i used to do muay thai as well about 10 years ago. the style that im hoping to start is karate. here is a link to the school if you wanna check it out. http://www.sanyamabushi-goju.com/index7.htmI've only been drumming seriously a couple years but before that I was playing bass in death metal bands while actively training and competing in muay thai kickboxing , brazilian jiu jitsu and mixed martial arts for 10 years. I can say that those arts got me in good shape and I can fight really well, but they don't mesh with drumming in my opinion, especially mma and kickboxing, it's too hard on your hands constantly throwing punches.
Now I'm in a band and stopped all that training even though I love it, because it robs my forearms and calves of stamina and drumming is more important to me now. I am too old to make a living as a fighter, and taking a beating for no$ is not as fun as thrashin the kit!
