Check your heart rate

Heart-rate zones help you target the training intensity of your choice. Ionic shows
your current zone and progress toward your maximum heart rate next to your heart-
rate reading. 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.
