Brazilian Jiu-Jitsu (BJJ) is a martial art and combat sport that focuses on ground fighting and submission grappling. Developed from traditional Japanese Jiu-Jitsu and Judo, BJJ places a strong emphasis on positional control, leverage, and submissions to overcome opponents. Practitioners, known as BJJ practitioners or grapplers, aim to submit their opponents through joint locks or chokes. BJJ is often practiced both as a self-defense system and as a competitive sport with tournaments held worldwide.
