NO WAY Iron Mike pressed 5 bills, not at 200 lbs. or ever, he was a genetic freak no doubt, but 500 is ELITE, ALL UNIVERSE CLASS, he didn't train enough for it when he was younger, he was focused on boxing
A 500 bench takes years of training even with great genetics
405 is out of reach for almost everyone - but 500 ?
COULD he have done it if he trained for it - maybe
