I'm interested in pursuing some type of martial arts as a path towards fitness, discipline and possibly self defense (listed in order of importance to me). I took Tai Chi a number of years ago but didn't feel it was right for me. I know there are numerous types of martial arts i.e. Tae Kwon Do, Karate, but I'm not sure where to start. My friend takes cardio kick boxing (in another state), but I'm not sure I'm up for that. My ideal body weight is about 35 lbs. away and I'd love to find something physical that is more meaningful to me than aerobics, for instance. Anyone out there with experience?
