Armbar from back control
Also known as Back Armbar — the canonical term used on this site.
Training background: The long descriptive form, and the one most likely to be searched
Descriptive — names the position the attack spends to exist
Armbar from back control is the long descriptive name for the back armbar: the trapped arm taken at the moment it peels out of the straitjacket.
Etymology. The name is accurate and slightly misleading at the same time, which is worth knowing. The attack comes FROM back control in the sense that the control isolated the arm, but it does not happen IN back control — finishing it means releasing the seatbelt and the hooks and swinging the legs over. The position is the source and the price, not the setting.
Mechanics. Timing is the technique. The window is the peel itself: an arm still pinned cannot be attacked and an arm returned to the ribs cannot either. The attacker follows the arm out rather than fighting to keep it, which is counter-intuitive enough to need drilling on its own, then comes over the top and confirms the hip is under the elbow before extending — both players are moving, so the lever is frequently offset.
Cross-reference. “Straitjacket armbar” is the more precise label. Full mechanical coverage on Back Armbar.
