Description

Designed for toning and building hamstrings and quadriceps, our space-efficient selectorized leg extension / leg curl dual station will fit your commercial fitness facility as well as it fits everyone you serve. From precise body positioning geometry to moisture-resistant cushioning to welded-steel frames, we designed every detail for performance, comfort and durability in tough, high-traffic fitness environments.

Natural Biomechanics

A refined cam profile matches the body’s natural strength curve to ensure smooth reps and consistent resistance throughout the full range of motion.

Ergonomic Upright Position

A naturally upright seated position and an optimized seat angle help users stabilize their body while allowing for the kind of targeted muscle activation that maximizes results.
