The Nautilus Nitro line is a compact, durable, and ergonomic 26-piece line of variable resistance selectorized strength machines designed to adapt to the way the body moves for more efficient performance and quicker results. Nautilus Nitro equipment utilizes Optimal Strength Curve Technology, which ensures smooth resistance and correct muscle recruitment through the entire movement, as well as dynamically matches the user's strength curve through a patented four-bar linkage mechanism and converging axis movements. The partially shielded weight stacks are seat-accessible and bright yellow adjustment knobs are easy to identify and user-friendly.
