Unlike most other martial arts, jiu-jitsu involves no spectacular throws and kicks and no ceremonial bows. Unlike boxing, it has no punching. And unlike virtually every other fighting technique, it does not rely on brute strength. Brazilian jiu-jitsu is a form of self-defense that takes place almost entirely on the ground although its falling techniques from a standing position are a distinctive mark among competitors. Fighters use snakelike grappling moves to choke their opponent, or, with the weight of their entire body, they press against key joints, bringing them close to the breaking point.
