Someone mentioned martial arts in one of my exercise threads.Does anyone know of any good beginner/self-teaching media for that?I'm thinking for exercise, martial arts is a way of moving, balance, probably better grounding... That idea of not being able to be pushed over sounds interesting. There's got to be some good "grounding," something like that with martial arts.This would be adding martial arts movements into exercise. I'm not committed to martial arts at all. It's exercise to me. And I'm cheap. I'm not getting a teacher or buying anything.
