Stand with your feet shoulder width apart. Raise your arms out at your sides and up to your shoulder level. Make a gentle fist with each hand and keep your neck relaxed. Rotate your shoulders forward, making tiny circles with arms. Do this for 2-3 minutes. Then reverse the direction and rotate your shoulders backward, making small circles with your arms. Do this for 2-3 minutes.
When doing this exercise, do not let your arms go below your shoulders. Keep your shoulder, elbow and wrist in a straight line.
