is widely used to calculate target heart rate zones for cardiovascular workouts. Unlike basic formulas that only use age, Karvonen considers your resting heart rate, providing a more accurate and individualized training range. This is particularly useful for athletes and individuals following structured exercise programs, especially those recovering from medical conditions or training at specific intensities.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This calculator estimates your target heart rate for exercise using the Karvonen formula.
