Ummmmm, he's on drugs, a lot of drugs. Yes, even there as "small" as he may appear to those used to gazing at his more recent turgid with sythol body, Ronnie Coleman is full of drugs in those photographs. His "genetics", like some sort of androgenic/anabolic genie, came from a bottle.
Once that bottle is empty he will deflate. And you know this.
Spend more time on training yourself in and out of the gym, than on wishing you had this clowns "genetics" and you will be on the way to inspiring others. All the best!
