I took my first Krav Maga class the other day. It was fun, albeit a little simplistic. I have a background in Japanese jujitsu, and many martial art forms and self-defense classes borrow from Japanese jujitsu in some form or fashion. Krav Maga is no different. The names for stances and defenses may have been altered, but the techniques are similar, if not the same ones that are found in Japanese jujitsu.
