But a new study published in the Journal of the American Medical Association found that using a small and inexpensive device, called a pedometer, increased physical activity in those wearing it. The pedometer measures the number of steps a person takes. While wearing a pedometer, the average person in the study took 2,183 extra steps per day - the equivalent of an extra mile of walking.
The study also found that pedometer wearers lost weight and had improvements in their blood pressure readings.
"The results suggest that the use of a pedometer is associated with significant increases in physical activity and significant decreases in body mass index and blood pressure. Whether these changes are durable over the long term is undetermined."
