Formula: Karvonen method, with the Gulati formula for women's max heart rate.
Worth Knowing
The Karvonen method used here is more personalized than a simple percentage of maximum heart rate because it factors in your resting heart rate, which reflects your current fitness. As your cardiovascular fitness improves, your resting rate falls and your calculated zones shift, so it's worth re-checking every few weeks. Remember the zones are guides for training intensity, not medical thresholds — medications like beta-blockers can blunt heart-rate response and make perceived effort a better gauge than the numbers.
