A roundhouse kick (also known as round kick or turning kick) is a kick in which the practitioner lifts the knee while turning the supporting foot and body in a semicircular motion, extending the leg striking with the lower part of the shin and/or the instep (top of the foot). The ball of the foot can also be used to strike the target and is preferable when power breaking thick boards. This type of kick is utilized in many different martial arts and is popular in both non-contact and full-contact martial arts competitions. The kick has many variations based on stance, leg movement, striking surface, and the height of the kick.
