There’s a lot that I could say, but having gone from being your typical scrawny nerd to decently muscular, the single biggest thing has been a massive boost to my own self-confidence. While I wouldn’t say I ever actively disliked it, I had no idea how good it would feel to look of myself in the mirror and actually be happy with what I see. That in general has had pretty huge effects on me socially. I’m a lot more outgoing, dating is way way easier (disclaimer: am gay, and men are pigs), and I just generally find it a lot easier to connect with others now that I’m not constantly doubting myself.
