BJJ Leg Lock System: Complete Guide for No-Gi & Gi | BJJ App Wiki

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 — both offensively and defensively — is no longer optional.

The Leg Lock Hierarchy

Primary Entry Positions

Ashi Garami (Single Leg X Entry)

The foundation of modern leg locks. Both feet on their hip — 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

1. Establish inside ashi garami (both feet on hip).
2. Control their ankle with an "oven mitt" grip (palm facing you, heel in your armpit).
3. Pinch knees, rotate your body — the heel turns, the knee twists.
4. Tap comes quickly — do NOT crank. Rotate slowly and stop immediately at tap.

Straight Ankle Lock

1. Ashi garami entry. Figure-4 on their ankle.
2. Your wrist bone (radius) directly on their Achilles tendon.
3. Arch your back (lean back) — not rotate. Lean = Achilles pressure.

Leg Lock Defense

• Heel hook defense: Keep your heel protected — toes pointing AWAY from their body (never toward). This protects the knee alignment.
• If caught in ankle lock: Bring their heel to your hip — 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 — this breaks the position.

Building Your Leg Lock Game

1. Start with straight ankle locks — learn the mechanics of leg entanglement safely.
2. Add toe holds when your ankle lock entries are solid.
3. Develop ashi garami as your primary entry position — it's the hub of the system.
4. Finally, add heel hooks — only after your entries and safety understanding are solid.
