The Midday Booster: It stretches your chest and shoulders, strengthens your upper back, reinforces good posture and, most importantly, promotes blood flow
1. Start by rolling your shoulders backward. 2. Next, lift your arms up and roll your shoulders back again, but this time lead with your elbows. 3. Finally, make a big circle backward with your arms. Repeat five times. You should feel your shoulder blades move as you do all three stretches.
