At CKO Kickboxing of Park Slope, you will be burning fat and toning up by punching and kicking a real, hanging heavy bag. The resistance from hitting a hanging heavy bag burns more calories and tones your muscles up faster than if you were just punching and kicking the air. CKO Kickboxing keeps the punches and kicks basic to focus on the fitness aspect of the workout rather than the martial art itself. Since the class is for both beginners and advanced members, it is geared for each member to go at your own pace and build up your pace each class.
