The Alta HR Wristband is Fitbit’s slimmest heart rate monitor, and while it’s an excellent choice for fitness training, you’ll end up wearing it a lot more than just at the gym, on the treadmill, or at the track. Its PurePulse obviously shines when you’re working out thanks to better calorie burn tracking and more insight into your health than any Fitbit band has ever offered before, but Alta’s SmartTrack auto-recognition also records how many miles you walked or commuted for a complete registry of your overall fitness.
