Studies show that people who use pedometers walk more on a daily basis. In this video Dr. Sallis explains how using a step counter pedometer is a great way to keep active. A pedometer senses your body motion and counts your footsteps. This count is converted into distance by knowing the length of your usual stride. Wearing a pedometer and recording your daily steps is a great motivating tool and it helps you to increase your steps toward a goal of 10,000 steps per day.
