Brazilian jiu-jitsu, BJJ, is a martial art, combat sport, and a self defense system that focuses on grappling and especially ground fighting.
Brazilian Jiu Jitsu promotes the concept that a smaller, weaker person can successfully defend against a bigger, stronger assailant by using leverage and proper technique – most notably by applying joint-locks and chokeholds to defeat the other person. BJJ training can be used for sport grappling tournaments (gi and no-gi) and mixed martial arts (MMA) competition or self defense. Sparring (commonly referred to as “rolling”) and live drilling play a major role in training, and a premium is placed on performance, especially in competition, in relation to progress and ascension through its ranking system.
Sport Brazilian Jiu-Jitsu’s focus on submissions without the use of strikes while training allows practitioners to practice at full speed and with full power, resembling the effort used in a real competition. Training methods include technique drills in which techniques are practiced against a non-resisting partner; isolation sparring, commonly referred to as positional drilling, where only a certain technique or sets of techniques are used, and full sparring in which each opponent tries to submit their opponent using any legal technique.
