Brazilian jiu-jitsu is a self-defence martial art and combat sport based on grappling, ground fighting, and submission holds. BJJ focuses on taking ones opponent down to the ground, gaining a dominant position, and using a number of techniques to force them into submission via joint locks or chokeholds.
