Ok, I have not actually walked the Serengeti. But I have walked the 500 miles that would represent walking from the top to the bottom of the Serengeti since I started using my Fitbit. That would be a very silly thing to do. The last time I was in the Serengeti it was very clear that I was not high enough up on the food chain to survive such a walk.
I decided to participate in a Fitbit study. It seemed like such a great deal. In exchange for giving them my blood and my ongoing activity information, I got to try the device. One of my challenges with a device is that there is a learning curve to optimally using it, and that was overcome immediately. The friendly study personnel set up my Fitbit and made sure I knew how all the features before I left with my device.
Prior to entering the study I had gotten back on the exercise bandwagon, but what I did not realize is that on days that I did not exercise for an hour I was very unlikely to achieve my baseline goal of 10,000 in a day, unless I was on vacation and walking a lot. My job is very sedentary and even though I have a standing desk, my daytime activity is shockingly low. I love my Fitbit—I faithfully meet my baseline goals except on very rare occasions, and I will be using it when the study I am in ends.
