Estimated max heart rate
180 bpm
Percent of estimated max. Resting heart rate was blank, so Karvonen was not used. A training estimate, not medical advice.
The estimate at age 40 is a max of 180 bpm, with moderate at 90–126 bpm.

| Estimated max (220 − age) | 180 bpm |
|---|---|
Moderate (50–70% of max)90–126 bpm | |
| Vigorous (70–85% of max) | 126–153 bpm |
| Method | Percent of max |
Estimated max heart rate is 220 minus age. With no resting heart rate, moderate is 50–70% of that max and vigorous is 70–85%. With a resting heart rate, the same percents apply to heart-rate reserve, then the resting rate is added (Karvonen). The scale shows those zones, plus the ranges below moderate and above vigorous. This is a training estimate, not medical advice.

How it works
- 1
Enter your age and choose male or female for the body figure. Estimated max heart rate is 220 minus that age.
- 2
Leave resting heart rate blank for zones at 50–70% and 70–85% of that max.
- 3
Enter a resting heart rate to use Karvonen instead. This is a training estimate, not medical advice.

Questions
Is this medical advice?
No. It is a training estimate from a simple formula. It does not say whether exercise is safe for you, and it is not medical advice.
What if resting heart rate is blank?
Karvonen is skipped. Zones are a percent of estimated max heart rate only: moderate at 50–70% and vigorous at 70–85%.
Where does 220 minus age come from?
It is a common estimate of maximum heart rate. Real maximums vary from person to person. Use the zone as a rough training guide.
