I've been considering bringing some form of martial arts back into my life. I participated in Karate for 5 years when I was younger, and very much enjoyed the physical activity along with the self-confidence and self-control I built along the way. I'm looking to supplement my body-building and other forms of exercise. What are your thoughts on worthy and constructive forms of martial arts for an adult? I've been reading a bit on Krav Maga, as that seems to be a very popular form these days. Thoughts? Thanks for any responses!
