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.

Playing as Attacker
Key Principles
-
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
Execution Steps
-
Secure leg entanglement: Confirm your inside leg is deeply controlling opponent’s thigh while your outside leg crosses over t…
-
Control opponent’s free leg: Use your outside leg to actively press their free leg away from your center line. This prevents them…
-
Establish heel grip: Reach for their heel with both hands, positioning your grip closer to your own hip line than in stan…

Trap heel against torso: Pull opponent’s heel tight against your chest or ribs, creating a fixed fulcrum point. Your forearms…

Create rotational angle: Angle your torso and shoulders away from the direction you want to rotate the heel. The reversed con…

Apply rotational force: Rotate your entire upper body while maintaining the heel trapped against your torso. The rotation sh…
Common Mistakes
-
Using standard heel hook grip positioning instead of adjusting for reversed configuration
- Consequence: Grip is weak and easily stripped because leverage angles are incorrect for the ushiro position
- Correction: Position grip closer to your hip line with elbows tight, adapting to the opponent’s inverted hip orientation
-
Attempting to finish by driving forward into opponent as with standard inside ashi
- Consequence: Rotational force is dissipated and opponent can easily escape or straighten their leg
- Correction: Rotate away from opponent by turning your shoulders and torso, using the heel trapped against your chest as the fulcrum
-
Releasing inside leg control to focus exclusively on the heel hook finish
- Consequence: Opponent escapes to turtle or standing while you have grip but no positional control
- Correction: Maintain inside leg control on their thigh throughout the entire finishing sequence
Playing as Defender
Key Principles
-
Maintain dorsiflexion (foot flexed toward shin) throughout the entire defensive sequence to deny heel exposure and prevent the attacker from establishing a cupping grip on your heel
-
Rotate your trapped knee inward toward your opposite hip to take slack out of the heel hook mechanism and reduce rotational leverage available to the attacker
-
Prioritize grip fighting on the attacker’s hands before they establish the heel-to-chest trap, since breaking established grips is exponentially harder than preventing them
-
Use your free leg as an active defensive weapon by creating counter-entanglement threats or pushing the attacker’s hips to create separation and reduce finishing leverage
-
Make early decisions about escape direction—continuing rotation to turtle versus entering 50-50—rather than stalling in the reversed position where submission risk escalates with every second
Recognition Cues
-
Attacker’s hands shift from controlling your leg entanglement to reaching for your heel or ankle area, indicating transition from position maintenance to submission attack
-
Attacker’s upper body begins rotating away from you while pulling your foot toward their chest, establishing the torso-trapped fulcrum needed for the reversed finishing mechanics
-
Attacker’s outside leg increases pressure on your free leg while their inside leg maintains deep thigh control, indicating they are securing position for the finishing sequence
-
You feel your heel being pulled toward the attacker’s rib cage or chest with increasing tension, and their elbows begin squeezing together around your ankle joint
-
Attacker’s hip pressure shifts from controlling your thigh to angling their torso for rotation, creating a distinct change in the direction of force you feel through the entanglement
Defensive Options
-
Aggressive hand fighting to strip heel grip before attacker establishes torso trap - When: Immediately upon recognizing the attacker’s hands moving toward your heel area, before they secure the cupping grip and clamp their elbows together
-
Continue rotation toward turtle to complete the escape and clear the entanglement entirely - When: When the attacker commits to the heel hook attempt and loosens their leg control to prioritize the finish, creating space for you to complete your inversion
-
Enter counter-entanglement by attacking the attacker’s free leg with your own outside ashi-garami - When: When the attacker’s leg control has loosened during their grip transition to heel hook setup, exposing their own legs to entanglement
Position Integration
The Inside Heel Hook from Ushiro occupies a critical position in modern leg lock systems as the primary finishing option when opponents attempt to escape standard ashi-garami positions through inversion. It integrates with the broader leg entanglement system by providing a submission threat that punishes incomplete escape attempts. When combined with transitions to saddle, back control, and ankle locks, the ushiro heel hook creates a decision tree where opponents must choose between submission risk and positional disadvantage. The technique connects directly to saddle and honey hole systems when the finish isn’t available, and to back control when opponents continue their rotation past ushiro. Understanding this technique is essential for both attacking from ushiro and defending against it when you find yourself trapped in the reversed configuration.
