Prone Ankle Lock.

What it is

Ankle lock from prone position hyperextending joint

What you do

Tap immediately when ankle pressure begins - prone position eliminates escape options.

Prone position increases control; tap earlier than supine ankle lock variations.

Never roll defensively toward trapped leg - tightens control and increases damage.

Apply pressure slowly - increased control demands heightened attention to tap signals.

Do not attempt to roll through to supine - maintain position awareness above all.
