The Nautilus Nitro Plus line is a compact, durable, and ergonomic 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 Plus 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. The Nautilus Nitro Pus line offers the same functionality and technology as Nautilus Nitro machines, but the upgraded appearance and special enhancements will definitely attract attention.
A Nautilus Nitro Plus Rotary Torso is, and can best be described as follows: A Rotary Torso is a plate-loaded or selectorized piece of exercise equipment that assists in the development of core strength by working the abdominal and back muscles when the user rotates the torso through the waist from side to side. When using a rotary torso machine the user is typically seated, with legs spread apart slightly and braced against pads, and grasps handles attached to pads placed against the upper torso.
