Looking for a fun and helpful way to exercise? Personal Trainer Walking tracks users" progress and makes going for a walk a little more fun. It comes with two Activity Meters! Simply place the Activity Meter in your pocket or bag (or attach it to your belt with the included Activity Meter Clip Connector) and carry it around with you as you go about your daily routine. If the number of steps you"ve recorded in one day exceeds your daily step target, the light on the Activity Meter will change from red to green. You then transfer the data recorded by the Activity Meter to the Infrared Game Card. Once the data has been transferred, you can see the results on your Nintendo DS system and check your life rhythm! The Activity Meter will track your daily step count minute by minute, so you can take a look at any day and check your activity with a number of graphs. Up to five years of records can be saved on the calendar, giving you a clear portrait of your life rhythm over time—you can even write and save notes.
