Seated Back Stretch
A simple exercise that can be done on any chair (even an office chair!) as well as on the exercise ball.
Start by sitting on an exercise ball or a chair. Lean forward slightly and rest your forearms on your thighs.
Now let your head drop down and round out your upper back. You should feel this mostly between the shoulder blades and into the neck. Hold for 5 seconds, relax, then repeat 3 – 5 times
