What is the main cause of the difference in shoulder size/shape in this picture?

Bump because I can't figure it out either. Might just be posture.

I think it's just skeletal build

It that picture almost purely posture
The guy on the right has his shoulders rolled forward as he hunches over
The guy on the left has neutral positioning with his left arm pulled up

They kept mentioning creative and steroids in this video. Wonder if they browse Veeky Forums. But to answer you question, it's probably FRAME

It's like that for the whole video. It's odd that the guy who lifts more has worse posture. But on the other hand, why is it bad posture if it makes you look better.

Because when you hunch over with your arms in front of you like that it emphasizes the front delt
and the lateral delt pops up behind it because your back isn't keeping it pinioned back in a neutral upright position
Try it for yourself by pushing your shoulders as far forward as you can then pin your scapula back like you're setting up for bench
That's the difference
It's also why bodybuilders do the pose where they hunch over and flex to give a better view of the whole deltoid chain into their traps

James was talking about his back being fucked up, so probably posture.

they have answered questions from some board before,so maybe one of them does, probably Lawrence, fucking nerd.

What's FRAME?

skeletal structure

bruce and james right?

Unsubbed when they switched to roosterteeth though, felt too different

But skeletons of the same height are virtually indistinguishable, even sex is hard to tell. And female roid monsters have a better v taper than the biggest natties.

Guy on the right definitely has a broader frame. He also lifts and has pretty juicy shoulders

It's literally the same.

mainly bad posture on the left

How many skeletons and accompanying non skeleton versions have you seen to judge this?

Dude on the right has a broader frame

I believe most of them to an extent. They're also probably linked to anything funny about them by fans.
