Cardio and coordination in one! Jab, cross, hook and uppercut. All controlled and wrist friendly. * A jab is a short punch * A cross is a longer straight punch * A hook circles around from the side * An uppercut is a punch from underneath Keep the punches short and snappy! Three rounds are sufficient to start. You can either do one arm at a time, or alternate arms: Jab left, jab right, cross left, cross right, hook left, hook right, uppercut left, uppercut right.
