Twisting arm control
Also known as Mir Lock — the canonical term used on this site.
Training background: Descriptive informal term
Descriptive — rotational arm control variant
Twisting arm control is a descriptive informal label sometimes applied to the Mir lock and related rotational arm submissions — the “twisting” descriptor flagging the rotational rather than straight-axis loading direction.
Etymology. The phrase appears in coaching vocabulary that prefers descriptive English over technique-name labels. “Twisting” specifies the rotational mechanic; “arm control” attaches the broader category. The descriptor is less specific than “Mir lock” — it can also refer to other rotational arm submissions — and is more common in spoken gym vocabulary than published instructional material.
Mechanics. The Mir lock isolates the target arm and loads the shoulder against its natural range of rotation; the connection between attacker and trapped arm is the prerequisite for maintaining the loaded position through the finishing pressure.
Cross-reference. “Mir lock” is the canonical site label; “arm crank” is a related colloquial term. Full mechanical coverage on Mir Lock.
