He does the MMA which is Mixed Martial Arts. Combination of judo, wrestling, karate, boxing and kick boxing all rolled into one. It's also calle U;timate fighting. No gloves and it's pretty rough, which I am not too happy about, but he enjoys it and is good at it. He went through several other sports through school before he found this. At least I don't have to worry about him getting jumped in a dark alley!
