Most of us get back pain at some point in our lives. One surprisingly simple strategy can go a long way to alleviating back pain: Paying attention to your posture.

Harvard Medical School gives these imagery and exercise tips to improve your posture:

Imagery: Think of a straight line passing through your body from ceiling to floor (your ears, shoulders, hips, knees, and ankles should be even and line up vertically). Now, imagine that a strong cord attached to your breastbone is pulling your chest and rib cage upward, making you taller. Try to hold your pelvis level — don’t allow the lower back to sway. Think of stretching your head toward the ceiling, increasing the space between your rib cage and pelvis. Picture yourself as a ballerina or ice skater rather than a soldier at attention.

Shoulder Blade Squeeze: Sit up straight in a chair with your hands resting on your thighs. Keep your shoulders down and your chin level. Slowly draw your shoulders back and squeeze your shoulder blades together. Hold for a count of five; relax. Repeat three or four times.

Upper-Body Stretch: Stand facing a corner with your arms raised, hands flat against the walls, elbows at shoulder height. Place one foot ahead of the other. Bending your forward knee, exhale as you lean your body toward the corner. Keep your back straight and your chest and head up. You should feel a nice stretch across your chest. Hold this position for 20-30 seconds. Relax.

Arm-Across-Chest Stretch: Raise your right arm to shoulder level in front of you and bend the arm at the elbow, keeping the forearm parallel to the floor. Grasp the right elbow with your left hand and gently pull it across your chest so that you feel a stretch in the upper arm and shoulder on the right side. Hold for 20 seconds; relax both arms. Repeat to the other side. Repeat three times on each side.
