Understanding Heel Hooks
Heel hooks are among the most effective and most dangerous submissions in BJJ. Unlike knee bars or toe holds, they attack the knee ligaments in ways that can cause injury before significant pain — making tap timing critical.
Inside vs Outside Heel Hook
| Type | Position | Joint Attacked | Legality |
|---|---|---|---|
| Inside Heel Hook | You are inside their legs | Medial knee (MCL, meniscus) | Legal: brown/black (IBJJF) |
| Outside Heel Hook | You are outside their legs | Lateral knee, ACL | Legal: brown/black (IBJJF) |
Heel Hook Finishing Mechanics
- Control the leg with body lock (legs locked around their thigh)
- Cup the heel with your inside arm, elbow pointing up
- Lock your hands together (seatbelt grip)
- Rotate internally (toward your own body) using your entire body
- The rotation attacks the ligaments — do NOT crank, rotate slowly
⚠️ Safety First: Heel hooks have injured world-class athletes who misjudged the finishing pace. Always use controlled rotation in training and stop immediately at the tap.
💡 Pro Tip: Learn to defend heel hooks before learning to attack. Understanding how to remove the leg, break the grip and escape is more important than the submission itself.
Frequently Asked Questions
What is the difference between inside and outside heel hook?
Inside heel hook: you are on the inside of your opponent's leg with the heel pointed toward you, attacking the medial knee structures. Outside heel hook: you are on the outside of the leg, attacking the lateral knee and ACL.
Why are heel hooks considered dangerous?
Heel hooks attack the knee ligaments (ACL, MCL, LCL) and can cause injury before significant pain — unlike many other submissions. This is why they are restricted in beginner and intermediate competition divisions.
How do I apply a heel hook safely in training?
Use slow, controlled rotation. Never crank. Look for your partner to tap and stop immediately. Practice the position and entry without applying finishing pressure until you have proper mat awareness.
