Nautilus Impact Range Leg Extension

The Nautilus Impact Leg Extension is engineered to deliver safe, effective, and isolated strength training for the quadriceps. Perfect for users of all fitness levels, this machine supports the thighs and lower back throughout the movement to reduce knee strain and encourage proper form.

Built with an optimised cam profile and a true 1:1 pulley ratio, it provides smooth, even resistance across the entire range of motion — ideal for strength-building exercises that support walking, running, jumping, and squatting. With Lock N Load® pinless weight selection, the Nautilus Leg Extension is fast, intuitive, and reliable in high-traffic gym environments.
