Boxing, or pugilistics, is a tactical martial art where ring insight, coordination of feet, eyes and hands, and fitness are central. Two opponents try to score points by hitting each other on the right hits, or winning on a knockout (KO, for example). This can be achieved by single shocks or a combination of different shocks, the direct impact, the uppercut and hook. Power is needed as much as pure speed to hit an opponent both quickly and hard. In addition to traditional men's boxing, women's boxing championships are also held. Here is the list of world's greatest boxers of all time.
