Decent posing, plus decent training and diet, all he needed... All myths about his bad back and bad conditioning are just crap, back was there and his conditioning in the early 90s was great... Labrada and Taylor in front of him, lol...
What surgeries did he have?
Shoulders, starting in 1995, no cartilage there... Lost a bit of his monstrous width during years because of that, training hard was not easy for him, plus chronic asthma...
