The ONYX Hack Squat is a premium plate-loaded strength machine engineered for powerful lower-body development with exceptionally smooth, stable squatting mechanics. Built for commercial gyms and high-end personal training studios, its sleek modern design and solid structural integrity deliver reliable performance for high-traffic training environments. A precision dual-axis linear bearing system ensures a fluid, natural squat trajectory with consistent force output—minimizing vibration and preventing jamming even under heavy loads. High-resilience shoulder pads with an ergonomic tilt reduce pressure during weight-bearing, while a wide backrest and contoured headrest provide secure body support for improved comfort and safety. A prominently placed safety hook control lever enables quick engagement, and a five-level adjustable bottom stop allows users to customize squat depth for different heights and mobility levels. An oversized dual-angle anti-slip footplate supports multiple stances and ankle flexion angles, improving accessibility and enhancing quad and glute engagement. .accordion-section { margin-bottom: 10px; border: 1px solid #ddd; border-radius: 6px; overflow: hidden; } .accordion-label { display: block; background-color: #f7f7f7; padding: 12px; font-weight: bold; cursor: pointer; } .accordion-content { max-height: 0; overflow: hidden; background: #fff; padding: 0 12px; transition: max-height 0.4s ease, padding 0.4s ease; } input.accordion-toggle { display: none; } input.accordion-toggle:checked ~ .accordion-content { max-height: 4000px; padding: 12px; } .accordion-content ul { margin: 0; padding-left: 20px; list-style-type: disc; } Key Features Plate-Loaded Hack Squat: Built for intense lower-body strength and controlled squat mechanics.
