I have a brown belt in Taekwondo and a green belt in Shotokan Karate. I took professional boxing lessons for about 7 months and trained under a professional ex Muay Thai Kickboxer for around a year and a half. I've had about maybe 20 Aikido classes and several Jeet Kune Do Classes as well (although I swear it was Wing Chun). I did all this before I found out about Jiu JItsu and gave up all of that for Jiu Jitsu back in February of this year. Focusing on Jiu Jitsu is all that matters now.
