The Dynasty Fitness DSH009 Seated Hack Squat is a plate-loaded lower body machine that trains the quadriceps as the dominant muscle through a seated bilateral squat movement, using a forward-leaning back pad angle specifically engineered to minimise glute activation and concentrate the loading on the quad. A dual-axis linear guide system with two lead rails and eight roller assemblies moves the footplate carriage smoothly through the full squat range without deviation or binding under any load within the 661 lb bilateral capacity. The oversized non-slip footplate accommodates multiple stance widths, and a clearly marked safety catch lever with pop pin operation provides safe reracking for solo training at maximum effort. Built from PT60×120×2.5mm steel in matte black, the DSH009 is built for commercial gyms, physique-focused training studios, and serious home gym setups where dedicated quad isolation in a seated machine squat is a training priority that neither a standard hack squat nor a leg press delivers in the same way.

• Seated plate-loaded hack squat with a forward-leaning back pad that deliberately reduces glute involvement and concentrates the bilateral squat stimulus on the quadriceps more directly than a standard hack squat or leg press
• Dual-axis linear guide system with two lead rails and eight roller assemblies delivers carriage travel that stays smooth and jam-free under maximum bilateral plate loading at any point in the squat depth
• 661 lb bilateral load capacity across two weight horns handles any practical quad-focused squatting programme without approaching a resistance ceiling
• Oversized non-slip footplate supports the full range of stance widths and foot placements so narrow outer-quad emphasis and wide adductor-involved positioning are both accessible without moving to a different machine
