Answer: Your target heart rate is 50 to 85 percent of your maximum heart rate. To adjust your intensity level within your target heart rate zone is to keep your heart rate at the lower end of your recommended range if you are just starting regular exercise.
Explanation: It is the level at which your heart is beating with moderate to high intensity. To determine your maximum heart rate, take 220 and subtract your age. Gradually increase the intensity of your workouts as your fitness improves. Also, your heart rate should stay in the lower ranges during warm-up and cool-down periods.
