MVKS Kenpo Technique of the Month

As hands start to apply hold:

Step to 9:00 with left into a modified horse stance as you deliver 2 inverted vertical punches to the face and then drop elbows down.
Slide left foot back into a horse stance as you punch to the ground with both hands.
Pivot to a right rear bow stance and then deliver a right rear scoop kick to the inside of the opponents' knee, a right side kick to the inside of the opponents' other knee, scrape down the front of the opponents shin and deliver a right front stomp kick to the opponents' foot.
Pivot to a left rear bow and repeat the above kicking sequence with the left foot.
