About the School





Rape Prevention Seminar, February/2007

At this Rape Prevention workshop, you will see in the pictures how these girls learned to fight back and fight back hard. They started out learning some basic strikes on the focus mitts. Strikes like head butts, knees, elbows, finger jabs and a few different kicks. Then we teach them some various scenarios where those types of strikes will work. We reflex train them the best way we can in just a few hours and then the guys suited up to attack and try to take the girls down to the ground or cover their mouths and drag them away. Yes, the attackers actually are fighting back...they are not just going in with their arms extended like a walking punching bag!

Notice in the pictures below, the suit the attackers are wearing. They take quite a beating doing this so we use a motor cycle helmet and some old Fist Gear, which are all made to take the beating and to protect the attacker from all the girls strikes. The girls wear bag gloves so they don't hurt their hands slapping the ear and nose areas of the helmet. And they wear heavy duty elbow pads so they can elbow the head without hurting their elbows against the motor cycle helmet. All the scenario training is so they can go all out randomly at the end of the workshop and unload everything they have learned and trained in against their attacker.
