If you sit behind a desk for hours at a time, you are probably familiar with the aches that are common among the office workers.
In order to stay comfortable at work you need to take short breaks from sitting and following exercise may ease your pain.
It may look like you are scratching your back, but you are really stretching the back of your arm.
Reach behind your head and place your hand on your upper back, keeping your arm close to your ear.
Gently hold your elbow with your opposite hand.
Pull your elbow toward the back of your head and reach your hand toward the middle of your back until you feel a gentle stretch. Hold for 15 seconds.
Relax, and repeat on the other side.
