Nautilus Impact Leg Extension (Side Mount)
The Nautilus Impact Leg Extension isolates the quadriceps through a fully supported seated extension, helping users build strength for walking, running, jumping, and squatting. Designed to reduce stress on the knees while maximizing quad engagement, it features an optimized cam and 1:1 weight ratio to deliver smooth resistance through the full range of motion. With Lock N Load® weight selection and ergonomic adjustments, it’s ideal for building leg-focused strength circuits.
