The Brazilian Jiu Jitsu or also called "BJJ" whose major school is Gracie Jiu-Jitsu, is a martial art of Brazilian origin derived from the methods of Judo and Jiu Jitsu imported from Japan to Brazil by Mitsuyo Maeda in the year 1920. It was then developed by the Gracie family. It is a modern and ever-changing martial art. Although not widespread in Europe, it is popular in the United States, Brazil and Japan. The Brazilian Jiu Jitsu is characterized by a traditional ground struggle with the wearing of a keikogi (regularly called kimono in Western countries). Each method of finalization is either a constriction or an articular key performed on the shoulder, neck, elbow, wrist, hip, knee or ankle.

The Brazilian Jiu Jitsu promotes the principle that an individual can defend himself against a heavier and stronger opponent by using appropriate methods, specifically by bringing ground combat and setting up strangulation methods, joint keys or muscle compression. In contrast to most martial arts that highlight standing combat, hand and foot, it focuses more on ground combat, a fairly technical sector and where the corpulence of people comes into play less.
