Flex doesn't look very good.
Sure, he's put on muscle, but the whole package looks shitty. For his age he looks quite good, but then again, a boatload of guys his age could and do look every bit as good, and better, than Wheeler.
It's called drugs and above-average genetics.
(Concerning his hams, a couple posters suggest he's oiled them. Dumb. They appear as they always did.)
I honestly think very few here have eyes for bodybuilding. Wheeler really doesn't look anywhere near top-flight status.
