The Extreme Fitness Onyx Series Pec Fly / Rear Delt Machine delivers two essential upper-body movements in one perfectly balanced unit. Whether you’re isolating the chest or targeting those hard-to-hit rear delts, this dual-function machine provides a fluid, biomechanically accurate motion path backed by a smooth 120kg selectorized weight stack.

Designed to replicate the “must-have” feel of the classic pec deck found in elite commercial gyms, the Onyx Series model elevates the experience with enhanced ergonomics, superior component quality, and a compact footprint ideal for both home and professional training spaces.

The vertical pec fly arms feature texturized rubber grips and a spring-loaded, height-adjustable seat to lock you into the optimal pressing line. This guided arc delivers even, consistent tension through the entire range — something impossible to achieve with free-weight dumbbell flies. Expect a deeper contraction, enhanced pec recruitment, and unrivalled control on every rep.

Rotate to the opposite position and the machine transforms into a rear delt isolator using the horizontal handles. The motion encourages a perfect “open-arm” movement, allowing the rear delts to work without momentum or compensation — a major improvement over bent-over dumbbell variations where tension drops off.

Built with commercial-grade bearings, reinforced pivot points, and a smooth 120kg steel weight stack, the Pec Fly / Rear Delt machine is engineered for daily heavy use. Upholstery, padding density, and frame geometry follow the refined visual identity of the Onyx Series — sleek, modern, and unmistakably premium.
