Frequently asked questions
- What is the Karvonen method?
- It uses your heart rate reserve (max minus resting) to set target zones, giving a more personal range than a simple percentage of max.
- Are these zones medical advice?
- No. Results are estimates only and not medical advice. Adjust intensity to how you feel and consult a professional if unsure.
