Currently, I do weight training, running, boxing, muay thai, and brazilian jiujitsu. I've also recently taken an interest in rock climbing, although I only do it once a month.
As far as competing goes, I suck. Every sport I've tried out for, I either didn't make the cut, or ended up being dead last. I've just started to do sparring in boxing, and I've been making vast improvements, so I might just change that one day.
