We got these pedometers, and I'm working mine out. I have found that if you shake your hips Shakira-style, that little counter gets to jumpin', jumpin'.
All the activity that I do, from regular walking to exercising and "weighing in" at HR, gets recorded, and I get points for each thing. After so many points, I will start accumluating money toward gift cards of my choice (to places like Target and Amazon).
Just wait 'til it gets warm outside. This pedometer will be in for the ride of its life.
