Bobbing is one of the basic strategies of defensive boxing, executed by slightly moving the head to either side so that the opponent's punches slip by the boxer's head. You use the slip to evade swings , jabs, and straight punches. It can not be used with hooks as they move on the side level. Using slips is valid but risky with uppercuts since the punch is usually too close when the defender can determine the exact line of the punch. To overcome the hooks problem, the defender usually incorporate slipping (also called weaving) with ducking (also called bobbing).
Άρα μάλλον σκύψιμο θα έλεγα για το bob, συνδυάζοντας την τελευταία πρόταση του αποπάνω με αυτό από εδώ: Bob and weave –Bobbing moves the head laterally and beneath an incoming punch. As the opponent's 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 opponent's still-extended arm. To move outside the opponent's extended arm is called "bobbing to the outside". To move inside the opponent's extended arm is called "bobbing to the inside". Joe Frazier, Jack Dempsey, Mike Tyson and Rocky Marciano were masters of bobbing and weaving.
