Strengthen with Non-Impact Resistance
Even if your broken finger or hand has healed, the limb will still be weak once you remove your cast. For this reason, it is very important to take steps to strengthen the limb and regain lost power after injury.
Exercise with Powerball fully engages the muscles along the entire kinetic chain of the arm, strengthening from fingertip to shoulder. Unlike concentric and eccentric exercises (e.g. weight lifting, pushing your hand against a wall, etc.) exercise with Powerball is fully isometric. Isometric exercise is 100% non-impact meaning it places absolutely zero strain on sore or weak ligaments or bones. With this in mind, you need never worry about over-exerting yourself or worsening your injury when you exercise with Powerball.
