Brazilian Jiu-Jitsu (BJJ) is a self-defense martial art and combat sport based on grappling, ground fighting and submission holds. It focuses on the skill of controlling one's opponent, gaining a dominant position and using a number of techniques to force them in to submission via joint locks or chokeholds.
BJJ training can be used for sport grappling tournaments and in self-defense situations. Sparring, commonly referred to as "rolling" within the BJJ community, and live drilling plays a major role in training and the practitioner's development. BJJ is considered a martial art, a sport, a method of promoting physical fitness and building character, and a way of life.
