Back Fist Strike. With the hand shaped in a fist, the impact point of a back fist strike is the middle knuckle on back of the fist at base of the second finger. This pointed joint has a very small impact area that makes it a deadly weapon when it is used against a target such as the thin part of the skull at the temple.
- Stand in a front stance with arms held in the basic guard.Trailing arm will perform the strike.
- Cross arms tightly, one over the other, so one elbow is over the other. Trailing arm crosses on top, with knuckle side of fist touching the ear. Leading arm crosses on bottom with palm side of the fist facing forward. As the trailing arm crosses to the leading side, the shoulders and hips twist toward the leading side to chamber them.
- Step forward into a front stance.
- Just as the foot touches the floor, the upper arm strikes forward in front of the body and then outward as it extends.
- Just as stepping foot touches the floor, the arm snap-twists its fist outward so palm is inward at the point of focus and the shoulders and hips snap back to the front adding power to the strike.
- The middle knuckle on back of fist moves inward striking the point of focus horizontally. As the striking arm is moving outward, the other arm chambers to its hip with the palm side upward. The uncrossing action of the arms creates a push-pull action to increase the power of the strike.
