The rotational motion engages not only major muscles like biceps and triceps but also stabilizing muscles in your forearms, wrists, shoulders, and even core. Research suggests that exercises involving multi-joint movements activate more muscle fibers compared to isolated exercises targeting individual muscles (1). By engaging multiple joints at once through continuous rotations with the power ball, you can recruit a larger number of motor units within different muscle groups – leading to greater overall muscular development. Furthermore, using this device requires constant coordination between hand-eye movements as well as fine motor skills from fingers gripping onto it tightly while maintaining speed control. These factors contribute significantly towards improving neuromuscular coordination…
