Leg Locks: The Lower Body Submission System
Leg locks have transformed modern BJJ and no-gi grappling. Understanding the hierarchy — from straight ankle lock to heel hooks — builds a complete lower body attacking game.
Leg Lock Hierarchy by Risk
| Submission | Target | Gi/No-Gi | Risk Level |
|---|---|---|---|
| Straight Ankle Lock | Achilles tendon | Both | Low |
| Kneebar | Knee ligaments | Both | Medium |
| Outside Heel Hook | Lateral knee | No-gi preferred | High |
| Inside Heel Hook | Medial knee + ACL | No-gi | Very High |
Ashi Garami: The Foundation
All leg lock attacks start from leg entanglements. The basic ashi garami (outside ashi) gives ankle lock access. Single leg X (inside ashi) enables heel hooks. 50/50 creates mutual heel hook opportunities.
Straight Ankle Lock Mechanics
- Blade of forearm against Achilles, not calf
- Hip extension to generate power (not arm strength)
- Leg scissors: squeeze to prevent heel hook counters
