An arm grab is a type of martial grapple on the ground and designed to make the opponent surrender (knocking on the ground with the hand or, in combat, breaking the arm). It is usually taught in judo and ju jitsu as it is the most common "hand to hand" combat martial arts, however it can be applied to any martial art where ground combat is required. It can be a very effective move if done right. The steps below will help you get a general understanding of the concept and the method to follow to apply it.
Steps
Step 1. Grab the opponent's forearm with both hands so that the wrist is facing up; the opponent must be with his back to the ground ("belly up") for this type of hold
Step 2. Position your legs so that your knees are bent and your opponent's arm and elbow are between your legs
Step 3. Push both feet up, pulling your opponent's arm towards you to bring your body as close as possible to his, always keeping his arm with the wrist up
As a result you should have the crotch under or very close to his shoulder.
Step 4. Drop both legs onto the opponent's chest (one to the left and one to the right of the immobilized arm) while keeping his elbow straight in tension while continuing to pull the wrist towards you
Step 5. Using your opponent's chest as a pivot, pull their wrist towards your chest while pressing upward with your hips
Very light pressure is enough to make the grip effective.
Advice
- Put all your weight on the opponent.
- Use your hands to hold the opponent's forearm or wrist in place, rather than "squeezing" the limb to your chest by bending your arms.
- Grip the arm SLOWLY. Train with friends. If the opponent is not a very flexible person, this technique risks really hurting him and causing serious damage. Increase your pressure by 10% each time. 10, 20, 30% until the opponent 'hits' the ground. If you suddenly go from 0 to 70% and your opponent's threshold is at 30%, try to imagine what can happen …
- Try to keep the opponent's wrist in the same direction as his chest, both facing up.
Warnings
- Until you have full control of the technique, don't experiment with inexperienced people; the technique can be used to break an elbow or sprain a shoulder and requires very little force to hurt and cause injury.
- When the opponent shows surrender (usually by "hitting the ground") he relaxes the hips and loosens his grip.
