Nautilus Nitro Plus Abdominal

  • Four-bar linkage provides a moving axis of rotation that simulates the body's moving axis of rotation, increasing user  safety    
  • Combination of elbow and back pads with hand grips provide upper body stabilization, eliminating lower back muscles' static  involvement    
  • Leg anchoring ankle pads provide lower body stabilization   
  • Controlled motion movement arms isolates abdominal sheath, eliminating hip flexor involvement


You really have to experience the Nitro® Plus advantage to understand just how radical a difference there is between their Abdominal and other similar fitness equipment. During any exercise, an individual’s strength varies at different points. Other weight machines don’t even attempt to address this strength curve — instead, the weight remains constant from beginning to end. For the user, this can limit muscle recruitment and overall performance.


This unique technology is cutting edge. Driven by their trademark four-bar linkage system, cam design, or a combination of both, this dynamically matches the body’s potential increases and decreases in strength. 


With Nitro® Plus Abdominal, clients get immediate, smooth resistance and proper muscle loading through the complete range of motion. The converging press arms this line of fitness equipment provides the correct way to work out, leading to unprecedented results. The alternative strength training machine designs force the user to follow an incorrect path or motion. Additionally, the independent converging press arms also ensure greater shoulder joint rotation for increased muscle contraction.
