In-Fighting is a form of boxing that involves a fighter who attempts to overwhelm his opponent by applying constant pressure. In-Fighters tend to have a very good bob and weave, good power, a good chin, and a tremendous punch output (resulting in a great need for stamina and conditioning). Boxers who use the In-Fighting style tend to have shorter careers than boxers of other styles. Sustaining the adequate amount of training required to execute this style is nearly impossible throughout an entire career, so most In-Fighters can only maintain it for a brief period of time. This inevitably leads to the gradual degradation of the ability needed to perform the style, leaving the fighter open to increasing amounts of punishment.

This style favors closing inside an opponent, overwhelming them with pressure and flurries of hooks and uppercuts. They tend to be fast on their feet which can make them difficult to evade for a slower fighter. They also tend to have a good "chin" because this style usually involves being hit with many jabs before they can maneuver inside where they are more effective. Many swarmers are often either shorter fighters or fighters with shorter reaches, especially in the heavier classes, that have to get in close to be effective. Tommy Burns was the shortest Heavyweight champion at 5'7, while Rocky Marciano had the shortest reach at 67-68 inches. However, heavyweight Jack Dempsey (a modern cruiserweight in size) at nearly 6'1 in. tall with a 77 in. reach was an exception to the rule.

Famous swarmers in real life include:

Strengths and Weaknesses

Some In-Fighters are able to observe their opponents to memorize the movements and rhythms of their boxing style so that In-Fighters can attempt to turn the match around with their heavy Jabs, Hooks, Straights, and Uppercuts. The spring in their knees help absorb the punches their opponents throw at them. But even In-Fighters need the support of their leg strength to keep moving. If their opponents land shots to the body, their rhythms are taken down. In desperation they try to bring fights to an In-Fighting brawl. This is then a test to see which man has the most endurance in holding their breath.

Peek-a-Boo Style (Form of In-Fighting)

Peek-a-Boo is a boxing style where a fighter's hands are placed in front of a boxer's face, like in the baby's game of the same name. It offers extra protection to the user's face and makes it easier to jab the opponent's face. Peek-a-Boo was developed by the legendary trainer Cus D'Amato.

Peek-a-Boo boxing utilizes relaxed hands with the forearms in front of the face and the fist at nose-eye level. Other unique features include side to side head movements, bobbing, weaving and blind siding your opponent.
