Do this multi-duty exercise after a few hours of sitting at your desk. It will increase circulation in your legs, stretch your back muscles and improve your posture. To get started, just push your chair away from your desk so that there is nothing blocking your arms and legs.
*
1 Sit upright on the front edge of a flat, firm chair. Place your feet together, just below your knees and hang your arms alongside your body. Inhale, lift your chest and relax your shoulders away from your ears.
