To find your maximum heart rate, subtract your age from 220. For example, if you are 40 years old, your maximum heart rate is 180 (that is, 220 - 40 = 180). Multiplying this by 50 percent and then 85 percent results in your target heart rate range of 90 to 153 beats per minute.
This has to do with how fit you are and your maximum heart rate, which is 220 bpm minus your age. For example, if you are 30 years old, your maximum heart rate would be 190 bpm (since 220 minus 30 equals 190).The American Heart Association recommends that you do exercise that increases your heart rate to between 50 and 85% of your maximum heart rate.This range is your target heart rate zone. They recommend getting at least 30 minutes of moderate to vigorous exercise most days (or a total of about 150 minutes a week).his has to do with how fit you are and your maximum heart rate, which is 220 bpm minus your age.
