Target Heart Rate Calculator

How the Target Heart Rate Calculator Works

Calculating your max heart rate is very easy. It's 220 minus your age.

The 60 second heart rate is 50% (for the minimum) of your max heart rate and 85% (for the maximum).

The min and max 10 second heart rate range is the 60 second (for min/max) divided by 6. For your exercise routine, you want your heart rate between the min and max - this is your most efficient exercise zone.
