Front tren lock
Also known as Pato Lock — the canonical term used on this site.
Training background: Informal analytical term contrasting it with the tren lock entry from behind
Colloquial — front-position tren lock variant
Front tren lock is the colloquial name for the Pato lock — using the tren-lock family relationship and “front” qualifier to flag the position context.
Etymology. “Front” specifies the position (front-facing rather than back-facing); “tren lock” attaches the leg-lock family. The compound is informal coaching shorthand that frames the Pato lock as a tren-lock-family variant.
Mechanics. The front-facing configuration loads the knee at an angle distinct from the standard rear-facing tren lock — the variant’s leverage geometry produces structural threat from a different vector.
Cross-reference. “Pato lock” is the canonical name. Full mechanical coverage on Pato Lock.
