HS13 LEG EXTENSION

The HS13 Leg Extension is purpose-built for isolated quadriceps development in commercial gym environments. The seated extension movement targets the quadriceps femoris through a full, controlled range of motion — delivering peak contraction at full extension for maximum muscle fiber recruitment. Consistent, smooth resistance throughout the extension arc keeps tension on the quads from the starting position through to lockout, building anterior leg strength, size, and muscular definition with every rep. The stable, supportive seat keeps users correctly positioned throughout the movement, eliminating compensatory body movement and ensuring pure quadriceps isolation set after set. Built to commercial standards with a 96 kg weight stack and precision-engineered components, the HS13 handles the demands of high-traffic gym use with reliable, consistent performance every session.
