## Straight Arm Lock from Mount ### Overview: The Straight Arm Lock, commonly referred to as an "Armbar" in Brazilian Jiu-Jitsu, is a fundamental submission technique that can be executed from various positions. It targets the opponent's elbow joint, using leverage to straighten and hyperextend the arm. ### Japanese Name: Juji Gatame ### Position: Mount ### Steps to Perform the Straight Arm Lock: 1. **Establish Mount Position:** - Maintain strong stability and base while mounted over your opponent. Ensure your knees are tightly against their sides, and toes are hooked under their hips to hold position effectively. 2. **Isolate the Target Arm:** - Use your right hand to grasp your opponent's right wrist. Your thumb should face downward, creating a C-clamp grip. - With your left hand, thread underneath their right elbow, gripping your own right wrist to form a figure-four grip. 3. **Pin and Rotate:** - Keeping the wrist pinned against the mat, drive your weight forward and off the opponent slightly, allowing you to rotate their arm and open space for maneuvering. 4. **Shift Leg and Base:** - Swing your left leg over to the other side of your opponent's face. Your left calf should press against the back of their neck as your foot hooks tightly under their opposite armpit. - Your right knee must pinch tightly against their shoulder for control. 5. **Creating Leverage:** - Use your hips to elevate slightly, creating enough space to pass your left leg around the opponent's trapped arm. - Then scoot your hips underneath the opponent's shoulder while keeping their thumb facing upwards. 6. **Achieving the Lock:** - Sitting back slightly, bring their elbow snugly against your inner thigh. - Pinch your knees tightly together and keep your feet in close proximity to either their body or ground. 7. **Finish the Submission:** - With the arm now fully extended between your thighs, push your hips forward while pulling their wrist downwards. - Ensure continued control over their thumb, maintaining a supine position to avoid any potential escape. 8. **Apply Pressure with Caution:** - Apply pressure slowly and progressively to avoid injury, and be prepared to release when your training partner taps. ### Tips: - Concentrate on maintaining control up to the point of application rather than rushing the lock blindly. - Transition smoothly and use hip movement dynamically to keep pressure on the opponent's joints throughout the execution.
