Step by step instructions
From a fighting stance with right foot forward and arms on guard, step left foot into right heel, rotating left heel forward. Raise right knee to the chest, flexing foot.
Extend right leg out on a diagonal (aim to the right corner of the room) as if striking your opponent on the side of the head with your heel, and trace a semi-circle with the foot as knee bends and heel draws back in toward hip. Step right foot down to return to starting position.
