Harness

Position

The harness (seatbelt grip) is a back control position where the attacker wraps both arms around the defender's torso from behind—one arm over the shoulder and one under the opposite armpit, hands clasped together. It is the primary upper-body control mechanism for back attacks and serves as a launching point for chokes, armlocks, and transitions to crucifix.

Quick Reference

Key principles

  • · The choking-side arm goes over the shoulder while the underhook arm threads under the opposite armpit, creating a diagonal chest clamp.
  • · Keep your chest glued tightly to the defender's back with no space, as even a small gap allows them to turn and escape.
  • · The over-arm (choking side) shoulder should be heavy, driving the defender's posture down and toward the underhook side.
  • · Anticipate the defender stripping the choking-side hand by maintaining a tight clasp and being ready to transition to collar grips, crucifix, or re-pummel.
  • · Use your hooks or body triangle in conjunction with the harness to control the hips and prevent them from sliding down or turning into you.

Execution

  1. 1 From behind the defender, thread one arm over their shoulder across the chest and the other arm under their opposite armpit.
  2. 2 Clasp your hands together tightly (palm-to-palm, Gable grip, or S-grip) at the center of their chest.
  3. 3 Pull your elbows in snug and press your chest flat against their back, eliminating all space.
  4. 4 Establish lower-body control with hooks inside their thighs or a body triangle to anchor your hips to theirs.
  5. 5 Angle slightly toward the choking-side (over-arm side) to set up attacks while keeping constant upper and lower body pressure.

Common mistakes

  • × Clasping hands on the same side of the body instead of diagonally across the chest, which weakens the grip and allows easy peeling.
  • × Leaving hips disconnected from the defender's hips, enabling them to scoot down and escape the back position entirely.
  • × Keeping the head on the underhook side rather than the choking side, exposing your face to shoulder pressure and making choke entries significantly harder.
