Ronnie coleman is probably the biggest bodybuilder to date, although there are people with the same size arms and chest ect as him I.E jay cutler, lee priest. Ronnie coleman has one weakness compared to other top bodybuilders and i think its his calves. my favourite is defo dorian yates. It takes pro bodybuilders all their lives to look like they do, like ged says, diet, sleep, gear, and dedication.
