Last but not least, you use the supplied plastic clip to attach the Fitbit Zip to your person, and then you are up and running (or walking, as the case might be). Thereafter, the Fitbit keeps track of every step you take.
Once every 20 minutes or so it synchronizes itself with your PC. If your PC is turned off or is out of range, your Fitbit will just try again 20 minutes later. Whenever you feel like doing so, you tap the screen of your Fitbit to cycle through a series of displays showing things like the number of steps you've taken thus far this day (the goal is 10,000 steps each day), the number of calories you’ve burned, and so forth. You can also bounce over to the Fitbit website to see your own personal dashboard showing all of this information as illustrated below:
The above image shows only my daily values. You can also see your cumulative totals along with a bunch of other information. Also, as another illustration as to how simple everything is, your Fitbit resets itself back to zero at midnight without you having to do anything at all. (Don't worry, it will still remember any unsynchronized values from the previous day(s) and upload them to your PC the next time they link up.) There are also lots of other cool features, like the ability to form/join groups with other users and then compete against each other.
My Fitbit Zip has proved to be a real motivator to me. I'm once again using the Treadmill Desk in my office every day while performing tasks like answering emails and taking part in online chats. I'm also parking my truck further away from things like supermarkets and malls so as to get a few more steps towards my daily total. Yesterday, for example, while changing planes at Dallas airport, I walked all the way from Gate 37 at the far end of Terminal D to Gate 9 at the far end of Terminal A (this is not a short walk).
I actually ended up getting more exercise than I expected, because when I finally reached Gate 9 in Terminal A, I discovered that there had been a gate change and my flight was now departing from Gate 38 in Terminal A -- I gate I'd walked past quite some time ago. "Oh dear," I said to myself (or words to that effect).
In conclusion, I have to say that I'm very, very impressed. This is such a simple concept, but it's certainly got me doing significantly more exercise (in the form of walking) than I was doing before. The main thing for me is that it's so easy to use. All I have to do is make sure I'm wearing it -- I don’t even have to turn it on and off. How about you? What motivates you to get out of your chair and do some exercise?
