Brazilian Jiu-Jitsu (BJJ) is a sport martial art system that focuses on ground fighting. Brazilian jiu-jitsu was formed from Kodokan Judo ground fighting (Ne-Waza) fundamentals that were taught to Carlos Gracie by master Mitsuyo Maeda. Brazilian jiu-jitsu eventually came to be its own art through the experimentations, practices, and adaptation from the Judo knowledge of Carlos and Helio Gracie, who then passed their knowledge onto their family.
BJJ 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) or self-defense. Sparring (commonly referred to as “rolling”) play a major role in training, and a premium is placed on performance, in relation to progress and ascension through its ranking system.
