SAFETY: Outside Heel Hook from Saddle targets the Knee joint, ankle joint, and surrounding ligaments. Risk: ACL tear (anterior cruciate ligament rupture). Release immediately upon tap.
The outside heel hook from the Saddle represents a devastating secondary submission option within the modern leg lock hierarchy. While the inside heel hook remains the primary and highest-percentage attack from this position, the outside heel hook serves as a critical complement that transforms the Saddle into a complete submission dilemma. When an opponent successfully defends the inside heel hook by rotating their knee inward and hiding their heel toward their centerline, they inadvertently expose the lateral side of their knee to outside rotational forces. This creates a binary threat where every defensive adjustment against one attack opens vulnerability to the other.
Executing the outside heel hook from the Saddle requires a distinct grip reconfiguration compared to the inside variant. Rather than cupping the heel and applying medial rotation, the attacker must transition their grip to generate lateral rotational torque on the opponent’s knee joint. This typically involves adjusting the figure-four angle so that the rotating force drives the heel outward, targeting the lateral collateral ligament, lateral meniscus, and potentially the anterior cruciate ligament from a different mechanical vector. The perpendicular alignment inherent to the Saddle position provides the structural base necessary to execute this grip transition while maintaining positional control throughout the switch.
The combination of inside and outside heel hook threats from the Saddle creates one of the most difficult submission dilemmas in modern no-gi grappling. This dual-threat capability, reinforced by the Saddle’s inherent positional dominance through hip pressure and inside leg position, makes the outside heel hook a technique that every serious leg lock practitioner must develop. However, the extreme danger of this submission to the knee joint demands rigorous safety protocols—practitioners must apply rotational force with extreme control and immediately release upon any tap signal, as knee ligament damage from heel hooks can be career-ending and often occurs before the defender feels significant pain.

Safety Guide
Injury Risks:
| Injury | Severity | Recovery Time |
|---|---|---|
| ACL tear (anterior cruciate ligament rupture) | CRITICAL | 9-12 months with surgical reconstruction |
| MCL tear (medial collateral ligament damage) | CRITICAL | 6-12 months depending on grade |
| Meniscus tear | High | 3-6 months with potential surgery |
| LCL damage (lateral collateral ligament) | High | 6-8 weeks to 6 months |
| PCL strain (posterior cruciate ligament) | High | 3-6 months |
| Ankle ligament damage | Medium | 4-8 weeks |
Application Speed: EXTREMELY SLOW - minimum 5-7 seconds progressive pressure in training, NEVER sudden rotation
Tap Signals:
- Verbal tap (primary)
- Physical hand tap on partner or mat
- Physical foot tap with free leg
- Any vocal distress signal
- Frantic movement or panic response
- Any indication of discomfort
Release Protocol:
- Immediately release rotational pressure on heel
- Release the figure-four grip or heel cup
- Remove hip pressure and extension
- Allow opponent to straighten leg naturally
- Check partner’s condition before continuing
- Never apply rotation while releasing
Training Restrictions:
- NEVER apply sudden rotational force - always slow and progressive
- NEVER practice at competition speed during training
- NEVER continue past first sign of discomfort
- Only train with experienced partners who understand leg locks
- Always ensure clear communication before training leg locks
- Tap early and often - do not test flexibility limits
- Prohibited for white and blue belts in most IBJJF competitions
- Never practice on injured knees or with prior knee injuries without medical clearance

Playing as Attacker
Key Principles
-
Read the defender’s knee rotation to determine whether inside or outside heel hook is available before committing to a grip
-
Maintain perpendicular hip pressure throughout the grip transition to prevent escape opportunities during the switch
-
Generate lateral rotation through coordinated hip extension and forearm torque rather than isolated wrist twisting
-
Control the opponent’s free leg with your top leg to prevent them from creating counter-rotation during the finish
-
Establish the heel cup grip before connecting the figure-four to avoid telegraphing your rotational direction
-
Apply rotational force progressively and slowly in training, allowing your partner time to tap before ligament damage occurs

Common Mistakes
-
Attempting the outside heel hook without first confirming the opponent has closed the inside path
- Consequence: The inside heel hook is higher percentage from saddle; attacking outside when inside is available wastes a superior attacking opportunity
- Correction: Always probe the inside heel hook first. Only transition to outside when the opponent’s defensive knee rotation has genuinely blocked the inside path and exposed the lateral heel.
-
Releasing hip pressure during the grip transition from positional control to finishing grip
- Consequence: Creates space that allows the opponent to begin escape sequences, potentially losing the entire saddle position during the grip change window
- Correction: Maintain hip drive throughout the grip transition. Keep your hips pressured forward into their thigh even while your hands are changing position. The grip change should not affect your lower body control.
-
Applying rotation through isolated wrist movement rather than coordinated upper body torque
- Consequence: Insufficient rotational force to finish against a resistant opponent, and increased risk of wrist injury to the attacker from straining small joints against larger structures
- Correction: Generate rotation by turning your entire torso and shoulders while keeping the figure-four locked. The rotation should come from your core and back muscles, not your wrists and forearms.
Playing as Defender
Key Principles
-
Protect the heel above all else—any rotational exposure dramatically increases submission probability and injury risk
-
Recognize the attacker’s grip transition from inside to outside heel hook as early as possible to deploy the correct defensive response
-
Never explosively pull the trapped leg away from the attacker—this creates kinetic energy that magnifies joint damage if the heel is controlled
-
Move your body toward the attacker to reduce extension rather than trying to retract the leg away from their grip
-
Address the attacker’s grips systematically before attempting large positional escapes
-
Tap immediately when rotational force begins loading the knee—ligament damage from heel hooks occurs before significant pain is felt
Recognition Cues
-
Attacker shifts their bottom hand from positional control to cup your heel from the lateral side, with fingers wrapping toward the outside of your foot
-
Attacker’s forearm angles change to set up lateral rotation rather than the medial rotation used for inside heel hooks
-
You feel the attacker threading their arm under your Achilles tendon from a different angle than the standard inside heel hook figure-four
-
Increased hip extension pressure combined with the attacker’s torso beginning to rotate, indicating imminent lateral rotational force on your heel
Escape Paths
-
Strip attacker’s heel cup grip, clear their hip pressure with free leg frame, then extract trapped leg through systematic hip escape to recover closed guard or half guard
-
Counter-rotate your body to relieve rotational stress, fight grips to free the heel, then use free leg to push attacker’s hips and create space for leg extraction to open guard
-
Tap immediately and reset when the outside heel hook mechanics are fully engaged and rotational force is loading the knee beyond your ability to defend
