The Outside Heel Hook from Cross Ashi-Garami represents the primary submission threat from one of the most dominant leg entanglement positions in modern grappling. As the attacker, you have the mechanical advantage of the crossed leg configuration controlling your opponent’s hip rotation while isolating their lower leg for the finishing sequence. Your objective is to systematically expose the heel, secure a deep grip behind the Achilles tendon, lock a figure-four configuration, and apply controlled external rotation to attack the lateral knee structures. Success requires integrating leg control maintenance with grip establishment, balancing the urgency of finishing before the opponent escapes with the precision required for safe, effective technique execution. The cross ashi platform gives you multiple finishing options if the heel hook is initially defended, including transitions to toe holds, kneebars, and positional advancement to saddle.

Key Attacking Principles
- Expose the heel before attempting to lock the grip - heel exposure is the prerequisite for all finishing mechanics and must not be skipped
- Thread the attacking hand deep behind the Achilles tendon with the wrist blade directly behind the heel bone for maximum rotational force transmission
- Lock the figure-four grip with elbows tight to the chest before initiating any rotation to prevent grip stripping under pressure
- Generate rotation through core and hip movement rather than arm strength alone - the torso creates power while the arms transmit it to the heel
- Maintain inside hook depth throughout the finishing sequence to control opponent’s hip rotation and prevent defensive turning
- Apply progressive, controlled pressure rather than explosive cranking to allow training partners time to recognize the submission and tap safely
Prerequisites
- Established cross ashi-garami position with inside hook deep behind opponent’s hip and outside leg crossed over their shin
- Opponent’s trapped leg extended or semi-extended with the heel accessible for grip establishment
- Both hands free from positional maintenance duties and available for heel grip configuration
- Perpendicular hip angle to opponent’s body established for optimal control and finishing leverage
- Opponent’s defensive hand fighting neutralized or manageable through superior positional pressure
Execution Steps
- Verify Cross Ashi Control: Confirm your inside hook is deep behind the opponent’s hip and your outside leg crosses firmly over their shin at mid-calf level. Squeeze your knees together to maintain constant tension on the trapped leg, preventing any slack that would allow defensive movement or leg retraction. Your hips should be perpendicular to the opponent’s body.
- Expose the Heel: Use your outside hand to control the opponent’s foot by gripping the toes or ball of the foot. Push the foot down and away from their body to extend the ankle and expose the heel, clearing any defensive grip they maintain on their own foot or ankle. This heel exposure step is the prerequisite for all finishing mechanics.
- Thread the Attacking Hand: Slide your inside hand behind the opponent’s Achilles tendon with your palm facing their calf muscle. Thread deeply so that the blade of your wrist sits directly behind the calcaneus (heel bone), creating the primary connection point for rotational force transmission. Your fingers should point toward their toes for optimal grip alignment.
- Lock the Figure-Four Grip: Bring your outside hand over the top of your inside wrist and clasp your own bicep or forearm to create a Kimura-style figure-four grip configuration. This interlocking grip generates maximum rotational force while preventing the opponent from stripping individual hand grips through hand fighting. Pull your elbows tight against your chest immediately.
- Secure Hip Control: Angle your body perpendicular to the opponent’s hip line and drive your hips forward into their trapped leg to prevent them from rotating their hips to relieve pressure. Your inside hook must stay deep to block their hip from turning toward you, which would allow them to hide the heel or reduce the rotational torque reaching the knee joint.
- Apply External Rotation: Rotate the heel outward, away from the opponent’s midline, by turning your entire torso as a unit while maintaining the tight grip configuration. The rotation should come from your core and hip drive rather than arm strength alone. Apply pressure gradually and progressively, giving your training partner time to recognize the submission and tap safely.
- Bridge and Finish: Drive your hips forward into the opponent’s leg while continuing the rotational pressure to maximize torque on the knee joint. The combination of forward hip pressure and external heel rotation creates a twisting force attacking the lateral knee ligaments. Maintain full control throughout and release immediately upon any tap signal, verbal or physical.

Opponent Counters
- Opponent hides the heel by sharply flexing their knee and rotating the knee inward toward the attacker (Effectiveness: High) - Your Response: Use foot manipulation to re-expose the heel by gripping toes and extending the ankle, or transition to toe hold or kneebar which capitalize on the bent-knee defensive posture → Leads to Cross Ashi-Garami
- Aggressive hand fighting to strip the heel grip before the figure-four configuration locks (Effectiveness: High) - Your Response: Tighten the grip and increase forward hip pressure and leg squeeze to overload the opponent’s defensive capacity, or release and immediately re-grip from a different angle → Leads to Cross Ashi-Garami
- Counter-rotation by rolling toward the heel hook direction to relieve rotational pressure on the knee (Effectiveness: Medium) - Your Response: Follow the rotation with your entire body and maintain grip throughout, increase forward hip drive to prevent the opponent from completing the counter-rotation sequence → Leads to Cross Ashi-Garami
- Boot scoot escape using the free leg to push off the attacker’s body and create distance from the entanglement (Effectiveness: Medium) - Your Response: Drive hips forward to close any distance created and tighten the inside hook to prevent separation between bodies → Leads to Cross Ashi-Garami
- Counter-entanglement by threading the free leg inside to establish their own leg attack position (Effectiveness: Medium) - Your Response: Maintain cross position integrity by squeezing the outside leg cross tighter and prioritize finishing the heel hook before the counter-entanglement is complete → Leads to 50-50 Guard
Test Your Knowledge
Q1: What is the correct grip configuration for finishing the outside heel hook from cross ashi? A: The primary grip is a figure-four configuration with the attacking hand threaded behind the Achilles tendon, palm facing the calf, and the supporting hand clasping the wrist to grip the bicep. Elbows must be pulled tight to the chest to maximize rotational leverage and prevent grip stripping. The blade of the wrist should sit directly behind the calcaneus for optimal force transmission through the heel to the knee.
Q2: Your opponent begins tucking their heel by bending their knee sharply toward their body - how do you adjust? A: When the opponent flexes their knee to hide the heel, you have two primary options. First, use foot manipulation by gripping their toes with your outside hand and pushing the foot down to re-extend the ankle and re-expose the heel. Second, if the knee flexion is strong and persistent, transition to a toe hold attack which capitalizes on the bent knee position, or switch to a kneebar by repositioning your hips over their knee joint.
Q3: What direction of rotational force defines the outside heel hook and why is this mechanically significant? A: The outside heel hook applies external rotation, rotating the heel outward away from the opponent’s midline. This direction attacks the lateral collateral ligament and the posterolateral corner of the knee. It is mechanically significant because the knee has limited natural range of motion in external rotation compared to internal rotation, meaning less movement is needed before the submission becomes effective and potentially injurious to the joint structures.
Q4: Your opponent grabs your wrist with both hands to strip your heel grip - what is your response? A: Tighten your figure-four grip and pull your elbows closer to your chest to make the grip harder to break. Simultaneously drive your hips forward and increase leg pressure with your cross to overload their defensive capacity across multiple axes. If they persist in the grip fight, you can release and immediately re-grip from the opposite angle, or transition to a straight ankle lock where their upright grip-fighting posture leaves the ankle exposed.
Q5: What is the most critical body position element during the finishing sequence of the outside heel hook? A: Hip positioning perpendicular to the opponent’s body with forward hip drive into the trapped leg is the most critical element. Your hips provide the structural foundation for the entire submission by controlling the opponent’s hip rotation, preventing defensive movement, and generating the forward pressure that combines with heel rotation to create finishing torque. Without proper hip position, arm strength alone cannot generate sufficient force to finish against a resisting opponent.
Q6: When should you abandon the outside heel hook attempt and transition to an alternative attack? A: Transition when the opponent successfully hides their heel behind strong knee flexion that you cannot overcome with re-exposure techniques, when your grip has been fully stripped and re-gripping would cost too much positional control, or when the opponent has begun a successful counter-rotation threatening to reverse the entanglement. Flow to toe holds, kneebars, or transition to saddle position to maintain offensive pressure from a fresh angle rather than forcing a failing attack.
Q7: What role does the inside hook play during the heel hook finishing sequence? A: The inside hook serves as the primary hip control mechanism during the finish. It prevents the opponent from turning their hips toward you, which would hide the heel, and from bridging away, which would create escape space. The inside hook must stay deep behind the opponent’s hip throughout the entire finishing sequence. Losing inside hook depth during the finish allows defensive hip movement that significantly reduces the rotational torque reaching the knee joint.
Safety Considerations
The outside heel hook is among the most dangerous submissions in all of grappling. It attacks the lateral knee ligaments (LCL, posterolateral corner) and can damage the MCL and ACL through rotational force applied via the heel. Unlike most joint locks, heel hooks produce minimal pain before structural damage occurs, meaning the knee can be seriously injured before the defender feels significant discomfort. Always apply rotation slowly and progressively in training. Release the submission immediately upon any tap, verbal or physical. Communicate clearly with training partners about leg lock rules before rolling. Never apply explosive rotation. If your partner does not tap and you feel structural resistance changing, stop and communicate. Training partners should tap early when caught in heel hooks rather than attempting to escape locked positions. Injuries from heel hooks can require reconstructive surgery and six or more months of rehabilitation.
