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 fundamentals that were taught by a number of Japanese individuals. Brazilian jiu-jitsu eventually came to be its own defined combat sport through the innovations, practices, and adaptation of judo.
Brazilian jiu-jitsu is founded on 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. Brazilian jiu-jitsu training can be used for sport grappling tournaments and in self-defense situations
