Frankly I think bodybuilding is a reasonably bad choice for people who aren’t serious athletes. Nobody I know who is serious about anything non-athletic like having a really serious career or whatever is spectacularly successful in that stuff who I’ve met. Plus it opens one up to all sorts of injuries, eating disorders, mental problems if done improperly. I did some in college and the strongest guys I knew just worked low-level jobs while attaining frankly mediocre academic results in usually somewhat mediocre programs. The most successful mathematicians etc I met were usually tall & skinny and just did walks or sailing or something for exercise or went dancing with their wives.
