//01—About this position

What it is

Leg entanglement where both your legs thread through the opponent's leg structure from behind. Both of your legs control their near leg with your inside leg hooking behind their knee and your outside leg triangled over. This creates dual control for heel hooks, knee bars, and toe holds.

The step-by-step execution guide lives in the app — 6-step breakdown, biomechanics, and situational tips.
