Out-boxers are known for being extremely quick on their feet, which often makes up for a lack of power. The out-boxer seeks to maintain a gap from their opponent and fight with faster, longer range punches. The out-boxer (out-fighter, boxer) is the opposite of the swarmer. 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. 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. They tend to be fast on their feet which can make them difficult to evade for a slower fighter or are great at cutting off the ring with precise footwork. This style favors closing inside an opponent, overwhelming them with intensity and flurries of hooks and uppercuts. Good power, a good chin, and a tremendous punch output (resulting in a great need for stamina and conditioning). Swarmers tend to have very good head movement in order to get inside.

The swarmer (in-fighter, crowder) is a fighter who attempts to overwhelm his opponent by applying constant pressure - taking away an opponent’s usually superior reach. Many boxers do not always fit into these categories, and it’s not uncommon for a fighter to change their style over a period of time. These are the swarmer, out-boxer, slugger, and boxer-puncher.

There are four generally accepted boxing styles that are used to define fighters.
