- With feet together, step to your left with your left foot (to 9 o’clock)into a horse. Simultaneously strike to opponent’s groin with your right back hammerfist as your left hand pins opponent’s left arm.
- Have our right foot meet your left foot (forming a close cat stance) and then around and behind opponent’s left leg (between 4 and 5 o’clock)into a right reverse bow. Simultaneously strike opponent’s groin with aright heel palm; then grab opponent’s testicles with a right squeezing claw,
- Pivot into a right neutral bow (facing 4 o’clock) as your right arm follows the contour of your opponent’s body and your right elbow strikes up to his chin.
- Complete your pivot (facing 5 o’clock) into a right forward bow as you deliver a left heel palm strike to left floating ribs of opponent.
- Crushing Hammer serves as a good backup to Captured Twigs in the event you are unable to rotate in attempting to execute Captured Twigs. On the other hand Captured Twigs serves as a back to to Crushing Hammer when you are unable to step to the side.
