GeoPalz Activity Tracker
The pedometers come in cute and cool styles -- think rock 'n' roll, fantasy, sports and more -- and they allow parents to track steps, weight, height, calories burned and calories consumed for the entire family. Just log everyone's steps on the GeoPalz website, and they'll be converted into points that that can be redeemed for prizes and certificates.
Teach 'em early that fitness is fun seems like a pretty great idea to us.
