Calories Burned

Calculate the Calories Burned By Heart Rate

Burning more calories become easier with a better knowledge of the connection between the heart rate and the metabolism process.

The Fat Burning Zone

When it comes to exercise, particularly cardio exercise, there are different heart rate zones that equate to different levels of intensity.

These different levels of intensity actually determine which energy systems your body uses during exercise and that often directly affects how many calories you burn.

Hight Intensity Group (75%) 140 260 400

We usually look at four different heart rate zones when it comes to exercise, a percentage of your maximum heart rate (MHR):

  • Low intensity, also known as the ‘fat burning zone’ is 60% to 70% of your maximum heart rate and usually considered light cardio or warm-up level.
  • Moderate intensity is 70% to 80% of your maximum heart rate or a level at which you’re working but you can still talk.
  • High-intensity exercise is 80% to 90% of your maximum heart rate, putting you well out of your comfort zone and pushing your anaerobic threshold.
  • Maximum effort is 90% to 100% of your maximum heart rate, something for very advanced exercisers, athletes, and professionals.

From these numbers, you can see that the fat burning zone is the lowest intensity.
