Brazilian Jiu-Jitsu is a martial art that uses grappling techniques like holds and throws. It focuses on ground fighting, meaning that the fighters stay close to the ground and use their bodies and limbs (like arms and legs) to control and defeat their opponent. Jiu-Jitsu is all about using bodyweight and leverage, so even a smaller person can defend and defeat a bigger, stronger person if they know the right techniques. Jiu-Jitsu can be used for self-defense, sport, or to learn the skills you need in mixed martial arts (MMA).
