Thinking of canceling my gym memebership to join Ohio Krav Maga which offers Krav Maga, Crossfit, BJJ, Muay Thai, and MMA (all inclusive), and doing my lifting for free at DSCC (base) if I need to. Cost dif. is + $60/month. My real concern is the change from traditional weightlifting to Crossfit. I'm 32 now and I would like to feel more "in shape" and not be so sore in all my joints and back anymore, but I like being big. I just don't want to be so lumbering big anymore. Plus, the martial arts is something I've gotten away from for a long time, and now have the time and money to invest into it. Thoughts?
