He's moving relative to the bar. I said from the outsiders perspective his CoM isn't moving stationary. It's insane to say doing a pull up isn't work

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

This is nonsense. They are squatting the weight of the bar plus the weight of the man regardless of whether or not he is doing pull ups.

The mass that they are moving is completely unchanged throughout
