You can calculate your maximum heart rate by subtracting your age from 220. For example, if you're 45 years old, subtract 45 from 220 to get a maximum heart rate of 175. This is the average maximum number of times your heart should beat per minute during exercise.

What is the percent of maximal heart rate method?

Target heart rate is generally expressed as a percentage (usually between 50 percent and 85 percent) of your maximum safe heart rate. The maximum rate is based on your age, as subtracted from 220. So for a 50-year-old, maximum heart rate is 220 minus 50, or 170 beats per minute.

How do you record maximal heart rate?

The traditional method, also known as HRmax, is a simple way of gauging your maximum heart rate. Start by subtracting your age from 220. Then, use the result to calculate your range. For example, if you're 50 years old, the calculation would be: 220 - 50 = 170 (HRmax).
