Since it's something I love doing, I just kinda make time for it, I guess.
I make friends at the gym.
I'm single. My last girlfriend didn't lift or exercise much at all. I liked her for other reasons so, while I wanted her to be healthy, it was never the end of the world that she wasn't into abusing barbells.
I don't ask my family for their opinions on me training. My parents were the ones who originally got me into the gym in the first place, so I'd say they're amicable to the fact that I train -- however when I've told them specific goals they've responded very negatively. So long as I don't tell them what I'm up to, they seem to be fine :/
