UFC Gym’s instructors thumb their noses at the suggestion that fighting has no place in public. They happily subvert this social convention, leading students through safe and noncontact fitness classes inspired by the pugilistic arts. Each boxing, kickboxing, or group MMA class is lead by a professional fighter, who teaches basic skills during the up-tempo, one-hour workouts. Students warm up with plyometrics before strapping on 16-ounce gloves and hitting a heavy bag with combination of kicks, knees, and elbows. Classes may burn between 800 and 1,000 calories per session, improve coordination and stamina, and increase your tolerance for listening to the theme from Rocky IV on repeat.
