Why Did This Happen?
The heel hook revolution didn't happen by accident. It was the result of systematic development by a specific team under a specific coach — and it changed the sport forever.
John Danaher: The Architect
John Danaher, a philosophy PhD turned BJJ black belt under Renzo Gracie, began developing a systematic approach to leg locks around 2011-2013. Unlike the scattered leg lock knowledge that existed before, Danaher created a complete system: specific entries, leg entanglement positions (ashi garami, outside ashi, 50/50), and finishing mechanics for inside and outside heel hooks, kneebars, and toe holds.
The system's genius was treating leg locks the same way top-level players treated arm locks and chokes — as a complete positional system with defined entry chains, not isolated techniques.
The Danaher Death Squad: Proof of Concept
Gordon Ryan, Gary Tonon, Nicky Ryan, Craig Jones, and Eddie Cummings proved the system worked at the highest level. At EBI and major ADCC events from 2015-2019, DDS athletes used heel hooks to submit world-class grapplers who had no defense to the position.
ADCC 2019 was the tipping point. Gordon Ryan submitted every opponent — multiple via heel hook. The world watched and recognized: leg locks were no longer optional for serious No-Gi competitors.
Online Instruction: Democratization of the System
The release of Danaher's instructional series on platforms like BJJ Fanatics brought the entire system to anyone willing to study. Thousands of gyms worldwide began drilling ashi garami entries. The technique that once required training with the DDS was now accessible globally.
By 2021, heel hook usage was so widespread that the question shifted from "should I learn heel hooks?" to "how do I defend them?"
Inside vs. Outside Heel Hook: Which Is More Common?
Inside Heel Hook
28%
of all No-Gi submissions (2024)
Set up from ashi garami (single leg X), more accessible entry, still extremely dangerous.
Outside Heel Hook
12%
of all No-Gi submissions (2024)
From outside ashi and 50/50. More dangerous to the knee — stresses ACL and medial structures.
Combined, heel hooks account for 40% of all No-Gi submissions. Inside heel hooks lead because the entry positions (ashi garami, single leg X) are more commonly reached in the flow of a match. Outside heel hooks are less frequent but carry higher injury risk.
How to Defend Heel Hooks
The good news in the data: heel hook defense is improving. Counter-systems are developing as the technique becomes mainstream. Here are the core defensive principles:
1. Tap to position, not to pain
The most critical rule. Heel hook damage happens before pain registers. If the position is locked — tap immediately. Do not wait to feel it.
2. Protect your knee alignment
Keep your toes pointed toward your opponent's hip (not at the ceiling). The "knee line" must stay protected — toes up create vulnerability.
3. Hip escape before fighting the grip
When caught in ashi garami, focus on removing your hip from their control before addressing the heel. Escaping the hip destroys the position.
4. Avoid the 50/50 without knowledge
50/50 is a high-risk entanglement for untrained practitioners. Learn the position before entering it — both offense and defense.
5. Counter-leg lock when trapped
Elite defense includes counter-leg locks. When caught in ashi, you may be able to establish your own ashi on the outside leg — creating a mutual threat.
How to Learn Heel Hooks
Approach heel hook learning systematically. Don't start with the finish — start with the positions.
- Learn ashi garami first. Understand single leg X and outside ashi as positions — how to enter, how to hold, what they threaten.
- Study the knee alignment principles — both how to expose and how to protect. These are two sides of the same understanding.
- Drill the inside heel hook slowly with a consenting partner. Learn the grip (arm-wrap of the heel in the armpit), the body rotation, the finish mechanics.
- Add the outside heel hook from outside ashi garami. Understand why it's more dangerous and train it with extreme care.
- Train positional rounds from leg lock positions — starting in ashi garami, one person attacks, one person defends.
