A front kick in Taekwondo, and other Martial arts, somewhat literally translated from the Korean ap chagi is widely regarded as the simplest possible Kick. It is executed by lifting the Knee straight forward, with the part of the Leg below the knee hanging fairly straight down, and then straightening the knee quickly so that the leg straightens out in front of the practitioner. It is by most instructors considered important, although not always taught; that the leg should also be pulled back immediately after the Forceof the Kick has been delivered.
