Brazilian jiu-jitsu

Brazilian Jiu-Jitsu is a martial art and combat sport based on ground fighting (ne-waza) and submission holds. It focuses on the skill of taking an opponent to the ground, controlling one's opponent, gaining a dominant position, and using a number of techniques to force them into submission via joint locks or chokeholds.
