Farm boy genetics
if jay could go back in time, I think he would go back to 1963 and ask Ronnie Coleman's parents not to have sex that night so that decades later, he woudln't have to lose so many Olympia titles to him.
I wonder if he regrets starting steroids at such an early age, as it most certainly contributed to his height(or lack there of).
Went from being an athlete to a bodybuilder.
