What is the Target Heart Rate Calculator?
Your target heart rate tells you how hard your body is working during exercise. Enter your age and resting heart rate, pick the training zone you are aiming for, and the calculator returns your exact bpm range using the Karvonen (heart-rate reserve) formula.
Choose “All zones” for a full breakdown from gentle warm-up through fat burn, cardio and maximum effort. Check with your doctor before starting a new exercise plan, especially if you have a medical condition.
