Reverse armbar
Also known as Inverted Armbar — the canonical term used on this site.
Training background: Common alternative name — refers to the reversed loading direction
Descriptive — reversed loading direction of the elbow
Reverse armbar is a descriptive name for the inverted armbar — emphasising that the elbow is loaded in the opposite direction from the standard armbar, with the joint hyperextending against a fulcrum on the opposite side of the arm.
Etymology. “Reverse” flags the inverted loading vector relative to the conventional armbar’s geometry. The descriptor appears in coaching vocabulary alongside “inverted armbar” — the two terms refer to the same configuration with slightly different emphasis. “Reverse” tends to be used when the writer wants to flag the directional inversion; “inverted” tends to be used when the writer wants to flag the structural inversion. Both terms are mutually intelligible.
Mechanics. The configuration loads the elbow joint against the same natural-range limit as the standard armbar but from the opposite vector — the hyperextension is achieved by driving the joint backward rather than forward relative to its standard rest position.
Cross-reference. “Inverted armbar” is the canonical site label; “arm crush” (informal) appears in colloquial vocabulary. Full mechanical coverage on Inverted Armbar.
