You may not think that it is possible for a small women to take down a male over six feet tall, but it can be done. Self-defense is not always easy, the main message in self-defense is that once the attacker is unable to attack for whatever reason, you should make a quick escape. The whole purpose of showing self-defense techniques is to give the one being attacked the chance to escape not to remain and fight his/her attacker. It should also be known that self defense is not only for women. Men also need it as well as children.
You can call Sensei Robert Myers for more information if you would like to set up a self defense seminar/class for women, men or both depending on the request.
