Juji-gatame is a popular submission technique used in Brazilian Jiu-Jitsu and judo. It involves isolating an opponent's arm and applying pressure to the elbow joint by using the practitioner's legs. The name "juji-gatame" translates to "crossed arm lock," reflecting the position of the arms during the maneuver. To execute a juji-gatame, the practitioner typically lies on their back and secures one of the opponent's arms between their legs. By crossing their legs and pulling down on the opponent's arm, they create leverage that can force a submission. This technique is effective for controlling an opponent and can be used in both sport and self-defense scenarios.
