Brazilian Jiu-Jitsu is a martial art, combat sport, and a self defense system that focuses on grappling and especially ground fighting. The art was derived from the Japanese martial art of Kodokan judo in the early 20th century.It teaches 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. Brazilian Jiu Jitsu 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 the grades/belts.
