### Achilles Lock #### Skill Level: Intermediate ### Overview: The Achilles Lock, also known as the "Straight Ankle Lock," is a fundamental leg lock technique used primarily in Brazilian Jiu-Jitsu (BJJ) and often seen in submission grappling. This technique targets the Achilles tendon and applies a hyperextension force on the ankle. ### Japanese Name: N/A ### Position: - **Position**: Open Guard, Butterfly Guard, or Standing - **Top/Bottom**: Bottom ### Step-by-Step Instructions: #### **From Open Guard:** 1. **Grip Establishment:** - Start in your opponent’s **open guard** position. - Use your grip to control their **heel** with your dominant hand. 2. **Foot Placement:** - Place your **opposite foot** against their hip for leverage. - Slide your **dominant foot** underneath their opposite thigh. This setup helps to maintain control. 3. **Leg Control:** - Using your arms, guide your opponent’s foot into the crevice of your elbow, latching on to the heel. - Ensure that their Achilles tendon is trapped right above your forearm. 4. **Lock Setup:** - Grip your own **lapel or wrist** with your free hand to enhance the lock (if wearing a gi) or make a gable grip if no gi is used. 5. **Body Positioning:** - Drop your side to the mat where your underhooked leg is. This will help maintain control and positioning. - Press your **hips forward** by arching your back gently. - Simultaneously, **bring your shoulders back** by leaning away from your opponent. 6. **Applying Pressure:** - Ensure your opponent’s toes are **pointing toward their knee** to maximize the lock. - Slowly increase the pressure by pulling the foot into your body like you're trying to hyperextend the legs of their new-dead fish. 7. **Finish:** - Continuously monitor your opponent’s movement and tap if necessary. - Be mindful; press and pull steadily until they tap out. ### Tips: - Maintain tight control over your opponent’s foot to avoid escape. - Avoid cranking aggressively; focus on subtle adjustments and constant pressure application. - Provide your partner the opportunity to tap by exercising control and awareness. The Achilles Lock is effective but relies heavily on technique; avoid muscling through it, as proper leverage application is key to success.
