SAFETY: Inside Heel Hook from Ushiro Ashi-Garami targets the Ankle, knee ligaments, and surrounding connective tissue. Risk: ACL, MCL, or LCL tear or rupture. Release immediately upon tap.
The inside heel hook from ushiro ashi-garami exploits the reversed leg entanglement created when an opponent inverts to escape standard ashi-garami positions. This variant requires specific grip adjustments and finishing mechanics that differ substantially from standard inside heel hook applications due to the opponent’s inverted hip orientation and the altered geometry of the entanglement. The reversed figure-four configuration changes optimal hand placement on the heel, the direction of rotational force, and the hip positioning needed to generate breaking pressure on the medial knee ligaments.
The ushiro configuration provides a unique attacking angle where the opponent’s heel becomes accessible from a different direction than standard entanglements. The attacker must cup the heel from the reversed angle, reposition their hips to generate proper rotational force toward the opponent’s buttock line, and account for the opponent’s ability to continue rotating as a defensive measure. Timing is critical because the opponent’s inversion often creates a brief window of heel exposure during their transition, and missing this window allows the escape to complete.
Strategically, this submission serves as a high-percentage finishing option that punishes incomplete escape attempts from leg entanglements. Practitioners who develop proficiency with this technique transform defensive inversions from safe escape routes into submission threats, creating a powerful deterrent that fundamentally changes how opponents approach ashi-garami escape sequences at all competition levels. The ability to finish from ushiro closes a critical gap in leg lock systems where opponents could previously invert with relative safety.

Safety Guide
Injury Risks:
| Injury | Severity | Recovery Time |
|---|---|---|
| ACL, MCL, or LCL tear or rupture | CRITICAL | 6-12 months with surgery, potential permanent instability |
| Meniscus tear | High | 3-6 months, may require surgical repair |
| Ankle ligament damage | High | 6-12 weeks for severe sprains |
| Popliteal artery damage (rare but catastrophic) | CRITICAL | Medical emergency requiring immediate surgical intervention |
Application Speed: EXTREMELY SLOW - minimum 5-7 seconds in training, stop at first sign of resistance
Tap Signals:
- Verbal tap (“TAP” or any vocalization)
- Physical hand tap on partner or mat
- Physical foot tap on mat or partner
- Any distress signal including arm waving
- Slapping the mat repeatedly
Release Protocol:
- Immediately stop all rotational pressure the instant partner taps
- Release heel control by opening hands completely
- Release leg entanglement by straightening both legs and moving hips away
- Do not apply any additional pressure during release sequence
- Check with partner verbally before continuing training
Training Restrictions:
- Never apply explosive or sudden rotational force in training
- Never train this submission without instructor supervision initially
- Never use competition speed finishing mechanics in training
- Never practice on partners with existing knee injuries without clearance
- Always maintain communication throughout drilling
- Absolutely forbidden for beginners without extensive positional training first

Playing as Attacker
Key Principles
-
Adjust heel grip placement to account for the reversed hip orientation, cupping the heel from the opposite side compared to standard ashi-garami
-
Maintain inside leg control on the opponent’s thigh throughout the finishing sequence to prevent escape completion
-
Generate rotational force by driving the heel toward the opponent’s buttock line using hip extension rather than arm strength
-
Keep hips heavy and connected to the trapped leg to prevent the opponent from creating extraction space
-
Control the knee line with your outside leg to prevent the opponent from straightening and clearing the entanglement
-
Recognize the transition window between the opponent’s inversion attempt and their escape completion as the optimal attack timing
Execution Steps

Secure ushiro entanglement: As the opponent inverts from standard ashi-garami, follow their rotation by adapting your figure-fou…

Common Mistakes
-
Using standard inside heel hook grip placement without adjusting for the reversed hip orientation
- Consequence: Rotational force is applied at a suboptimal angle, reducing finishing effectiveness and giving the opponent time to establish boot defense or complete their escape
- Correction: Adjust hand placement to cup the heel from the reversed angle. Your primary hand position changes relative to your torso because the opponent’s heel faces a different direction than in standard ashi-garami
-
Lifting hips to reach for the heel grip instead of maintaining heavy pressure on the trapped leg
- Consequence: Creates space that allows the opponent to extract their leg or continue rotating to complete the escape to turtle or standing
- Correction: Keep hips heavy and connected to the opponent’s trapped leg throughout grip establishment. Reach with arms while maintaining downward leg pressure through the figure-four
-
Applying explosive rotational force rather than slow controlled pressure
- Consequence: Causes serious knee ligament injury before the opponent can tap, potentially ending their training career and creating legal liability
- Correction: Always apply rotational pressure over 5-7 seconds minimum in training. Use hip extension rather than arm torque to generate force gradually
Playing as Defender
Key Principles
-
Maintain dorsiflexion (foot flexed toward shin) throughout the entire defensive sequence to hide the heel from the attacker’s grip
-
Prioritize completing the escape rotation to turtle rather than stopping in the reversed entanglement where you are most vulnerable
-
Use both hands to control the attacker’s inside knee to prevent them from deepening entanglement or transitioning to saddle
-
Tap early and without hesitation when you feel rotational pressure on the knee—ligament damage occurs before pain fully registers
-
Control the pace of your escape by moving deliberately rather than explosively to avoid creating heel exposure through uncontrolled movement
-
Monitor the attacker’s hand position to anticipate whether they are attacking the heel hook or transitioning to an alternative submission
Recognition Cues
-
Your inversion escape has been followed and the opponent’s legs have maintained a figure-four configuration around your trapped leg from the reversed angle
-
You feel the opponent’s hands working toward your heel or foot from the reversed direction, indicating they are establishing finishing grips
-
The opponent’s inside leg is controlling your thigh deeply, preventing you from completing your rotation and creating the base for heel hook leverage
-
Your hip mobility is restricted by the opponent’s leg entanglement despite having inverted, and you cannot straighten your trapped leg freely
Escape Paths
-
Complete inversion to turtle by continuing the rotation that initiated the ushiro position, clearing both legs sequentially while maintaining dorsiflexion
-
Grip strip and leg extraction to closed guard by controlling the attacker’s wrists and pulling the trapped leg free while pushing their hips away with the free leg
-
Counter-entanglement to 50-50 guard by entering a mutual leg lock position that neutralizes the attacker’s offensive advantage
