BJJ Leg Lock System: Complete Guide for No-Gi & Gi
β°Contents
Master the BJJ leg lock system: heel hooks, ankle locks, kneebars, entries, leg lock defense, and how to build a complete leg attack game.
The Leg Lock Revolution
Leg locks were once considered a specialty technique. Today, they are a complete attacking system that has changed the sport at every level. In no-gi competition, leg lock proficiency is arguably the most important single skill set you can develop. Understanding leg locks β both offensively and defensively β is no longer optional.
The Leg Lock Hierarchy
| Technique | Target | Danger Level | Ruleset |
|---|---|---|---|
| Straight Ankle Lock | Achilles tendon | β Low | All levels, all rulesets |
| Kneebar | Knee ligaments | ββ Medium | Purple+ (IBJJF gi) |
| Toe Hold | Foot/ankle ligaments | ββ Medium | Blue+ (IBJJF gi) |
| Outside Heel Hook | Lateral knee ligaments | βββ High | No-gi competitions, Brown+ IBJJF gi |
| Inside Heel Hook | Medial knee ligaments (ACL) | ββββ Very High | No-gi, Black belt IBJJF gi |
Primary Entry Positions
Ashi Garami (Single Leg X Entry)
The foundation of modern leg locks. Both feet on their hip β one foot on their hip, one behind their knee (or between their legs for inside ashi).
Outside Ashi (Honey Hole / Saddle)
For outside heel hooks and kneebars. Your outside leg is between their legs; inside leg blocks their hip.
50/50 Guard
Both fighters have mutual inside ashi garami. Creates the heel hook exchange that defines modern no-gi grappling.
Finishing Heel Hooks
Inside Heel Hook
- Establish inside ashi garami (both feet on hip).
- Control their ankle with an "oven mitt" grip (palm facing you, heel in your armpit).
- Pinch knees, rotate your body β the heel turns, the knee twists.
- Tap comes quickly β do NOT crank. Rotate slowly and stop immediately at tap.
Straight Ankle Lock
- Ashi garami entry. Figure-4 on their ankle.
- Your wrist bone (radius) directly on their Achilles tendon.
- Arch your back (lean back) β not rotate. Lean = Achilles pressure.
Leg Lock Defense
- Heel hook defense: Keep your heel protected β toes pointing AWAY from their body (never toward). This protects the knee alignment.
- If caught in ankle lock: Bring their heel to your hip β this neutralizes the angle. Then roll toward the outside.
- "Don't knee-bar yourself": When escaping ashi garami, never straighten your knee into a kneebar position while stepping over.
- The "step over" escape: From outside ashi, step your free leg over their top leg β this breaks the position.
Building Your Leg Lock Game
- Start with straight ankle locks β learn the mechanics of leg entanglement safely.
- Add toe holds when your ankle lock entries are solid.
- Develop ashi garami as your primary entry position β it's the hub of the system.
- Finally, add heel hooks β only after your entries and safety understanding are solid.
