Arnold = "massthetic". He said it himself in Pumping Iron. If one body part were to get bigger then everything else must grow to match it. But, he never said anything about having a gut like a pregnant pig.
Jay, Coleman, Yate, et al? "ASSthetic", which is to say big for the sake of big. Huge bellies that look like transplanted turtle shells. So out of shape they can barely walk and yet still call themselves "physique athletes".
Coleman crucified his body for relative fame and a small fortune. His personal slide from the Golgotha of his own making is a study in just how stupid a really ignorant man can be. He deserves what is happening to him because he is the author of it all.
And yes, without the drugs none of them would be anything. Including the Oak.
