The ONYX Flat Chest Press is a premium plate-loaded strength machine engineered for powerful, controlled chest development. Designed for commercial gyms and high-end training facilities, its motion arm path is built to align with pectoral fiber orientation and natural shoulder movement—delivering a smooth, stable press with strong target muscle activation.

Large-diameter rubber-coated handles improve comfort and reduce wrist strain, while the ergonomically angled backrest supports the scapula for better stability and pressing mechanics. With a pneumatic, infinitely adjustable seat, users can quickly dial in the optimal posture for safe, efficient training across a wide range of body types.
