I am new to karate and about to check out a school that teaches this style. I'm in my forties and tired or going to a regular gym to lift weights treadmill etc. I also looked at Bjj, judo,samo and don't really think they are for me. Anyway, does anyone train in this style? I am not in that great of shape and the classes meet three times a week for three hours a class. This concerns me. The teacher is in his seventies and I am sure teaches old school. Any input as to the what this style is like and how I might prepare myself would be most greatful.
