Target Heart Rate Zones Calculator
This calculator estimates your target heart rate zones for exercise based on your age. Knowing these zones can help you optimize your workouts.
Providing your Resting Heart Rate (RHR) allows for a more personalized calculation using the Karvonen formula (Heart Rate Reserve method).
To find your RHR, measure your pulse for a full minute when you first wake up in the morning before getting out of bed.
Consult your doctor before starting any new exercise program.
