Dex has exceptional genetics, though. He's an aberration.
That and I believe he was "smarter" with his usage, didn't play the size game and probably didn't "abuse" the shit out of drugs. Still abuse at that level but compared to Coleman, Kai, Phil, who played the mass monster game will burn out sooner or later quickly. Phil better nab as many titles before health and age decline
Dexs longevity proves he slowly added mass over the yrs and if u look when he does his back double bi or front most muscular, he's one of the only few who still has striations all over his delts
