I'm in my second work-week challenge, and this second week's challenge is more fun than last week's. Last week we had some super competitive people, so it wasn't really fun trying to get steps in. I think I'll need to work on finding the right people to "surround" myself in for the Fitbit step challenges.
The battery life on my Fitbit has been great (I have the Fitbit One). I've only charged it once in the past two weeks, and even then the batter was only down 1/3rd of the way.
It's a great piece of technology and now I need to get consistent on getting 10,000 steps in per day!
