Technique #2: Mantis Accepting Hands with palm push
Victor Jordan has grabbed Sifu Winokur's left wrist with his right
hand preparing to punch with his right.
Sifu Winokur will step his right foot out 45 degrees to the side (Y-Step)
at the same time turns his left wrist palm up and places his right palm
on attackers arm halfway between elbow and shoulder. (Note: You
could break or jar attacker's elbow with this move.)
Sifu Winokur with his right hand palm, strikes the back of their arm
or push them as you turn your feet to horse stance (feet apart shoulder
distance) facing them. Striking here will cause pain and you will free
yourself from the attacker's hold.
Hold tightly with left hand on attacker's wrist. Victor (attacker) has lost
his balance and has moved slightly forward. Slide your right hand up
and grab attacker's shoulder for better balance. Raise your right knee
and strike either the back of the leg (hamstring) or the side of the thigh
(between hip and knee.) This will cause extreme pain if you strike too
hard. Follow up with a side kick to back of attacker's knee to push them
to the ground. Or pull them backwards and sweep their right leg and they
will fall on their back.
