Frequently Asked Questions
What is a normal resting heart rate?
A normal resting heart rate for adults is 60-100 beats per minute. Well-trained athletes may have a resting rate of 40-60 bpm. Consistently high or low rates should be discussed with a doctor.
How do I calculate my target heart rate zones?
First estimate maximum heart rate (roughly 220 minus age). Fat burning zone is 60-70% of max, aerobic zone 70-80%, anaerobic zone 80-90%. The Karvonen formula uses resting heart rate for more accuracy.
What is the Heart Rate Calculator?
The heart rate calculator computes the maximum heart rate and optimal training zones for endurance exercise.
How does the Heart Rate Calculator work?
Enter your age and optionally your resting heart rate. The maximum heart rate is estimated using the formula 220 minus age. Training zones (base, fat burning, endurance, anaerobic) are computed as percentage ranges of HRmax.
Key Data and Facts
HRmax approx. 220 - age. Fat burning: 60-70% HRmax. Endurance: 70-80%. Anaerobic: 80-90%. Resting heart rate: 60-100 bpm (athletes: 40-60 bpm).
