Problem: Leg numbness due to inactivity Solution: Stand up and get moving throughout the work day. Try to stand while talking on the phone or filing papers. Do toe lifts to increase circulation and strengthen calf muscles. Stand straight up with your feet together. Slowly, rise up on your toes. Hold the position for five seconds and then slowly roll back on your heels. Use your desk or the back of your chair for balance. Repeat the exercise several times.
