Reverse hand whip fist to shoulder
Once the arms have reached about 90% of full extension, pause, turn the hands palm up, and curl in the fingers to form a tight fist. In a rapid motion, snap the hands up and back down, much like performing a double downward back fist strike. Imagine someone holding your wrists, and as you pull upward, they would instinctively resist, and pull down. In your change of direction, their momentum is added to yours, increasing the speed of this strike. This image is not being put forward as a final analysis, but rather a mental image for what the movement looks like as performed in my school. The idea behind the technique is to escape a grabbing technique, such as a bear hug or frontal choke. Do not let the elbows swing out to the sides, keep them in.
