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 wrapping one arm around their neck while securing the other arm to create a chokehold. This technique can effectively restrict airflow and blood flow, leading to a submission. To execute the Rear-Naked Choke, the practitioner typically sits or kneels behind the opponent, using their legs to control the opponent's body. Proper technique and positioning are crucial for effectiveness and safety, making it a fundamental skill for grapplers and fighters.
