I've been with Serra BJJ in East Meadow, NY since Oct. of last year. Pretty good work out and self defense techniques IMO. I'm 38 already and I feel that I'm in much better shape than when I was in my 20's. I'm a HUGE MMA fan and love the art of BJJ. I completely disagree with brunotheboxer. MMA practitioners certainly have an edge over street fighters (i.e. Tank Abbott, where is he now? ) Good luck in your training joyriide.
BTW, I still have the wheels I bought from you.
