Straight Leg Kick, or Stretching Kick. As the name implies, the knee should not be bent when doing Ahp Cha Ohl Ki. This kick should be executed from offensive or defensive stance, by bringing the trailing leg straight up to maximum comfortable height. It should be noted that as students progress in flexibility, they become easily capable of breaking their own noses with this kick. It is therefore advised that the practitioner attempt to bring their knee/shin up to their shoulder as opposed to their face. Ahp Cha Ohl Ki can be used as part of a dynamic stretching routine before Mon Puhl Ki.
