Bent-arm armbar escape
Also known as 3/4 Armbar Escape — the canonical term used on this site.
Descriptive — the armbar that wants a bent elbow
Bent-arm armbar escape is the descriptive name for defending the 3/4 armbar, an attack that inverts the usual armbar requirement by working on an elbow the defender has deliberately kept bent.
Etymology. “Bent-arm” marks the inversion. A conventional armbar needs the arm straight, so defenders learn to bend and clasp; the 3/4 variant collects exactly that shape, which is why the name is a warning rather than a description of the finish.
Mechanics. The bent arm that beat the armbar is the entry here, so the defence cannot be more bending. It is connection instead: the elbow is welded to the ribs so the bent limb stays inside the body’s defensive system, hands interlace to re-supplement it, and the defender stacks back into the attacker to collapse the space the ride needs.
Cross-reference. “Three-quarter juji gatame defence” is the Japanese-derived name. Full escape coverage on 3/4 Armbar Escape.
