Frequently Asked Questions
How do you calculate your maximum heart rate?
A standard baseline formula to estimate your maximum heart rate is: Max HR = 220 - your age.
What heart rate zone is best for burning fat?
The fat-burning zone typically sits at 60% to 70% of your maximum heart rate, occurring during moderate cardiovascular exercise.
What is the Karvonen method for heart rate calculation?
The Karvonen formula calculates target zones by incorporating your resting heart rate to find your overall heart rate reserve.
What does a normal resting heart rate look like for adults?
A typical resting heart rate for healthy adults ranges between 60 and 100 beats per minute.
Why do endurance athletes have lower resting heart rates?
Athletes have lower resting heart rates because their cardiovascular training strengthens the heart muscle, allowing it to pump more blood with each beat.
