Check your heart rate
Alta HR allows you to view your real-time heart rate and your resting heart rate on
your tracker. To view your heart rate, tap your tracker until you get to the heart rate
screen where you’ll see your current heart rate. Tap again until you get to the
resting heart rate screen to see your resting heart rate. You must turn on the resting
heart rate screen in the Fitbit app.
Using heart-rate zones
Heart-rate zones help you target the training intensity of your choice. Your tracker
shows your current zone beside your heart rate, and on your Fitbit dashboard you
can see your time spent in zones during a particular day or exercise. Three zones
based on American Heart Association recommendations are available by default, or
you can create a custom zone if you have a specific heart rate you’re targeting.
Default heart-rate zones
Default heart-rate zones are calculated using your estimated maximum heart rate.
Fitbit calculates your maximum heart rate with the common formula of 220 minus
your age.
