If you want something physical and skill-building check out Ohio Krav Maga and fitness: http://ohiokravmaga.com/ More of a gym than a dojo, and somewhat of a community of like-minded folks that enjoy beating on each other. Beyond fighting, there is crossfit, cardio MMA, boxing, BJJ ...A lot of pushing each other to get better. Much more fun and social than when I used to train in more traditional martial arts...
