The Rear Naked Choke is a grappling technique commonly used in martial arts, particularly in Brazilian Jiu-Jitsu and MMA. It involves positioning oneself behind an opponent and applying pressure to their neck using the arms. This choke can effectively restrict airflow and blood flow, leading to a submission if executed correctly. To perform the Rear Naked Choke, the practitioner wraps one arm around the opponent's neck and secures it with the other hand, often locking the grip behind the head. Proper technique and positioning are crucial for effectiveness and safety, making it a fundamental skill for grapplers.
