I have been using a Fitbit Charge 2 over the past week, with the goal being to improve fitness through measurement and digital encouragement. My iPhone already tracks steps walked, though. What else does the Fitbit offer?
Some Fitbit devices, including the Charge 2, track heart rate. This is useful for recording a measurement of intensity of exercise. And in turn, that is useful for weight management. If you enter your weight, height, and age, and if you honestly record calories eaten, the Fitbit tracks your steps and heart rate, and tells you how many calories you should eat in the day, if you want to gain weight, maintain weight, or lose weight. Rather than having a static number of calories for the day, or even a flexible number based on vague notions of “light exercise” or “moderate exercise”, the Fitbit seems to do a decent job tracking how much exercise you actually get and adjusting remaining calories accordingly.
The outboard Fitbit software (on iOS or web or whatever) provides opportunities to connect with other Fitbit users for good-natured competition, alerting you that “Oscar has almost caught up with you!” or “Laura has completed her step goal for today!” and so on. Even when not connected with any other users, you get alerts and electronic “badges” for various fitness achievements. Both of these, while happening entirely in the digital realm, are surprisingly motivational.
When using the iPhone to track my steps, I would make sure to grab it before going on what I knew to be a long-ish walk, but I would routinely leave it charging at the computer when going on shorter excursions. The Fitbit is more conveniently always with me, taking the place of a wristwatch.
So far, the step counter seems reasonably accurate to me. Extreme arm movements can trigger a false step, but apparently I don’t do much of that when not actually walking (or at least exercising). It does, however, record arm movement when playing the piano as steps; a few days ago, it recorded about 2000 false steps before I took it off and put it in my pocket. Now I know to just take it off before playing the piano.
Curiously, there is no way to turn it off, and no easy way to get it to pause in recording steps. A simple on-device click for that would be a preferred solution, if I were about to engage in activity for which I knew it would record false steps.
A week in, I am finding the Fitbit a great tool for tracking and improving fitness. Now I would like a similar tool for tracking and improving at other things too!
