Does anyone else use a fitness device like the Fitbit to track your daily steps/mileage? I borrowed a friend's Fitbit Flex to track how much I walk during a shift. In a 4 hour preload shift I have been averaging 6-8 miles while loading 4 package cars. Before I buy such a device - does anyone have any suggestions? I'm not that concerned with the calorie intake and such. I mainly want to keep up with my distance. Also, any drivers use anything like this? I've just seen that my device does calculate some extra steps while driving my personal vehicle. Haven't had the chance to try using it while cover driving.
