By today's standards, Arnold had weak hamstrings, traps, and lats. However, think if we could bring him in his 1975 condition into 1995. Can you imagine how fast those "weak" parts would come up? lol
Arnold on high dose GH = scary muscular growth
Arnold + HCG = Ruhl like mass
Arnold + insulin = insane growth
Arnold + synthol = haha should we even go there?
