They're trying to see if they've reached an exercise target heart rate. A 40-year-old jogger, for example, would have a maximum heart rate of 180 beats per minute and an exercise target heart rate of, say, 108 beats per minute. If you have the Basis B1 band on your wrist, you'll get this information delivered automatically and, more importantly, evaluated against your sleeping and waking states. Not only that, you'll begin to understand how you transition between the various states, which can be just as revealing. All of this self-tracking may seem novel, but it's part of a movement that has gained a lot of momentum -- and attention -- in recent years. Before we take a closer look at how the sensors on the Basis B1 band work, let's go inside a trend that would make Narcissus proud. The Basis B1 band isn't a simple heart rate monitor. Most single-function heart rate monitors come with a chest-strap sensor that transmits heart rate data to a watch.
