There is a mechanical advantage in utilizing rotating handles as they maneuver in three planes. The sagittal plane allows for forward and backward movements, frontal plane which governs movements side-to-side and the transverse plane that allows twisting and rotating.
Handle rotation reduces strain on the hands grasp. Thus, the lifter can apply more force to the targeted musculature. Being able to maintain a firm unobstructed grip, not fighting the palms surface friction enables the lifter to move more weight with less joint stress adding overall development to the selected anatomical region.
Moving forward or backwards or side-to-side or twist following the final repetition on an exercise can aid in more muscular fiber recruitment and help accelerate progressive overload when needed. A well designed machine with the correct strength training action for a selected body part is made to fit almost every individual, yet we are all structurally different and adding a little rotation can make it the perfect fit to Get Strong.
