A strike is a directed, forceful physical attack with either a part of the human body or with a handheld object, intended to cause blunt or penetrating trauma upon an opponent.

A punch is a striking blow with the fist. It is used in most martial arts and combat sports, most notably western 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.
