There are four widely recognised boxing styles used to categorize boxers. The swarmers, out-boxers, sluggers, and boxer-punchers are among them. These categories are not hard and fast rules, as not every fighter follows them, but they are a good starting point for discussion. The four styles are based on how a fighter uses his hands in a bout. Swarmers are fighters who use their fists and feet equally well and will try to land as many punches as possible while moving around their opponent. They are difficult to stop because they don't rely on one particular technique or strategy but rather make each fight unique. Some famous swarmers include Jack Dempsey, Joe Louis, and Muhammad Ali. Out-boxers focus solely on punching above the belt line, using their arms to block enemy attacks while taking advantage of openings in their opponents' defenses. Out-boxers usually have strong legs and good footwork because they need all their energy for throwing punches. Some great out-boxers include Benny Leonard, George Foreman, and Mike Tyson. Sluggers go after the body as well as the head. They use hooks, uppercuts, overhands, and other powerful blows to the abdomen, chest, and shoulders.
