Xtreme Kickboxing, Rochester

Kim Murray, the head instructor and founder of Murray's Martial Arts Centers, has been practicing martial arts since 1981. In that time he's mastered both isshin ryu karate and kobu-do and opened three Rochester-area schools. There he teaches adults and kids as young as 3 in the karate classes. Cardio kickboxing classes are also on offer, eschewing some of the philosophy of traditional martial arts classes to concentrate on calorie-burning kicks, punches, and cardio routines.
