Spinal lock
Also known as Twister — the canonical term used on this site.
Training background: Mechanical description
Descriptive — spinal-rotation joint attack
Spinal lock is the descriptive name for the twister submission — flagging the spinal column as the structural target of the rotational load.
Etymology. “Spinal” specifies the anatomical target; “lock” attaches the submission category. The label appears in coaching contexts that prefer anatomical-precision over the metaphorical “twister” or “barrel roll” names. The configuration is illegal in folkstyle wrestling (back-arch rule) but legal in submission grappling.
Mechanics. The rotation loads the cervical and thoracic spine past safe range — the truck-position leg control prevents the opponent from rotating their hips to neutralise the spinal pressure.
Cross-reference. “The Twister” and “barrel roll” are alternate names. Full mechanical coverage on Twister.
