Help me find an athletic hobby I'm in college and I'm outta shape. I run on treadmills sometimes. I don't like sun exposure. Team sports are fun, but it doesn't have to be a team thing. I'm a weakling so I'm kind of hesitant to play indoor soccer (ow my head/shins) or volleyball (ow my forearms). I've done martial arts before so I'm not really interested in doing it again at the moment. Suggestions?
