So, I have a decent background in martial arts, nothing too useful, Hapkido, Aikido, and Tae Kwon Do. I want to train Jujitsu/judo, I've found a good school and an instructor who seems to be very good. My problem - I'm in my early 30s. I have a rotator cuff injury and an anterior deltoid injury. Both from climbing. I do not want to fight MMA, I just want to learn these styles. I'd say my life mostly revolves around climbing. For people for whom that is unfamiliar it means I like climbing vertical rock walls and peaks. While most of what I do is footwork a good injury from training could keep me from climbing which would suck. When I say my life revolves around it I mean it, I climb on a regular basis and try to get to international peaks whenever possible. What do you think? I'm not going to become a fighter but want to learn the styles but also don't want to stop climbing. How likely am I to worsen my present injuries and really screw myself if I try to take up Jujitsu with a good school?
