Foundational Concepts | Estima/Tama Lock

Understanding the foundational concepts for the Estima/Tama Lock begins with ensuring the opponent's leg is bent. A straight leg will not allow the technique to work effectively. Create a 'hole' in the belly by sucking in the air, which is where the opponent's foot will be placed, ideally around the belly button area. Strike the toes or the outside of the little toe to initiate the lock.

1. When attacking the leg, use the outside arm to come in, never the inside arm. Using the inside arm makes it easy for the opponent to kick out and escape.
2. Think of the move as a straight ankle lock, using a one, two motion. Locking the grip to the shoulder rather than the shin makes the lock stronger.
3. Thrust the hips to apply pressure and achieve the tap. It's possible to step over for a better angle or fall back to submit.
4. Keep the opponent's leg bent throughout the technique. If the opponent tries to move left or right, follow them to prevent them from straightening their leg and escaping the lock.
5. Control can be maintained by gripping the pants or the shoulder, and hip thrusting to apply the lock. Locking the legs can also add to the control.
6. When the opponent attempts to escape by moving away, turn in the same direction to maintain the lock and prevent the leg from straightening.
7. Visualize creating a hole with the belly, contracting the core to make it feel like the floor to the opponent's foot, simulating a sudden drop as if stepping into a hole.
8. Stay tight and compact to prevent the opponent from freeing themselves. Expanding the body will give them the opportunity to escape.
