What's better than Tae Kwon Do?
So, I have a first-degree black belt in Tae Kwon Do, but I have not participated in the sport for nearly 8 years. I am interested in getting "back into the game", because I have never been faster than I was during my TKD training, but I'm not so interested in re-learning TKD. What other martial arts (or fighting styles) do you suggest that would A) allow me the wheels/flexibility that I had during TKD, and B) be more applicable in self-defense/fighting than TKD is?? Thanks for your input!
