So a decently built kid with no bodysuit is squatting 600 pounds.
Yet, you have these powerlifters who are tub of lards, bellys hanging over their waist, wrapped up like mummys, wearing a bodysuit, outweighing this kid probably by 200+ pounds, yet not deadlifting much more than this kid.
It might seem like you have a point, but then, to those who have knowledge of such things, it's clear you're not one of them.
HTH
P.S. This guy is a seriously impressive puller. No doubt.
