### Wrist Lock Wrist locks are versatile submissions that can be employed from various positions, often catching opponents off-guard due to their deceptiveness. They target the small joints, more specifically the wrist, by hyper-flexing or hyper-extending it beyond its normal range of motion. #### Positions: - **Closed Guard** - **Open Guard** - **Side Control** - **Standing** #### Japanese Name - **Kote Gaeshi** or **Gyaku Kote Gaeshi** ### Step-by-step Instructions #### 1. Wrist Lock From Closed Guard 1. **Establish the Guard Position** - Begin in closed guard with your legs securely wrapped around your opponent's waist. - Control your opponent's arms by grabbing the sleeves and bringing them towards your chest. 2. **Create a Frame** - Slide your hand underneath your opponent's arm. - Ensure your forearm is positioned against their arm. - Your other hand should grip your opponent’s wrist, guiding it towards you. 3. **Establish Wrist Control** - With the hand controlling their wrist, use a C-grip to maintain control. - Bend your opponent's wrist forward (flexion) by applying pressure with your thumb on the back of their hand. 4. **Lock the Wrist** - With your supporting forearm, press down to maximize leverage, ensuring their wrist is flexed as much as possible. 5. **Finish the Technique** - Apply steady pressure and keep your opponent's arm pinned against your body. - Let your legs maintain a smooth pressure, ensuring your opponent is unable to posture up. - Wait for the tap once the joint is sufficiently locked. #### Considerations and Safety - **Technique Control**: Wrist locks can be dangerous if applied with excessive force or speed. Always ensure your training partner is comfortable and tap early. - **Wrist Flexibility**: Be mindful of wrist flexibility; some individuals may have more range of motion. - **Position and Leverage**: Proper position of your own body in relation to your opponent’s ensures efficiency and reduces the risk of injury. By mastering wrist locks, practitioners can add a sneaky and technical submission to their Brazilian Jiu-Jitsu arsenal, perfect for occasions when opponents least expect it.
