Leg Knot

Leg Knot is the wrestling-derived name for the leg entanglement in which both of the opponent’s legs are crossed and controlled in a single configuration — the same position 10th Planet Jiu-Jitsu calls “Z-lock” and submission grappling calls “Game Over.”

Etymology. “Leg Knot” is the catch-wrestling and folkstyle-wrestling description of the configuration: the opponent’s legs are tied against each other in a knotted shape, with neither leg able to post or rotate out of the entanglement because each is trapped by the other. The “knot” naming convention parallels sambo’s sambo knot and emerged independently in catch wrestling and folkstyle, where leg-entanglement vocabulary developed alongside ground-wrestling submission systems. The term entered modern submission grappling through wrestler cross-training and remains in active use in catch-wrestling and folkstyle contexts.

Mechanics. The configuration isolates both of the opponent’s legs by using one as the cross-bar against the other. Neither leg can post, frame, or rotate the knee out of the firing line because each is occupied by the other; the attacker’s inside-space control combines hip pressure with the opponent’s own leg-on-leg pressure to lock the structure.

Cross-reference. Sambo uses Sambo Knot; 10P uses Z-lock; submission-only contexts use Game Over. Full mechanical coverage on Game Over.
