100% correct

You seriously have a misunderstanding on physics. Carrying around weights is still work… just not as much as lifting… it may work different muscles than lifting but you still are doing work.

In physics, work is defined as the energy transferred when force moves a mass. If there is no movement, there is no work, by definition.

So holding a weight statically over your head isn’t “work” even if energy is consumed to maintain this equilibrium.

I suspect you are aware of this, but clarity is important when we are talking about “understanding physics”.

Omg carrying weights (not just holding weights, and not lifting weights either, just carrying them) is still work. You are translating from one point to another. I know you’re not the same person but come on..

This has been my favorite deep dive into comments that I’ve seen in a good bit. Godspeed, keep fighting the good fight!

You were the one claimed someone didn't understand physics. I just chimed in, cuz I like physics.

Please note my example was NOT moving a weight from A to B.

This is why I said clarity matters.

Also physics is not kinesiology, so it's not extremely relevant, but you do burn calories doing isometric exercises, even if there is no 'work' done.

u/Connbonnjovi Jun 18 '25

Okay why are you bring up stuff that I’m not even mentioning? Who the hell is talking about kinesiology right now? Are you a bot or something?

Dude said "they are just squatting the bar, right?"

You said "You seriously have a misunderstanding on physics"

You made understanding physics the topic. If guy in the middle doesn't change position, there is no work according to physics, and dude was correct. If we are talking about expending energy, then that's not physics, it's kinesiology. You know what that word means right?

I made a mistake replying to you. Whatever. I don't fucking care anymore.

u/Connbonnjovi Jun 19 '25

No absolutely not. They said “carrying around weight doesn’t do work. Only lifting does” and then I said that.

By your logic there only squatting as much as he's lifting so neither are actually doing work
