### Overview The kimura lock is a dynamic submission technique used in Brazilian Jiu-Jitsu, targeting the opponent's shoulder by hyper-rotating it. This technique employs the wrist and arm in a figure-four grip to gain leverage. While primarily executed from different positions, the closed guard is frequently the setup point. ### Japanese Name N/A ### Position Closed Guard ### Detailed Execution Steps #### Step 1: Establish Closed Guard - **Start by on your back**: Ensure your legs are tightly wrapped around your opponent, securing an effective closed guard. - **Control posture**: Hold onto their neck or sleeve to prevent them from posturing up. #### Step 2: Isolate the Arm - **Cross-grab their wrist**: If your opponent uses their hands to post on the mat, capture and hold one of their wrists with your same-side hand. - **Create an angle**: Scoot your hips out slightly to open an angle for the Kimura. #### Step 3: Secure the Figure-Four Grip - **Release and sit up**: Use your second hand to push yourself up onto your elbow and eventually onto your hand, sitting up slightly alongside your opponent. - **Loop over the arm**: Loop your free arm over your opponent’s trapped arm to secure your grip on your own wrist, forming a figure-four shape. #### Step 4: Breaking Their Posture - **Pull them forward**: Use your legs to pull your opponent towards you while maintaining the figure-four grip. - **Flat on the back**: Fall back to the mat, bringing your opponent’s arm with you in motion, ensuring to keep their wrist close to your chest. #### Step 5: Execute the Submission - **Hold tight**: Ensure the locked grip is tight and secure. Their wrist should be trapped against your chest. - **Finish the lock**: Use the hand gripping their wrist to push their arm, bringing their hand behind the back and maintaining close contact. - **Apply gentle pressure**: Gradually increase pressure for their hand to move upwards while keeping their elbow at a 90-degree angle. ### Tips 1. **Manage their base**: Breaking an opponent's base and control over their posture is crucial to advancing the Kimura. 2. **Maintain hip movement**: Ensure mobility in your hips to establish a proper angle, enhancing power and leverage. 3. **Strengthen grip**: Keep the figure-four grip tight to prevent your opponent’s arm from slipping away. ### Common Mistakes - **Failing to maintain elbow control**: Letting the opponent’s elbow slip results in losing leverage. - **Trying to overpower**: Instead of using brute force, leverage and isolation ensure better application. By following these steps, the kimura lock from closed guard becomes an effective weapon for submission in Brazilian Jiu-Jitsu.
