### Overview The Kimura is a versatile shoulder lock used to control and potentially submit an opponent by attacking the shoulder joint. Named after Masahiko Kimura, a renowned judoka, this submission is prevalent in both Brazilian Jiu-Jitsu and other grappling arts. In BJJ, the Kimura can be set up from various positions, prominently from the **Side Control, Guard (closed or half), and North South**. ### Positions Used - **Closed Guard** - **Half Guard** - **Side Control** - **North South** ### Step-by-Step Instructions (Closed Guard) 1. **Establish Position:** - Begin by controlling your opponent in the **Closed Guard**. - Keep your legs tightly wrapped around your opponent's waist. 2. **Control the Arm:** - Use your right hand to grab your opponent’s right wrist, pinning it to the mat. - Sit up, using your core, and reach over your opponent’s right arm with your left arm. - Grab your own right wrist with your left hand, securing the figure-four grip. 3. **Break Posture:** - Pull your opponent's elbow down towards their side, securing it close to your midsection. - Use your legs to control their posture, preventing them from sitting up or standing. 4. **Pivot and Finish:** - Rotate your hips to angle your body perpendicular to your opponent. - Your left leg should come up and around their back for added control and leverage. - While holding the figure-four grip, lift your opponent's right elbow upwards while pulling their wrist downward. - Apply gradual pressure to induce the tap, ensuring to go slowly to prevent injury. ### Step-by-Step Instructions (Side Control) 1. **Establish Control:** - Maintain a solid Side Control position with your chest pinning their torso. 2. **Isolate the Arm:** - Use your right arm to control your opponent’s far wrist, pinning it to the ground. 3. **Secure the Grip:** - Bring your left arm over their body, threading it under their tricep. - Lock your hands in the figure-four position, grasping your wrist with your free hand. 4. **Rotate and Finish:** - Step over your opponent’s head with your right leg, trapping it to prevent escape. - Pull their wrist towards their back, ensuring the elbow is at a 90-degree angle. - With controlled pressure, lift their elbow until they tap out. ### Critical Details - **Safety Consideration:** Apply the lock gradually as it can lead to severe shoulder injuries. - **Stay Tight:** Your grips and control of your opponent's posture must be firm and steady. - **Follow Through:** Maintain good technique and control even if your initial attempt doesn’t succeed. Adjust and reapply. Employ the Kimura methodically, ensuring your grips and transitions are seamless to maintain control throughout the sequence.
