The Infi-Metric was an interesting training concept which was pioneered by Arthur Jones. It involved pitting the strength of two body parts against each other. In the case of the Infi-Metric Bench Press machine shown here, as trainee pressed up one handle, the opposite handle lowered. This allowed one to train in a negative fashion in a very safe and productive manner. Because of the angles involved, it was also possible to get a stronger contraction in the chest muscles. Those who used this style of training correctly got great results, eventually becoming so strong that they bent the steel of the movement arm!
