What heart rate zone is typically targeted for fat burning?

The heart rate zone typically targeted for fat burning is the one that falls within 60-70% of maximum heart rate. This zone is often referred to as the "fat-burning zone" because it is believed that exercising at this intensity allows the body to preferentially use fat as a fuel source for energy.

When you are in this moderate intensity zone, the body is capable of providing enough oxygen to support fat oxidation, which is the metabolic process by which fatty acids are broken down. This is particularly effective because, at this intensity, the body is not so heavily relying on carbohydrate stores, allowing for a greater proportion of fats to be utilized for energy.

Exercising in this heart rate range is often sustainable for longer periods, which can extend the time spent in this optimal fat-burning state. In contrast, higher intensity zones (such as 70-80% of maximum heart rate) primarily utilize glycogen (carbohydrates) as the main energy source, which is less effective for fat burning during the duration of the activity.

By understanding the specifics of heart rate zones and their impact on energy metabolism, individuals can tailor their workouts to align with their fitness goals, whether they are seeking to lose weight, improve endurance, or enhance overall cardiovascular
