Brazilian jiu-jitsu

Brazilian jiu-jitsu (/dʒuːˈdʒɪtsuː/; Portuguese: [ˈʒiw ˈʒitsu], [ˈʒu ˈʒitsu], [dʒiˈu dʒiˈtsu]) (BJJ; Portuguese: jiu-jitsu brasileiro) is a martial art, combat sport, and a self defense system that focuses on grappling and especially ground fighting. Brazilian jiu-jitsu was formed from Kodokan Judo ground fighting (newaza) fundamentals that were taught to Carlos Gracie and Luiz França by Mitsuyo Maeda and Soshihiro Satake. Brazilian jiu-jitsu eventually came to be its own art through the experimentations, practices, and adaptation from the Judo knowledge of Carlos and Hélio Gracie, who then passed their knowledge on to their extended family.

BJJ promotes the concept that a smaller, weaker person can
successfully defend against a bigger, stronger assailant by using proper
technique, leverage, and most notably, taking the fight to the ground,
and then applying joint-locks and chokeholds to defeat the opponent. BJJ training can be used for sport grappling tournaments (gi and no-gi) and mixed martial arts (MMA) competition or self-defense.^[2] 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.

Since its inception in 1882, its parent art of Judo was separated from older systems of Japanese ju-jitsu
by an important difference that was passed on to Brazilian jiu-jitsu:
it is not solely a martial art, it is also a sport; a method for
promoting physical fitness and building character in young people; and,
ultimately, a way (Do) of life.^[3]^[4]
