Worked example
At age 40 the estimated maximum is 220 - 40 = 180 bpm, so Zone 2 at 60-70% is 108 to 126 bpm.
What this tool does not do / Limits
General estimates only, not medical advice. The 220-minus-age formula is a rough population average and can be well off for any individual; stop and seek medical advice if exercise causes pain, dizziness or breathlessness.
Frequently asked questions
What does Zone 2 feel like?
Easy aerobic effort: you can talk in full sentences but you are clearly working, not strolling.
Is 220 minus age exact?
No. It is a rough average, and individual maximums vary widely, so treat the range as a starting guide, not a prescription.
