Offensive moves can help to increase your chances of knocking out an opponent and keeping him down long enough to win, so learning those moves are important, but many times, the defensive movements can win your match. If the boxer can avoid punches from the other fighter, it helps to maintain his longevity and stamina throughout the match. Below are some of the techniques used with defensive boxing such as the bob and weave, the slip, the cover-up, and the parry/block.
The Bob and Weave: one or the most common seen techniques in boxing is the bob. This is when the boxer moves his head into the position the helps him to duck an incoming punch. The boxer will shift their body and quickly bend their legs to the right or left to avoid contacting the punch of the opponent. After the punch is missed, the boxer uses the weaving motion to come back to an upright position.
The Slip: slightly rotating the body when a punch is incoming is what slipping is. Doing this motion will cause the punch to go past the head without making a connection. When the punch gets close, the boxer will rotate his shoulders and hips in a sharp movement. This results in the chin being protected as the punch goes past the opponent.
The Cover-Up: covering up is typically a last resort for the fighter when their face or body is not protected. This involves the fighter holding their hands high up in from of their chin and head. If their body needs protection, they will tuck their forearms against their torso. Both fists are pressed together in front of their face to achieve head protection. This is a really poor method of protection to get out from under the attacks.
The Parry/Block: When a boxer uses their hands to defend themselves from an array of punching attacks, this is called the parry/block. The boxer uses their open hand, as a punch comes near, to send a quick blow in a lateral motion to the forearm or wrist of the opponent to redirect the punch.
These defense techniques are all important in keeping the boxer from becoming victim to the onslaught of punches from their opponent, thus keeping them in the ring longer and increase their chances for a win.
