Brazilian Jiu Jitsu
is a self-defence, martial art and combat sport based on grappling, ground fighting, and submission holds. BJJ approaches self-defense by emphasizing taking an opponent to the ground, gaining a dominant position, and using a number of techniques to force them into submission via joint locks or chokeholds.
