Bobbing moves the head laterally and beneath an incoming punch. As the opponents punch arrives, the boxer bends the legs quickly and simultaneously shifts the body either slightly right or left. Once the punch has been evaded, the boxer weaves back to an upright position, emerging on either the outside or inside of the opponents stillextended arm. To move outside the opponents extended arm is called bobbing to the outside. To move inside the opponents extended arm is called bobbing to the inside. Joe Frazier, Jack Dempsey, Mike Tyson and Rocky Marciano were masters of bobbing and weaving.
