The preparatory position for both kicks is more or less as for the front kick, with the knee raised toward the chest and the foot bent upward. The supporting leg must be slightly more bent. Then, for the back snap kick sharply swing the thigh to the rear and snapping the knee strike the target with the heel. The target is usually the groin or the stomach. For the back thrust kick, push the heel to the target in a straight line, the target in this case being the stomach, solar plexus or face. In both cases, keep your eyes on the target and avoid leaning too far forward. Also, in order to kick with maximum power, be sure to kick straight to the rear and not diagonally.
