Colin’s idea of using the biomechanics of specific techniques and sequences in kata/hyung/tul shows an insightful understanding of the martial arts…His approach to using the underlying principles of movement in forms introduces sheer endless possibilities for techniques. I would even say this brings back the “martial” to the “art.”
