The most effective heart rate zone for fat burning during exercise typically falls between 60% to 70% of an individual’s maximal heart rate. This zone, often referred to as the fat-burning zone, allows the body to utilize fat as a primary fuel source while maintaining a sustainable intensity level. Exercising within this range encourages the body to burn stored fat for energy, making it ideal for weight management. Monitoring heart rate during workouts can help ensure training intensity aligns with fat-burning goals, optimizing the effectiveness of the exercise routine.
