Sit straight with your shoulders relaxed. Inhale and squeeze your shoulders up toward your ears. Hold tightly for several seconds and relax as you exhale. Repeat several times.
Sitting straight, exhale and let your neck drop forward. Relax for about 2 seconds, then lift your head to the center.
Let your head drop to one side, relax, and return to center. Repeat to the other side.
Do the whole sequence 5 to 10 times, the more often the better.
Stretch Your Spine
Sit straight in your chair. With your hands clasped behind your head, exhale and turn slowly to the right.
Look behind you, twisting as far as comfortable without strain. Hold for several seconds, and inhale as you return to the starting position.
Repeat on the other side. Repeat for 10-20 times, up to 3 times a day.
