Target Areas of the Body
The primary target areas are the aggressor’s head or other exposed extremities.
~ From the basic warrior stance, raise the knee of your right foot above waist level. Your right leg should be bent at approximately a 90-degree angle. Shift your body weight to your left leg to maintain your balance.
~ Forcefully drive the flat bottom of your right boot or the cutting edge of your right heel down onto the aggressor. At the same time, bend your left knee slightly to drop your body weight into the strike.
~ Rapidly return to the basic warrior stance.
