Nautilus Impact Deltoid Fly

The Nautilus Impact® Deltoid Fly is a commercial selectorized strength machine engineered to isolate and develop the shoulder muscles with controlled, consistent biomechanics. Designed for professional fitness environments, it delivers focused deltoid training while supporting proper posture and joint alignment throughout the movement.

The machine operates on a guided, fixed motion path, helping users maintain correct form during fly and reverse-fly style movements. Pre-stretch positioning and assisted start mechanics simplify setup and improve comfort, making the unit accessible to users across a wide range of experience levels.

A selectorized resistance system with 5-lb incremental adjustments allows for precise progression, while gravity-assisted positioning and a ratcheting seat adjustment enable fast, secure setup in busy gym settings. Depending on configuration, the unit supports unilateral or bilateral movement and converging or diverging arm paths, offering programming flexibility without compromising consistency.

Built on the Impact® Strength platform, the Deltoid Fly combines durable construction, intuitive adjustments, and refined ergonomics, making it a reliable choice for gyms, training centers, and rehabilitation-aware facilities seeking dependable shoulder isolation equipment.
