Become creative on ways to increase your steps. At work, go for walks at lunchtime. Go for walks with your spouse or children. Walk the dog. Walk to the store instead of driving, or park at the far end of the parking lot. Use the stairs instead of the elevator. For me, I take brisk 2-mile walks around the neighborhood twice a day everyday (aerobic walking). Just do whatever works best for you, but do it! You will need good walking shoes and socks to prevent injury when walking for exercise (like aerobic walking).
