If you spend long hours at a computer, this stretch is for you! The muscles in the forearm cross the wrist via the carpal tunnel; when tight, they can cause pain in the wrist and hand. Stretch them by holding your arm out in front of you, palm facing up. Keeping your elbow straight, bend your wrist back so that your fingers point toward the floor. Use your other hand to increase the stretch by pulling back on your palm. Hold the stretch for at 30 seconds or until a release is felt, then repeat on the other side.
