Many people spend hours each day using a computer keyboard. And typing away on a keyboard for hours each day, day after day, can take a toll on your wrists. But taking regular breaks to stretch may help prevent overuse injuries. Try this wrist press exercise to stretch your wrists. Hold your hands out in front of you and make loose fists. Then press your knuckles down toward the floor. Hold this position for 3 seconds, and then relax.
