Defending the Inside Heel Hook from Ushiro Ashi-Garami is among the most critical skills in modern leg lock defense. The reversed entanglement geometry means standard heel hook defenses require significant modification—the angles of attack come from unexpected directions relative to your inverted hip position, and the window between recognizing the attack and suffering knee damage is dangerously short.
The defender in this scenario has already attempted an inversion escape from standard ashi-garami but remains partially trapped. This creates a precarious situation where the attacker’s adjusted grip positioning targets your knee from angles that feel unfamiliar compared to standard heel hook attacks. Your primary defensive objective is preventing heel exposure while systematically working to either neutralize the attack back to a controlled ushiro position or complete your escape into counter-entanglement. The reversed configuration actually offers specific defensive advantages—your inverted hips create rotation pathways that can strip grip if timed correctly, and your free leg has leverage angles for counter-entanglement that do not exist in standard ashi-garami.
Successful defense requires layered responses: immediate heel protection through dorsiflexion and knee rotation, active grip fighting to prevent the attacker from establishing the torso-trapped heel position, and strategic decision-making about whether to continue escaping toward turtle or accept a transitional position like 50-50. Panicked reactions—especially extending the trapped leg or relaxing foot tension—convert survivable positions into immediate submission finishes.
Opponent’s Starting Position: Ushiro Ashi-Garami (Top)
How to Recognize This Attack
- 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
Key Defensive 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
Defensive Options
1. Aggressive hand fighting to strip heel grip before attacker establishes torso trap
- When to use: Immediately upon recognizing the attacker’s hands moving toward your heel area, before they secure the cupping grip and clamp their elbows together
- Targets: Ushiro Ashi-Garami
- If successful: Attacker’s submission attempt is neutralized, returning to standard ushiro ashi-garami position where you can resume your escape sequence
- Risk: If grip stripping fails, you have delayed your positional escape and the attacker may now have a deeper grip than before your intervention
2. Continue rotation toward turtle to complete the escape and clear the entanglement entirely
- When to use: 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
- Targets: Ushiro Ashi-Garami
- If successful: You clear the leg entanglement entirely and arrive in turtle position, eliminating the heel hook threat and resetting the positional exchange
- Risk: If rotation is too slow, the attacker may finish the heel hook during your movement, or follow your rotation to maintain entanglement from a new angle
3. Enter counter-entanglement by attacking the attacker’s free leg with your own outside ashi-garami
- When to use: When the attacker’s leg control has loosened during their grip transition to heel hook setup, exposing their own legs to entanglement
- Targets: 50-50 Guard
- If successful: You establish mutual leg entanglement in 50-50, creating a symmetrical position that neutralizes their finishing advantage and gives you counter-attack options
- Risk: Focusing on counter-entanglement diverts attention from heel protection, and if your counter fails while their heel hook grip is established, you face immediate submission
4. Boot out by forcefully straightening the trapped leg to deny the heel hook angle
- When to use: When the attacker has partial grip but has not yet trapped the heel against their torso, and you have enough leg strength to extend against their control
- Targets: Ushiro Ashi-Garami
- If successful: The straightened leg removes the heel hook angle entirely, forcing the attacker to either re-bend your leg or transition to a different submission like kneebar or ankle lock
- Risk: The straightened leg creates kneebar exposure and you may lose the ability to use knee rotation for defense if the extension fails and they re-capture the bend
Best-Case Outcomes for Defender
→ Ushiro Ashi-Garami
Strip the attacker’s heel grip through aggressive two-on-one hand fighting targeting the cupping hand first, then immediately resume your inversion escape sequence. Alternatively, time your rotation to turtle during the attacker’s grip adjustment phase when their positional control is weakest. Maintain dorsiflexion throughout to deny re-grip opportunities.
→ 50-50 Guard
When the attacker loosens leg control to pursue the heel hook, use your free leg to hook around their near leg and pull yourself into a symmetrical 50-50 entanglement. This neutralizes their finishing leverage by creating mutual vulnerability. From 50-50 you can fight for inside position to eventually reverse or counter-attack.
Test Your Knowledge
Q1: What is the single most important defensive action when you recognize a heel hook attempt from ushiro? A: Maintain maximum dorsiflexion by flexing your foot hard toward your shin and pulling your toes up. This pulls the heel closer to your lower leg, making it extremely difficult for the attacker to establish the cupping grip needed for the finishing rotation. This must be maintained without interruption throughout the entire defensive sequence, even during grip fighting and escape attempts.
Q2: The attacker has trapped your heel against their chest and is beginning to rotate—what is your immediate response? A: At this stage the submission is close to completion and you must act immediately. Use both hands to attack their grip—target the cupping hand that holds your heel first, pulling it away from their chest. Simultaneously rotate your trapped knee inward toward your opposite hip to remove rotational slack. If you cannot break the grip within 1-2 seconds, tap immediately. Do not attempt to outrun a locked-in heel hook through rotation, as this accelerates knee damage.
Q3: How does defending the ushiro heel hook differ from defending a standard inside heel hook? A: The ushiro configuration changes the angle of rotational force—the attacker rotates away from you rather than driving into you, which means your standard defense of turning toward the attacker is less effective. Instead, you must focus on inward knee rotation and grip stripping at your hip line rather than reaching across your body. Your inverted hip position also means escape routes run in different directions, requiring turtle rotation rather than hip escape.
Q4: Your attacker loosens their inside leg control to reach for your heel—what opportunity does this create? A: When the attacker releases inside leg control to pursue the heel grip, they create a window for either completing your escape to turtle through unimpeded rotation, or entering counter-entanglement on their now-exposed legs. Evaluate the depth of their remaining control: if shallow, accelerate your rotation to clear the entanglement entirely. If their outside leg still controls your free leg, use the freed space to enter 50-50 by hooking their near leg.
Q5: When should you accept the tap rather than continue defending the ushiro heel hook? A: Tap immediately when the attacker has established a solid cupping grip with your heel trapped against their torso and has begun rotational movement that you cannot arrest through grip fighting. Tap when you feel any rotational pressure in your knee joint regardless of pain level—heel hook damage occurs before pain signals arrive. Tap when your grip fighting has failed twice consecutively and the attacker re-establishes the heel trap. In training, the threshold should be even lower—tap at the first sensation of controlled rotation rather than testing the limits of your defense.
