Nautilus Impact® Kneeling Leg Curl

Nautilus Impact® Kneeling Leg Curl

Build stronger hamstrings with the Nautilus Impact® Kneeling Leg Curl, a commercial selectorized strength machine designed to train the hamstrings from a kneeling position. The unique positioning keeps the hips extended while supporting focused posterior-chain training through a controlled leg-curl movement.

The Impact Strength line combines proven Nautilus biomechanics with practical user-focused features such as pre-stretch, start assist, range-of-motion adjustment, and convenient weight selection. A true 1:1 weight ratio provides consistent resistance throughout the exercise.

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

• Kneeling Leg Curl Movement – Targets the hamstrings from a kneeling position with the hips extended.
