I just saw a video of Ronnie over in Korea back in 03 I think, he was fairly lean and they measured his arm at 21.6 inches. I think that shows that Anthony is exaggerating. His arms were never bigger than Ronnie's.
ive seen melvin in person.... and yes his arms are massive....ill post a pic when i get home
Not the waist though, on a 280lb man a 33-34 inch waist would look tiny.
