The Inside Heel Hook from Ushiro Ashi-Garami represents one of the most technically demanding finishes in modern leg lock systems. This submission targets the knee’s rotational integrity through the reversed leg entanglement configuration, requiring significant adjustments to standard heel hook mechanics due to the opponent’s inverted hip position.
Unlike standard inside ashi-garami heel hooks, the ushiro configuration presents unique challenges. The opponent’s inversion creates different leverage angles, requiring the attacker to modify grip placement and hip positioning to generate effective rotational force. The heel hook grip must be established closer to your own hip line rather than reaching across the opponent’s body, and the finishing rotation follows a different vector than traditional inside heel hook mechanics.
Strategically, this submission capitalizes on opponents who have partially escaped standard leg entanglements through inversion but remain trapped in the reversed configuration. The window for finishing is often narrow—advanced defenders will continue their rotation toward turtle or counter-attack with their own leg entanglement if given time. Understanding the biomechanical differences between ushiro and standard ashi-garami heel hooks is essential for consistent finishing success.

Key Attacking Principles
What are the key principles for executing Inside Heel Hook from Ushiro?
- Adjust grip placement closer to your hip line rather than reaching across opponent’s body due to reversed configuration
- Generate rotational force by rotating your shoulders and torso away from the trapped heel rather than driving forward
- Maintain constant inside leg control on opponent’s thigh to prevent their escape or transition to turtle
- Keep opponent’s heel trapped against your chest or ribs as the fulcrum point for breaking mechanics
- Use your outside leg to control opponent’s free leg and prevent counter-entanglement attempts
- Time the finish during opponent’s adjustment phase when their attention is on escaping rather than defending the heel
Prerequisites
What do you need before attempting Inside Heel Hook from Ushiro?
- Established Ushiro Ashi-Garami position with opponent’s leg trapped in reversed figure-four configuration
- Inside leg controlling opponent’s thigh deeply enough to prevent complete escape or saddle transition
- Outside leg crossing over opponent’s knee line to maintain entanglement integrity
- Opponent’s heel exposed or accessible for grip establishment despite reversed hip orientation
- Upper body positioned to generate rotational force through shoulder and torso movement
Execution Steps
How do you execute Inside Heel Hook from Ushiro step by step?
- Secure leg entanglement: Confirm your inside leg is deeply controlling opponent’s thigh while your outside leg crosses over their knee line. Your hips should be close to their trapped leg with no space for them to extract.
- Control opponent’s free leg: Use your outside leg to actively press their free leg away from your center line. This prevents them from using it as a lever to complete rotation or enter counter-entanglement on your legs.
- Establish heel grip: Reach for their heel with both hands, positioning your grip closer to your own hip line than in standard heel hooks. Cup the heel with your bottom hand while your top hand controls the toes/foot for rotational leverage.
- Trap heel against torso: Pull opponent’s heel tight against your chest or ribs, creating a fixed fulcrum point. Your forearms should clamp around their ankle with elbows squeezed together to prevent heel slippage during rotation.
- Create rotational angle: Angle your torso and shoulders away from the direction you want to rotate the heel. The reversed configuration requires rotating away from opponent rather than driving into them as with standard ashi variations.
- Apply rotational force: Rotate your entire upper body while maintaining the heel trapped against your torso. The rotation should come from your shoulders and hips moving as a unit, not from arm strength alone. The opponent’s knee rotates against its natural range of motion.

Opponent Counters
How might your opponent counter Inside Heel Hook from Ushiro?
- Opponent continues rotation toward turtle to escape entanglement completely (Effectiveness: High) - Your Response: Accelerate the finish before they complete rotation, or follow to back control if they escape the entanglement → Leads to Ushiro Ashi-Garami
- Opponent boots out by straightening their leg to prevent heel exposure (Effectiveness: Medium) - Your Response: Transition to ankle lock or kneebar on the straightened leg, or work to re-bend the knee by driving your hips forward → Leads to Ushiro Ashi-Garami
- Opponent enters counter-entanglement on your legs during your grip establishment (Effectiveness: High) - Your Response: Immediately address their leg control or accept the leg lock exchange if your position is more advanced → Leads to 50-50 Guard
- Opponent hand fights aggressively to strip your heel grip (Effectiveness: Medium) - Your Response: Use your top hand to control their wrist while maintaining heel grip with bottom hand, or transition to saddle for better control → Leads to Ushiro Ashi-Garami
Safety Considerations
What are the safety concerns for Inside Heel Hook from Ushiro?
The Inside Heel Hook from Ushiro is extremely dangerous and can cause severe, career-ending knee injuries including ACL, MCL, and meniscus tears. Damage occurs before pain is felt, making the ‘tap early’ principle critical. Never apply this technique explosively—use slow, controlled pressure and release IMMEDIATELY upon tap. In training, partners should tap at the first sensation of rotational pressure, not when they feel pain. Only practice with experienced training partners who understand leg lock safety protocols. Avoid this technique entirely on training partners with prior knee injuries. In competition, be prepared to release instantly even if the referee hasn’t called the match. The reversed ushiro configuration can make tap signals harder to see—maintain visual or verbal contact with your partner throughout. Consider practicing with catch-and-release drilling before any resistance training.
