Violin armbar escape
Also known as Inverted Armbar Escape — the canonical term used on this site.
Colloquial — the arm cradled like a violin at the shoulder
Violin armbar escape is the colloquial name for defending the inverted armbar, so called because the attacker cradles the arm high against their own shoulder in the shape of a violinist holding the instrument.
Etymology. The image is descriptive rather than technical, which is why the term stays informal. It captures the one thing that matters mechanically — the arm is held supinated and high, not extended across a hip — and that is the opposite orientation to a standard armbar.
Mechanics. Because the lock loads in supination, pronation defeats it: turning the thumb down moves the joint line off the fulcrum and the press has nothing to hyperextend against. Earlier, the elbow stays bent and tight to the body so the arm never reaches the loading angle at all.
Cross-reference. “Reverse armbar defence” is the alternate name. Full escape coverage on Inverted Armbar Escape.
