Brazilian Jiu-jitsu (BJJ) is a martial art that originates from Brazil, with its technical roots in Judo. BJJ focusses on taking the fight to the ground, and submitting the opponent by joint-locks or chokeholds. By taking the fight to the ground, and using the proper technique and leverage, practitioners are able to defeat larger and stronger opponents.
A large part of BJJ is live sparring, often called rolling. During rolling both participants try to submit each other, simulating a real life situation with a resisting opponent. Because of the ability to spar at full intensity, the competition and sports aspect is a large part of BJJ.
