So I’ve competed in various competitions over the years (jujitsu and kickboxing). However I am now 48, and a combination of concussion and joint pain (hands and knees) mean that I have decided to step away from that. but I am still competitive, I still need that as a focus for training, and martial arts has always been the only exercise type I enjoy. So here is my question: has anybody here switched from sparring comps to kata competition or anything similar? Any tips or recommendations?
