Krav Maga literally means "contact combat". It is a Hebrew martial art that mostly focues on self-defense. It has varying principles, theories, styles and ideas most probably coming from the idea that the martial art is to be used in real-life situations. Krav Maga was developed by Imi Lichtenfield, a boxer and wrestler who defended their Jewish quarter against fascist groups in Bratislava. The style goes by the no-holds-barred principle since it is developed to be used for street survival. Its includes not only boxing and wrestling techniques but also Karate kicks and Knees, Brazilian Jiujitsu ground fighting, throws, grappling and Wing Chun's bursting.

The concept of Krav Maga is to be able to block or avoid attack and respond at the same time, as opposed to blocking or avoiding an attack then responding. Two actions must be done simultaneously and must target vital areas including the eyes or the groin. It allows headbutts and virtually any objects to be used as a weapon. The weapon may be anything from a dagger to a garbage can. For as long as you can effectively use it to attack or defend yourself, it's considered a weapon. And since the Krav Maga practitioner that the attacker will most probably lash at him with everything he's got, Krav Maga also teaches disarming, disabling and over-all defending against armed attackers. Due to its "realistic" and no-holds-barred approach, Krav Maga has become one of the top martial arts for self-defense.
