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.

This is a low-to-medium intensity exercise
zone. This zone may be a good place to start
for those new to exercise. It's called the Fat
Burn zone because a higher percentage of
calories are burned from fat, but the total
calorie burn rate is lower.
