Nautilus Impact Leg Extension - New

The Nautilus Impact® Leg Extension is a commercial-grade strength machine designed to isolate and strengthen the quadriceps through a fully supported seated leg extension movement. Its proven biomechanics and ergonomic adjustments make it well suited for strength circuits, fitness facilities, and performance-focused training environments.

The machine uses an optimized cam and 1:1 weight ratio to provide smooth resistance throughout the range of motion. A ratcheting seat, pull-pin adjustment, and gravity-assisted positioning help users establish a comfortable and consistent training position.

The Lock N Load® weight selection system provides quick, user-friendly resistance selection, while the 5 lb incremental weight system allows for controlled progression. The Nautilus Impact Leg Extension combines reliable biomechanics with practical adjustments for efficient, focused quad training.
