Your Heart Rate Zones

Professional Note: Heart rate zones are calculated using the Karvonen formula (Heart Rate Reserve method) for better accuracy, based on your age-predicted maximum heart rate (220 - age) and resting heart rate. Individual variations exist. For precise training zones, consider getting a professionally administered exercise stress test. Always consult with a healthcare professional before starting a new exercise program, especially if you have any medical conditions.
