This maximum rate is based on the person's age. An estimate of a person's maximum age-related heart rate can be obtained by subtracting the person's age from 220. For example, for a 50-year-old person, the estimated maximum age-related heart rate would be calculated as 220 - 50 years = 170 beats per minute (bpm).
Many believe that the ideal maximum heart rate for a workout should be about 80 percent of the maximum for your age. In other words, multiply your maximum heart rate by .80 and you'll get the ideal heart rate for a workout, also known as your target maximum heart rate. So for the aforementioned 40-year-old, his target maximum heart rate would be 144 beats per minute, or 180 x .80.
