I take an MMA class (UFC style fighting). I like it because it just doesnt teach you one style. It focuses on Mui Tia, Kick boxing, American Wrestling (not WWE style), and of course Jiu Jitsu.
I tried just taking a Martial art like Kung Fu, and I just didnt really like it. Now Mix Martial arts is the future, you know how to fight on your feet, in the clinch, and on the ground.
Just like hornett33 I have lost 20lbs and i just started 6 months ago and that is doing it on and off.
Here is the place I go to
http://www.hackneyscombat.com/ If you ever watched UFC the guy that runs the place is Keith hackney. If you remember the early days of UFC he took on a 650lbs black guy and broke his hand over the dudes head knocking him out. Also If you watch the Ultimate fighter 4 on spike one of his projects were on the Ultimate fighter 4. His name is Gideon Ray.
But if i was looking for a martial arts place i would be looking for an Mix Martial arts place, Or a place that Teaches Mui Tia, and Jiu-Jitsu.
