I would like to get into some form of MA training routine, not only for the self defense aspect but also to offer up something different in the general fitness routine. Cardio and gym get old and boring for me. I have tried BJJ, but according to my orthopedist if I want to keep training he is going to have to do some cutting which is something that I would like to avoid. Anything out there that is maybe easier on the ole joints for us broke-ass fogies? I'm working the PT routines to get the joints stabilized and the surrounding areas strengthened up, but after that I'd like to try adding some defensive arts into the mix. Any thoughts?
