My daily Yoga Tune Up® Therapy Ball routine always includes a roll out for the upper back. My day involves driving in the car, teaching, and sitting (or standing) at my desk. All activities are in front of me, which makes it very tempting to slouch! My upper back tends to be very tight and knotty, as it is with many people who also drive or work at a computer all day. A quick rub down for the upper back will helps to refresh and rehydrate these overworked muscles.
