The problem
You are behind them. Every submission in the position is available to you and none is available to them. Almost all of the difficulty is in keeping it, because the defender has a well-known escape route and enough time to use it.
Objective
Maintain chest-to-back connection and control of the near shoulder line while the defender attempts to turn in or slide out, and finish before the position degrades.
Core concept
Back control is a chest connection with legs attached, not a leg position with a chest behind it. Hooks that hold while the chest is detached are hooks that get stripped.
The defender’s escape is nearly always the same shape: get their shoulders to the mat on one side, then turn in. Everything the attacker does is either preventing that rotation or punishing it.
Key mechanics
- Seat belt. One arm over the shoulder, one under the armpit, hands connected. This governs which way they can turn.
- Chest to their upper back. Connection is the position. Space here is the beginning of the escape.
- Stay on the seat-belt side. As they turn, travel with them rather than resisting from square.
- Hooks or a body triangle, chosen deliberately. Hooks are mobile and strippable; the body triangle is more secure and less mobile, and it exposes an ankle. Neither is universally correct.
- Head position. Your head on the same side as the underhook denies them the frame they need to turn.
Common errors
- Crossing the ankles. Long-standing basic error, easily attacked with a footlock.
- Holding with the legs while the chest floats.
- Squaring up as they turn instead of following.
- Chasing a choke and losing the seat belt to get it.
- Sitting in a body triangle with no plan, which converts a dominant position into a stall.
Safety
Rear strangles restrict blood flow and act fast. Never hold one past a tap, never apply one on someone who cannot signal, and treat any loss of consciousness as a medical event requiring immediate attention and a stop to training. Body triangles place real load on the ankle of the crossing leg.

Training progression
- Maintenance only. Attacker may not attack; defender escapes. Reset each time the position is lost. This is the drill that builds the position.
- Add the seat-belt-side rule: attacker must stay on the correct side while the defender turns repeatedly.
- Attacker chooses hooks or body triangle before the round and must keep the choice, to learn what each costs.
- Add finishes only once maintenance is reliable.
