Spirit i-Strength Pec Fly/Rear Delt

The Spirit i-Strength Chest Fly / Rear Delt is a premium dual-purpose machine designed to target the pectorals and the posterior deltoids with absolute precision. By combining two essential upper-body movements into one space-efficient footprint, it eliminates the need for separate fly and rear-delt units. Unlike traditional cable or plate-loaded machines, the i-Strength Chest Fly Rear Delt utilises adaptive mechanical resistance to provide a perfectly smooth arc of motion, ensuring that the tension remains constant on the muscle rather than dropping off at the peak of the movement.

This Chest Fly and Rear Delt machine is a key component of the 9-piece Spirit i-Strength Range, driven by an advanced 10.1" HD touchscreen console. The digital system allows you to instantly swap between four dynamic training modes to optimise your upper-body development:

• Pure: Standard, consistent resistance for traditional hypertrophy and strength
• Eccentric: Increases the load during the "opening" phase of the fly or the "closing" phase of the delt work, emphasising the negative to build superior muscular control
• Isokinetic: Maintains a fixed speed of movement, forcing the muscles to recruit maximum fibres throughout the entire range of motion without relying on momentum
• Elastic: Simulates the feel of resistance bands, where the tension increases as you reach the end of the rep, perfect for explosive power and fast-twitch activation

Why Choose i-Strength?

The i-Strength Chest Fly / Rear Delt machine is a standout piece for luxury boutique and high-end hospitality gyms. Its sleek, curved frame and midnight-black finish provide a modern, sophisticated look. At its core is a Mechanical Servo Motor that replaces traditional iron weight stacks, delivering whisper-quiet digital resistance up to 58kg.

The machine’s smart technology provides real-time feedback through integrated LED lighting that shifts colours to represent your workload and intensity. All training metrics are captured and can be analysed later via the Spirit Connect App. Biomechanically, the machine is designed for total versatility; the dual-position handles rotate to accommodate different arm lengths and grip preferences, while the adjustable seat and range-of-motion limiters ensure you can find the safest and most effective starting point for your specific shoulder mobility.
