KRAV MAGA
Famous practitioners: Liam Neeson in Taken, Sam Fisher (Splinter Cell), Daniel Craig, Jennifer Lopez in Enough
There are no rules in Krav Maga. It’s not regulated by any traditional governing body, it doesn’t require uniforms, and its no-nonsense name means “hand-to-hand combat.” The eyes, jaw, throat, and groin are all fair game — in fact, they’re primary targets. But if you think that sounds like girl fighting, think again: It’s the discipline of choice for the Israeli Defense Forces, who you may have heard occasionally experience some trouble. And the International Krav Maga Federation trains some of the world’s top bodyguards, using Krav Maga exercises to teach them how to evacuate VIPs through hostile crowds. So if you’re looking for a no-frills, all-business method of self-defense that isn’t a glock, Krav Maga is for you.
