The Wii Fit exercise craze comes to the DS, with Nintendo's latest attempt to make video gaming the healthiest hobby around. This unique Touch! Generations game comes bundled with two pedometers, which are able to analyse how much exercise you get from walking and jogging around each day.
Just pop one of the pedometers into your pocket or handbag and the device will collect and store the information ready for it to be uploaded to your DS. From here you can set goals for the amount of exercise you get and compare your activity to family members, friends or even your pets.
You can also post your data online and see how much exercise you're getting compared to other people from around the world. With plenty of hints and tips on whether you're getting enough or the right kind of exercise, this is the perfect way to play video games and still avoid becoming a coach potato!
