The ONYX Pendulum Squat is a premium plate-loaded strength machine engineered for powerful lower-body development with smooth, joint-aligned squat mechanics. Built for commercial gyms and high-end personal training studios, its reinforced construction maintains exceptional structural stability under heavy loads for precise power delivery throughout the full squat range. The movement arm follows a trajectory aligned with natural lower-body joint motion for controlled, comfortable squatting performance. A professionally angled backrest provides firm support while minimizing lower-back pressure, and high-resilience shoulder pads reduce discomfort under heavy weight-bearing loads. Dual handle positions allow users to switch grips based on preference for improved control. Safety is enhanced with a prominently placed safety hook and a 12-position adjustable safety stop to accommodate different heights, leg lengths, and range-of-motion needs. An innovative counterbalance system allows users to adjust the machine’s base resistance, making it suitable for both beginner and advanced training. A large 5-position adjustable anti-slip footplate supports multiple stance widths and dorsiflexion angles for improved stability and targeted muscle 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 Pendulum Squat: Built for intense lower-body training with smooth, stable squatting mechanics and guided power output.
