Leg triangle (body)
Also known as Body Triangle — the canonical term used on this site.
Training background: descriptive — distinguishes from arm/neck triangle
Descriptive — distinguishes from arm/neck triangle configurations
Leg triangle (body) is the descriptive label for the body triangle — the closed leg-figure-four configuration around the opponent’s torso, with the “(body)” qualifier distinguishing it from arm-triangle and neck-triangle configurations that also use the “triangle” geometric label.
Etymology. The compound phrase combines “leg triangle” (specifying the limbs forming the triangle) with the disambiguator “(body)” specifying the target structure. The disambiguation matters because “triangle” alone is most commonly attached to the neck-and-arm strangle, not the body-encircling configuration. The label predominates in coaching contexts that need to disambiguate explicitly.
Mechanics. The closed figure-four around the torso compresses the opponent’s body and transfers the attacker’s hip pressure through the closed leg loop — the connection is what makes the back position retainable against escape rotation.
Cross-reference. “Body triangle” is the canonical site label; “body scissors” and “figure-four leg lock” are alternate names. Full mechanical coverage on Body Triangle.
