### Detailed Description of the Closed Guard Armbar The Closed Guard Armbar is a fundamental submission technique taught in Brazilian Jiu-Jitsu (BJJ) that leverages positioning and limb manipulation to apply pressure to an opponent's elbow joint, resulting in a submission. It's an effective move that can be used in both sport BJJ and self-defense scenarios. #### Position - **Initial Position**: Closed Guard - **End Position**: Juji Gatame (armbar lock) #### Japanese Name - **Japanese Name**: Juji Gatame (Cross Arm Lock) #### Instructions 1. **Establish the Closed Guard** - Start with your opponent in your guard. Ensure your legs are wrapped securely around their waist with your ankles crossed to control their posture. - Maintain a firm grip on your opponent to prevent them from posturing up. 2. **Secure Control of the Opponent's Arm** - Choose one of your opponent’s arms to attack. Grip their wrist with a same-side hand (right hand on their right wrist). - Grab the triceps of the chosen arm with your other hand, ensuring you have control to isolate the arm. 3. **Break Opponent's Posture** - Pull your opponent's arm across your body, breaking their posture and making their arm vulnerable. - Use your legs to assist in pulling their body down toward you for better control. 4. **Hip Movement and Angle Change** - Place the foot of the same side of your attacking arm on the opponent's hip. - Pivot your hips to create an angle, facing perpendicular to your opponent by pushing off their hip. 5. **Establish Leg Positioning** - With the non-posted foot (the opposite leg), use the thigh to push into the back of the opponent's head (near their neck) to create downward pressure and keep them off balance. - Swing the leg from the side you pivoted towards over your opponent’s head, establishing a cross-arm lock position. 6. **Execution of the Armbar Submission** - Pinch your knees together tightly around your opponent's arm to maintain control. - Squeeze your legs and arch your hips upward while pulling down on the opponent's wrist to hyperextend the elbow joint. 7. **Finish and Tap** - Ensure pressure on the opponent’s joint by continuing to squeeze your legs together and controlling their wrist. - Hold the position until your opponent taps, indicating the need to release the submission. ### Tips and Considerations - Ensure constant control over your opponent's posture and arm throughout the technique. - Practice hip movement and leg positioning to effectively pivot and create the necessary angle for the submission. - React quickly if your opponent attempts to escape or counter, maintaining your grip and position for a successful submission.
