Quick reference examples
Using 220 − age gives approximately 200 bpm at age 20, 190 at age 30, 180 at age 40, 170 at age 50 and 160 at age 60.
Estimated maximum heart rate ≈ 220 − age
Worked example
At age 35, the simple estimate is 185 bpm. A 70% training reference would be about 130 bpm.
Why a chart is only a starting point
Actual maximum heart rate varies by person. The chart is useful for rough planning, not as a personal medical measurement.
Common mistakes
- Assuming everyone of the same age has the same maximum heart rate.
- Using maximum heart rate as a resting target.
- Ignoring medications or health conditions that affect heart rate.
Frequently asked questions
What is the estimated max heart rate at 50?
About 170 bpm using 220 − age.
What is it at 60?
About 160 bpm using the same formula.
Should I use a calculator for an exact training zone?
A calculator makes the percentage arithmetic easier, but the underlying maximum-heart-rate estimate is still approximate.
