You really have to experience the Nitro® Plus advantage to understand just how radical a difference there is between their Preacher Curl machine 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 Preacher Curl strength machines, clients get immediate, smooth resistance and proper muscle loading through the complete range of motion. The converging press arms on 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 joint rotation for increased muscle contraction.
