Not all repetitive motions are equal. It's far more complex than that. The relative angles your joints are held at during the motion, rotations, etc, are far more important than just some simple metric around number of repetitions or distance travelled. Saying less motion is better is like saying lifting less weight is better. You'll sooner fuck up your back lifting 40 pounds incorrectly than 80 pounds correctly.
