Walk, walk and more walking: Walk wherever and whenever you can during the day. It will burn a few extra calories and help you lose weight without the pain and difficulty of running. It's very easy to fit into a workday. If you take an elevator to your office, try taking the stairs. If you normally make phone calls at your desk, try getting up and walking around the office while you're talking. Sitting for long periods of time can slow your metabolism, so getting up out of your chair, walking on the spot and stretching can contribute to your weight loss.
