This speedy relaxation exercise, which can be done sitting or standing at your desk, is a quick fix for tense wrists.
First, move any objects such as your keyboard and other items on your desk in front of you out of the way. Place your elbows on the desk. Lift your underarms and hands to your shoulders and let your thumbs touch your shoulders. Then let your arms and hands drop heavily on to the table. Allow your underarms and hands to be so heavy they make a sound when landing on the desk. Repeat this movement three to five times to release the tensions in your arms, wrists and hands. End the relaxation exercise by shaking your arms.
