Defending against a foot or knee in your back.

1. This type of street attack is more common if there is more than one attacker. That is why it is important to be able to escape quickly.
2. Since it is very difficult for the attacker to move backward very easily on one foot, the defender must drive backward very quickly with a burst of energy. You want to take a couple of very quick steps as you twist your body to one side to turn to face the attacker.
3. Continue twisting as you move toward the attacker. Notice how I am starting to cock my hand back for a palm strike as I am twisting.
4. Deliver the palm strike and continue your attack until the threat has been nullified. Notice that I am already striking with my palm heel before the attackers foot has even reached the ground in this video footage.

Immediately follow up with basic palm, knee and elbow strikes until the threat is gone and you can run to safety.
