Gracie Jiu-Jitsu is a martial art developed by the Gracie family in Brazil. It focuses on ground fighting and submission grappling, emphasizing techniques that allow a smaller person to defend against a larger opponent. The practice includes joint locks and chokeholds, making it effective for self-defense. The art is rooted in traditional Japanese Jiu-Jitsu but has evolved to prioritize leverage and technique over brute strength. Gracie Jiu-Jitsu is often taught in a structured curriculum, with students progressing through belts as they gain skills and knowledge. It has gained popularity worldwide, influencing mixed martial arts and self-defense training.
