Frequently Asked Questions
What is the Karvonen method?
The Karvonen method uses your Heart Rate Reserve (max HR minus resting HR) to calculate more personalized training zones than simple percentage-of-max methods.
How do I find my resting heart rate?
Measure your pulse first thing in the morning before getting out of bed. Count beats for 60 seconds. Repeat 3 days and average the results.
