Brazilian jiu-jitsu -

Is a martial art and combat sport system that focuses on grappling with particular emphasis on ground fighting.

Brazilian jiu-jitsu was developed from Kodokan judo ground fighting (newaza) fundamentals that were taught by a number of Japanese individuals including Takeo Yano, Mitsuyo Maeda, Soshihiro Satake, and Isao Okano.

Brazilian jiu-jitsu eventually came to be its own defined combat sport through the innovations, practices, and adaptation of judo.

BJJ advocates the concept that a smaller, weaker person can successfully defend themselves against a bigger, stronger, heavier opponent by using 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 and in self-defense situations.

Sparring (commonly referred to as "rolling" within the BJJ community) and live drilling play a major role in training and the practitioner's development.

BJJ is considered a martial art, a sport, a method for promoting physical fitness and building character, and a way of life.
