“Fat Burning” Heart Rate

Your heart rate can help you measure the intensity of your exercise. For most people, the heart beats between 60 and 100 times a minute while at rest. Heart rate increases during exercise. The harder you exercise, the more your heart rate will increase.

When you work out in your fat-burning heart rate zone, the idea is that your body taps into fat stores for energy instead of using basic sugars and carbohydrates. This leads to fat loss. Other heart rate zones are:

  • resting heart rate
  • moderate heart rate
  • target heart rate
  • maximum heart rate

Your fat-burning heart rate is at about 70 percent of your maximum heart rate.

Your maximum heart rate is the maximum number of times your heart should beat during activity. To determine your maximum heart rate, subtract your age from 220.
