MMA (As a HOBBY and for the workouts, guys, I am under no delusion that I might step in the cage for real one day).
Shotokan & goshinjitsu karate. It is not neko-ryu goshinjitsu, I don't know WTF it is. My sensei calls it American freestyle, and I'm thinking, whatever, just help me with my skillz.
I also took TKD for four years and got to advanced green belt in that.
