Clipping a pedometer to your belt each day may help you get more exercise. In fact, say researchers, people wearing pedometers increased their distance by just over 2,000 steps, or about one mile, a day. The report, published in the Journal of the American Medical Association, was based on a review of 26 studies that examined using pedometers as a physical activity motivator. Participants, mostly female and relatively inactive before they began their walking program, lost weight, decreased their body mass index and lowered their blood pressure. Having a step goal, say researchers, helped pedometer users stay motivated and improved their physical activity.
