Judo used to. I guess that counts as exercise in general, but its a LOT of cardio and "weights" pulling and pushing people around- not to mention throwing them! I wish I weren't on blood thinners though because I probably should not be thrown or come to think of it, the whole wrestling part of judo gets pretty intense. Anyway, I'd get a shower after judo and leave the Y all refreshed and clean and awake and happy.
