ONYX Seated Hack Squat

$3,499.00
By VO3 Fitness

The ONYX Seated Hack Squat is a premium plate-loaded strength machine engineered for focused lower-body performance and quad-dominant squat training. Designed for commercial gyms and upscale training studios, its modern aesthetic and reinforced construction are matched with a high-precision dual-axis linear guide system for an exceptionally smooth, stable squat path.

Ergonomically optimized seat and backrest angles support natural hip-knee coordination during the squat movement. The forward-leaning back pad provides firm torso support while maintaining ideal hip flexion—minimizing glute compensation and intensifying quadriceps engagement. A clearly marked safety catch lever allows quick, effortless operation for secure training, while the oversized non-slip footplate supports multiple stances and heights for comfort, stability, and full range of motion.
