left jab - right cross
The one-two often heard. It is the essence of coordinated hand movement and the beginning of punching combinations. The jab acts as the lead punch to the chin and sets up power punches such as the cross, hook and uppercut in rapid succession.

As with all punches, the back remains straight at all times. The legs bend slightly at the knee. Never lean forward with a punch.
