Variable resistance gets progressively lighter as the arms are retracted toward the chest in accordance with human body mechanics. A generous chest constraint pad for body-machine contact load distribution, resulting in the constraining stresses applied to the muscle bellies (not how much chest compression you can endure like incline lever rows). Using its "cross-axes technology", the machine stresses the more "lateral" aspects of the upper back muscles (contributing to the "V taper" sought after by many athletes). The machine is adjustable to different-sized operators, for easy access to the machine.
