What is a normal heart rate during exercise?
Heart rate during exercise varies depending on the intensity of the activity. To lose weight through exercise, you should aim to reach your target heart rate, which is 60 to 80 percent of your maximum heart rate, or the most heart beats per minute possible, according to the Cleveland Clinic. To find your maximum heart rate, subtract your age from 220. For example, a 30-year-old person has a maximum heart rate of 190 beats per minute.
