Sitting for hours in front of a computer at work can do a surprising amount of damage to your hips, back, shoulders, and neck. You can prevent the discomfort by spending a few minutes a day on these exercises.
Problem: Hunched shoulders
Fix: Stand or sit with your arms at your sides, your feet shoulder-width apart, and your head up, facing forward. Then breathe deeply, lift your chest, and pull your shoulders back, squeezing your shoulder blades together for 3 seconds. Relax, and then repeat 10 times.
