Pedometers are Great Exercise Partners. As a clip-on accessory, these devices count your steps, distance and speed. Some models display heart rate, or time of day, while they count your steps. You can work out anywhere, anytime, and know all of your important work out stats. The clamshell design prevents any accidental resetting during exercise. Simply press the top of the pedometer and it opens displaying the amount of steps taken. This is one of our most popular pedometers.
