Since I like drawing muscles, I often study photographs of bodybuilders. It's something I've been fascinaed with since I was a child. Amazing what can be achieved with training and some chemistry these days. Most people unfamiliar with bodybilding and the extremely grotesque sport it has become these days, simply don't know what's possible.
The man is a legend. Light weight!
Dennis Wolf had one year at the Olympia when he made everyone look silly. I believe this drawing used a photo from that Olympia as a reference. Too bad it went downhill from there for the big guy.
