Some of you might be wondering what is Fitbit? I know I did when I first saw it. It looked like those rubber awareness bands with LED lights. But after a bit of research I found that it is quite the cool contraption. Fitbit is an activity tracker that measures your sleep, exercise and diet. The nifty band will be your constant companion so you can be informed about your activity levels, be motivated to keep moving. Fitbit is simple, comfortable and useful, and you’ll be excited to check your daily progress.
