### Kimura Lock The Kimura Lock is a widely used submission technique in Brazilian Jiu-Jitsu (BJJ) that targets the opponent's shoulder. Named after Masahiko Kimura, this effective technique can be applied from multiple positions. Here, we will focus on executing it from the **Guard**. ### Japanese Name N/A ### Position - **Closed Guard** - **Open Guard** ### Top or Bottom - **Bottom** ### Detailed Instructions #### Starting From Closed Guard: 1. **Control the Wrist** - Begin with your opponent inside your closed guard. - Use your left hand to grip your opponent's right wrist, pulling it across your chest. 2. **Create an Isolation** - Open your guard and shift your hips slightly to your right side. This should create an angle. 3. **Overhook & Underhook** - Simultaneously, use your right hand to reach over your opponent's right arm. - Dive it under and back over your opponent's right wrist, creating a figure-four grip and securing the arm with both of your hands. - Hold onto your own left wrist with your right hand. 4. **Break the Posture** - Pull your opponent's posture down by bringing their captured arm and shoulder close to the mat. 5. **Finish the Lock** - Keep your opponent's hand in check while elevating their elbow. - Maintain pressure on your grip and slowly lever their hand towards the back of their head. - Apply gentle, controlled pressure until your opponent taps, signaling submission. ### Variations and Key Points: - **Angle Adjustment:** Make sure your hips are at an angle to effectively break your opponent’s posture and apply the lock efficiently. - **Grips**: Ensure a figure-four lock by maintaining a firm grip on your own wrist. Proper grips enhance control and pressure. - **Safety:** Always prioritize control and apply pressure gently to avoid causing injury. ---
