Brazilian Jiu Jitsu
A self-defense martial art and combat sport based on grappling, ground fighting, and submission holds. BJJ 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. BJJ revolves around the concept, taken from traditional Japanese jūjutsu, that a smaller, weaker person can successfully defend themselves against a bigger, stronger, heavier opponent by using leverage and weight distribution, taking the fight to the ground, and using a number of holds and submissions to defeat them. BJJ training can be used for sport grappling and self-defense situations. Sparring, commonly referred to as "rolling" within the BJJ community, and live drilling play a major role in training and the practitioner's development. BJJ can also be used as a method of promoting physical fitness, building character, and as a way of life.
