Your target heart rate is actually a heart rate range in which you seek to exercise to meet certain fitness goals. For example, if you are an athlete who wants to improve anaerobic fitness, you might train using an intensity that puts you at a number of heart beats per minute that is 80 to 90 percent of the maximum heart rate you can sustain.
The basic way to calculate your maximum heart rate is to subtract 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 maximum number of times your heart should beat per minute during exercise.
