Brazilian Jiu-Jitsu (BJJ) techniques focus on grappling and ground fighting. Practitioners use leverage and technique to control opponents, often emphasizing submissions, joint locks, and chokeholds. These techniques allow smaller individuals to defend against larger opponents effectively. Key BJJ techniques include guard, mount, and side control. The guard position allows a practitioner to defend while on their back, while the mount provides a dominant position on top. Submissions, such as the armbar and triangle choke, are essential for finishing an opponent, showcasing the art's strategic depth and effectiveness.
