Nautilus Impact® Low Back

The Nautilus Impact® Low Back is a commercial strength machine designed to strengthen the spinal erectors and posterior chain through controlled, seated back extension movement. Its supported positioning makes it well suited for focused lower-back training and commercial strength circuits.

The machine features a dynamic strength curve with a true 1:1 weight ratio, providing consistent resistance throughout the movement. Pull-pin adjustment and gravity-assisted positioning help users establish an effective training position.

The patented Lock N Load® weight selection system allows for quick and convenient resistance changes, while the 5 lb incremental weight system supports gradual progression. Its practical design makes the Impact Low Back a versatile addition to total-body circuit training.
