Modified inside heel hook
Also known as Junny Lock — the canonical term used on this site.
Training background: Descriptive term emphasising the mechanic modification from standard IHH
Descriptive — modified inside heel hook variant
Modified inside heel hook is the descriptive name for the Junny lock — using “modified” to flag the variant as a modified version of the standard inside heel hook attack.
Etymology. “Modified” specifies the variant nature; “inside heel hook” attaches the parent submission family. The compound predominates in coaching contexts that frame the Junny lock as a structural modification rather than a stand-alone technique.
Mechanics. The modification typically involves a forearm-anchored grip variant of the standard heel hook — the loading axis remains the same but the grip configuration shifts.
Cross-reference. “Inverted heel hook variant” and “Forearm heel hook” are alternate names. Full mechanical coverage on Junny Lock.
