The ideal heart rate zone for burning fat during exercise is typically around 60-70% of maximum heart rate. At this intensity, the body utilizes fat as a primary energy source, promoting effective weight management and improving cardiovascular fitness. Exercising within this zone encourages efficient metabolism and supports endurance training. To determine individual heart rate zones, one can calculate maximum heart rate by subtracting age from 220, ensuring personalized exercise intensity aligns with fat-burning objectives.
