The Nautilus Impact® Low Back Machine is a commercial strength training unit engineered to deliver controlled, effective lower back workouts using proven biomechanics and thoughtful design details. Part of the Impact® Strength line, this machine represents the evolution of Nautilus’ long-standing commitment to user comfort, safety, and performance.
The Impact® Strength series builds on features that users consistently value, including pre-stretch positioning, start assist functionality, and selectable range of motion, allowing exercisers to train with proper alignment and confidence. These elements help reduce strain during setup while supporting smooth, controlled movement throughout each repetition.
This low back machine features a user-friendly weight stack with 5 lb incremental adjustments, making it easy to progress gradually and precisely. The ratcheting seat adjustment and gravity-assisted positioning simplify entry and exit, while ensuring correct positioning for a wide range of users.
At the core of the machine is Nautilus’ patented Lock N Load® weight selection system, designed for fast, secure weight changes without disrupting the workout flow. Combined with the machine’s solid frame construction and refined movement path, the Nautilus Impact® Low Back Machine is well suited for high-traffic gyms, training centers, and rehabilitation-focused facilities that demand durability and consistent performance.
