Nautilus Impact® Leg Curl

Nautilus Impact® Leg Curl

Build stronger, more developed hamstrings with the Nautilus Impact® Leg Curl, a commercial selectorized strength machine designed for focused lower-body training. The prone leg curl position isolates the hamstrings while helping users maintain a stable, controlled movement throughout the exercise.

The Impact Strength line combines proven Nautilus biomechanics with practical user-focused features, including pre-stretch, start assist, range-of-motion adjustment, and graduated weight selection. The machine's cam-driven resistance and 1:1 weight ratio provide smooth resistance through the exercise.

The Lock N Load® weight selection system makes resistance changes simple, while the 5 lb incremental weight system allows users to make smaller adjustments for progressive training.
