I been doing the DRAGO MMA program this is some intense material. I first study Kenpo, then I went into Kickboxing, then I learn some of the Krav stuff, but I really am sticking with the DRAGO MMA program. His drills are very intense, plus his layout of a classroom instruction flow, I mean next thing you know its been 1 hour and 20 minutes and you are sweating like a dog and you feel like everything you just learned will be usable.
check him out Bruce Drago
its well worth it. PEACE
