Part two of a first-person experiment: Two weeks with the Fitbit Flex exposes the power, and the limits, of wearable fitness tracking devices.
Since living with the Fitbit, I am far more consciously aware of everything I do that even remotely affects my health. Wearing a tracker makes you think about how often you opt for the elevator, how full your plate is at every meal, and how much sleep you get on a daily basis. While I'm not neccesarily eating any better, I'm becoming more aware of what I eat too often (bagels) and not enough (anything green).
On the flip side, since wearing the tracker I've been sleeping more - and I feel that I've been sleeping better. Before using the Flex I'd been down to about five to six hours a night. And my sleep efficiency for the last two weeks has risen to a pretty stellar 94%.
