Self defence

Self-defense techniques and recommended behavior under the threat of violence is systematically taught in self-defense classes. Commercial self-defense education is part of the martial arts industry in the wider sense, and many martial arts instructors also give self-defense classes. While all martial arts training can be argued to have some self-defense applications, self-defense courses are marketed explicitly as being oriented towards effectiveness and optimized towards situations as they occur in the real world. Many systems are taught commercially, many tailored to the needs of specific target audiences (e.g. defense against attempted rape for women, self-defense for children and teens). Notable systems taught commercially include:
