I'm 6' and almost 230 but I don't look that big. a guy of 5'9 at 230 is massive. I think it was Steve Reeves who said one has to add 10lbs of lbm for every inch below 6' to remain aesthetic, but 15lbs for every inch if one is over 6' (from some baseline, I think 200lbs at 6'). I'm a believer. The leverage factor is a bitch, too. 5'5 squatting 500 is probably doing 30% of the work 6'5 lou has to do to move the same through an equal ROM.
