Brazilian Jiu Jitsu
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 brought to Brazil by Mitsuyo Maeda (1878-1941), a student of Kodokan Judo with a history of challenging and interacting with other combat arts.
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.
