This exercise is a great way to help mobility and keep full function of your wrist, says Crosby. Rest your forearms on the arms of a chair so your wrists are supported by the ends of the chair’s arms and your fingers hang free. Bend your wrists back, lifting your hands up toward you, and then lower your hands back down. Repeat the lifting and lowering 5 to 10 times. Next, try some rotations. Keep your elbows in place, and rotate your forearms so your palms are facing upward. Hold for a moment, and then rotate again, turning your palms back over. Repeat 5 to 10 times.
