He has a godawful structure for bodybuilding. The most he could hope for is to look like a smaller version of Rhino. Anyone with eyes can see that.
Adonis would make a much better powerlifter. I would give him a 430 bench, a 670 deadlift, and a 550 squat if he started juicing hard. Not exactly world class numbers for a 240 lb guy, but still good enough to win a few local meets.
