Straight Ankle Lock Mechanics
The straight ankle lock is the entry-level leg lock available to all belt levels. It targets the Achilles tendon and, while less dangerous than heel hooks, can still cause significant injury if applied aggressively.
Straight Ankle Lock Step by Step
- Control the leg — trap it between your arms and chest
- Place the blade of your wrist (karate chop side) against their Achilles tendon
- Lock your hands in a figure-4 grip
- Lean back and rotate your body outward (away from their body)
- The rotation drives the wrist blade into the tendon

Using Strength Over Technique
Muscling through setups creates bad habits and fails against stronger or more skilled opponents. Focus on leverage and angles.
Skipping Drilling
Techniques only become available in live rolling after extensive drilling. Regular repetition builds the muscle memory needed for execution under pressure.

More Questions
What's the difference between a straight ankle lock and a heel hook?
A straight ankle lock primarily targets the Achilles tendon and ankle joint by applying rotational pressure. A heel hook, on the other hand, targets the knee joint by applying a twisting force to the heel.
How can I avoid getting my ankle locked when someone is attacking my leg?
Prioritize maintaining proper leg structure and avoiding exposed ankles. If someone is attacking your leg, try to 'face' their hips and keep your knee and ankle aligned to prevent them from isolating and attacking your limb.
What are the common mistakes people make when applying an ankle lock?
A common mistake is not isolating the leg properly, allowing the opponent to escape or counter. Another mistake is applying too much pressure too soon, which can lead to injury for both parties and a less effective submission.
