Tymyo Ap Cha Ki isn't introduced until Juen Gup Hyung. This kick is performed by lifting the knee of the trailing leg up, similarly to the way you would do it if you were doing Moo Reup Cha Ki: Knee Kick, but with enough force to lift you off the ground. The other leg, which was originally the lead leg, but which is now trailing, comes up in a front kick. It is possible to kick extremely high with this kick without requiring as much relative flexibility of the student, compared to other kicks.
