Brazilian Jiu-Jitsu is a self-defense martial art and combat sport based on grappling, ground fighting, and submission holds.
BJJ revolves around the concept, taken from traditional Japanese Jiujitsu, 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 using fighting techniques and submission holds involving joint-locks and choke holds. On the ground, physical strength can be offset or enhanced through proper grappling techniques to defeat the opponents. In other hands, to control and overcome greater size, strength, and aggression with lesser size and strength is the keynote of the sport.
Students of the sport gain a deep understanding of the workings and limits of the human body. The physical benefits of jiu jitsu are immense and well-documented. Because jiu jitsu presents a combination of dynamic and explosive movements with pressure-based isometric pushing, pulling, and holding, it helps to develop increased strength and cardio, as well as promotes weight loss and improved muscle tone.
