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.
The basic formula for calculating maximum heart rate is to subtract your age from 220. Your target heart rate during exercise ranges from 50 percent to 85 percent of your maximum heart rate, depending on the intensity of the activity.However, this method for calculating maximum heart rate and target heart rate zones might be inaccurate for well-conditioned individuals or athletes.hile the normal resting heart rate for adults ranges from 60 to 100 beats per minute, conditioned athletes and other highly fit individuals might have normal resting heart rates of 40 to 60 beats per minute.
