This is the scenario: a guy, say age 21, becomes serious about gaining muscle. He’s 5′ 10″, 7″ wrists, 9″ ankles, average genetics for muscle size-and-proportioned. He’s played sports, but never done more than an occasional resistance workout. Now, he begins a good training-eating-and-resting program. With his genetics, he has the potential for naturally gaining 45 pounds of lean mass if he stays consistent with progressive training/proper eating for a continuous 3 to 4 years.
But, about three months after beginning his training, he starts taking steroids. He does three steroid cycles in the following 18 months, and includes proper post-cycle therapy. That entire time, he’s continuing to consistently train and eat properly. Before the end of two years, he’s gained 45 pounds of lean mass (which with steroids, by the way, is not necessarily typical but neither improbable). At that point, he permanently quits using steroids, but he does continue properly training and eating for another two years. At the end of four years, he carries the same 45 pounds of lean mass.
Arnold’s off screen life has been much more interesting. In short, he took up politics, became the Governor of California and then got caught up in a sex scandal that cost him his marriage and garnered him a son. That is pretty shocking. It would seem that Arnold’s life off the screen, ever since his film career went on hold, has been more publicized. To top it all off Arnold let down his “guard” on the beach a few times. Some very unflattering pictures surfaced online proving Arnold’s muscles have been beaten badly by the giant stick called old age.
