Answer:

To calculate your maximum heart rate, subtract your age from 220. To calculate your target heart rate (THR) zone, multiply your MHR by 64% and 76%. These numbers give you the low and high numbers that your heart rate should stay within the majority of time while you are exercising at a moderate intensity level.
