Fat-Burning Heart Rate: At What Intensity Should I Do Cardio To Burn Fat ?

8th April 2023

If you're looking to burn fat through cardio exercise, you might have heard about the "fat-burning heart rate". This refers to the heart rate zone where your body is thought to burn the most fat during exercise. But how do you know what your fat-burning heart rate is, and is it really the best way to burn fat? Let's take a closer look.


First, it's important to understand what your heart rate is and how it varies depending on your level of activity. Your heart rate is simply the number of times your heart beats per minute. Your resting heart rate is the number of beats per minute when you're sitting or lying down and not exerting yourself. A healthy resting heart rate is typically between 60 and 100 beats per minute, although this can vary based on factors such as age and fitness level.

As you become more active, your heart rate will naturally increase. This is because your heart needs to pump more blood to deliver oxygen and nutrients to your muscles. Your heart rate will continue to increase as you engage in more intense exercise.


So, what is the fat-burning heart rate and how do you determine it? The fat-burning heart rate is typically considered to be between 60% and 70% of your maximum heart rate. Your maximum heart rate is the highest heart rate you can achieve during exercise, and it can be estimated by subtracting your age from 220. For example, if you're 30 years old, your estimated maximum heart rate would be 190 beats per minute (220 - 30 = 190).

To calculate your fat-burning heart rate, simply multiply your maximum heart rate by 0.6 and 0.7. Using the example above, the fat-burning heart rate for a 30-year-old would be between 114 and 133 beats per minute (190 x 0.6 = 114, 190 x 0.7 = 133).

However, it's important to note that the fat-burning heart rate is not the only heart rate zone where you can burn fat. In fact, research has shown that high-intensity interval training (HIIT) can be more effective for burning fat than steady-state cardio at the fat-burning heart rate. This is because HIIT can increase your metabolism and calorie burn for hours after your workout is over.


So, what's the best way to burn fat through cardio exercise? The answer depends on your fitness level, goals, and personal preferences. If you're just starting out, it may be best to focus on low- to moderate-intensity cardio exercise, such as walking, cycling, or swimming, at the fat-burning heart rate. This can help you build endurance and burn calories without putting too much stress on your body.

As you become more fit, you can gradually increase the intensity of your cardio workouts, incorporating intervals of higher intensity. This can help you burn more calories during and after your workout, and improve your overall fitness level.

In conclusion, the fat-burning heart rate can be a useful tool for beginners looking to burn fat through cardio exercise. However, it's not the only way to burn fat, and high-intensity interval training can be more effective for some people. Ultimately, the best way to burn fat is to find a cardio exercise routine that you enjoy and can stick to consistently.
