The Nautilus Nitro Leg Extension is designed to deliver precise, effective quadriceps training with biomechanics that support full knee extension and optimal muscle contraction. Engineered to maintain proper axis alignment throughout the movement, this selectorized machine allows users to achieve a maximum range of motion while reducing unnecessary joint stress.

Classic full-range variable resistance cams provide smooth, consistent loading from start to finish, ensuring strong quad engagement through every repetition. A quick-set leg pad makes it easy to achieve proper positioning for users of all sizes, while the heavily padded movement arm roller and traditional seat pads enhance comfort during training. Ergo Grip® handles offer added stability and control throughout the exercise.

Built with durable 2" × 4" steel frame construction, the Nitro Leg Extension is made to withstand high-use commercial environments. The partially shielded weight stack features 5 lb increments, allowing for quick, convenient resistance changes without interrupting workout flow.
