TRUE PLS 1300T Plate Loaded Standing Leg Curl

The TRUE PLS 1300T Plate Loaded Standing Leg Curl is a commercial machine that trains the hamstring muscle group through a standing, unilateral or bilateral leg curl movement with Olympic weight plate loading. The standing position changes the mechanical loading profile of the hamstring compared to the prone or seated curl alternatives, producing greater tension in the proximal hamstring region — the area most often involved in hamstring strains at the muscular-tendinous junction in athletes.

The hamstrings — biceps femoris long and short heads, semitendinosus, and semimembranosus — are the primary movers in knee flexion and a critical contributor to hip extension during sprinting, jumping, and change-of-direction movements. Inadequate hamstring strength relative to quadriceps strength (a low hamstring-to-quadriceps ratio) is consistently identified as a risk factor for hamstring strain injury across multiple team and individual sports.

TRUE has constructed the PLS 1300T with the heavy-gauge steel frame and precision lever mechanics of the PLS series. The adjustable pad positions the load application point optimally relative to the ankle and calf for users of different leg lengths, and the support structure provides stable anterior and lateral bracing for the standing hip to prevent unwanted torso compensation during the leg curl movement.

The plate-loaded format of the PLS 1300T is particularly valued in sports performance and rehabilitation contexts where precisely calibrated loading is required for testing or for systematically loading the healing hamstring tendon during return-to-sport protocols following hamstring injury.

The PLS 1300T completes the lower-body plate-loaded training capability in TRUE's PLS series alongside the leg press, leg extension, and squat press machines, providing facilities with a comprehensive plate-loaded lower-body development system.
