I've been using a pedometer for about a little under two years now. I've used it everyday consistently with the exception of one day, March 8 of last year, when I was sick with a bad cold. Every day since then, I've gotten at least 10,000 steps.
Now that I'm in my next phase of my workouts, I'm thinking of giving up the pedometer. I know I do a lot everyday and I do get the required steps in. I'm thinking maybe I should wear it on days that it's tough for me to get all the steps in, just for accountability on those days.
