heart rate zones

Heart rate zones are categories that represent different intensity levels of exercise based on your heart rate. They range from low to high effort, typically divided into five zones: Zone 1 (very light, recovery), Zone 2 (light, sustainable effort), Zone 3 (moderate, aerobic capacity), Zone 4 (hard, anaerobic threshold), and Zone 5 (maximum effort). Monitoring your heart rate helps tailor workouts to improve endurance, burn fat, or build strength. Staying within specific zones ensures effective training aligned with your fitness goals while avoiding overexertion. Your target zones depend on age, fitness level, and exercise objectives.
