I work out quite a bit. I find it relieves stress and there are other benefits too. Less people wanna fuck with you for no reason and you get more attention from the girls. I get dirty looks all the time from skaters who don't know me, because they assume I'm some kook who doesn't actually love skating. I couldn't give a fuck though. I just do whatever makes me feel good about myself. Skateboarding will always be first to me, but lifting shit can be fun too. Some people are still stuck in that highschool mentality where they have to label people, and everyone has to be a walking stereotype.
Just for the record, most people who go to the gym are pretty nice people, who will spot you, act supportive, etc. Most of the douchebags are young kids who don't know any better. I don't have a problem with people who like sports/work out, etc; but with people who have a shitty attitude.
