I red that Krav Maga is a mixture of other martial arts. If so which are the Martial Art forms that were combined to form Krav Maga?
Yes. It is a mixture of Western boxing punches, Karate kicks and knees, Greco-Roman wrestling, Brazilian Jiu-jitsu ground fighting, Jiu-jitsu throws and grappling, Judo, Aikido and most importantly, “bursting,” adapted from Wing Chun.
Krav Maga is not a martial art. It is a self defense system that has acquired or adapted techniques from different martial arts to fulfill a specific purpose. Those include groundfighting, stand-up fighting and weapon techniques — one can argue form which art actually ex. BJJ, Muay Thai whatever — but always striving to have the most effective one for the current situation for the needed distance, even modified if needed like the vertical punch (with burst).
