Brazilian jiu-jitsu (BJJ) is a martial art that focuses on ground fighting and submission grappling. It teaches practitioners how to control and submit opponents using techniques like joint locks and chokeholds. BJJ emphasizes technique over strength, making it accessible for people of all sizes and skill levels. The art originated in Brazil in the early 20th century, influenced by Japanese jiu-jitsu. It gained popularity worldwide, especially in mixed martial arts (MMA) competitions. BJJ not only improves physical fitness but also builds confidence and discipline, making it a valuable practice for self-defense and personal growth.
