punch is a striking blow with the fist. It is used in most martial arts and combat sports, most notably Boxing where it is the only type of offensive technique allowed. In sports, hand wraps or other padding such as gloves may be used to protect athletes and practitioners from injuring themselves.

The use of punches varies between different martial arts and combat sports. Styles such as Boxing or Russian fist fighting use punches alone, while others such as Kickboxing, Muay Thai, or Karate may use both punches and kicks. Others such as wrestling and judo (punches and other striking techniques, atemi, are present in judo kata, but are forbidden in competitions) do not use punches at all. There are many types of punches and as a result, different styles encompass varying types of punching techniques.
