I actually saw him at my gym a few months ago. He was in town for a promotion for one of the supp shops.
The guy's about 5' 7" or so, had to have been 250 at the time. I'm 6'1", 220 and I towered over him. But his arms are damn near as big as my legs. Looked like he could tie me in a knot if he wanted to. Never seen anything like him.
