Check Your Heart Rate; Default Heart-Rate Zones - Fitbit Zip Ionic User Manual

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.

Description
Your heart rate may be elevated, but not
enough to be considered exercise.
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.
