Most Sports Styles call this the Inside Block, though it is also refered to as an Outside Block
Charlie grabs my lapel and I, in turn, grab his wrist.
Stepping backwards to a Back Stance, I coil my body pulling Charlie off balance and straightening his arm. Also my right arm perpares to strike.
I fire my hip by snapping my front leg inward. Then I follow with a strike to pressure point TW-12 on the back of the arm breaking the elbow capsule.
An alternative to the arm break is striking pressure point TW-17 just under the ear.
