I have been wearing a pedometer from morning until night since 2001. I record my step counts and distance daily on an Excel spreadsheet. I average the step counts monthly along with my weight and exercise minutes. This gives me concrete evidence of my trends so I can make adjustments if needed.
I used the Yamax SW-651 for years but had to replace it due to the plastic clip breaking. The stopwatch feature is handy to time my exercise sessions. Currently I use the SW-651 at the gym and the CW-701 (metal clip) on my street clothes. Step Into Health sells both series. Buy the safety strap.
