What is the recommended heart rate zone for maximum fat burning during aerobic exercise?

The recommended heart rate zone for maximum fat burning during aerobic exercise is typically between 60-70% of maximum heart rate. This zone is often referred to as the "fat-burning zone" because it is at this intensity that the body utilizes fat as a primary source of fuel more efficiently compared to carbohydrates.

Exercising within this heart rate range encourages the body to draw on fat stores rather than glycogen, which is more readily used at higher intensities. This moderate level of intensity typically allows for sustained aerobic activity while still being manageable for most individuals, making it ideal for longer-duration workouts aimed at enhancing fat oxidation.

As intensity increases beyond this zone, the body tends to shift its energy utilization more towards carbohydrates, which, while beneficial for performance and endurance, may not optimize fat burning as effectively. Therefore, training within the 60-70% range is strategically beneficial for those focusing specifically on fat loss during aerobic exercise.
