I train Brazilian Jiu Jitsu. I coach my schools teen no gi competition team and compete in both Gi and No Gi competitions. I've done a little mixed martial arts, but I really don't enjoy it as much, so I just stick to BJJ.
I've trained in some other martial arts and still train muah thai, although that's just for fun and I don't compete, or have a desire to compete in it.
I love all things automotive as well, I sold my bike when I left for basic training but just haven't gotten around to getting a new one. But I do have a 2012 Subaru STi if you are into tuner cars
