How to use it
- 01Enter your age.
- 02Review the estimated maximum heart rate plus moderate and vigorous zones.
- 03Use the detailed warm-up, aerobic, cardio, and peak bands for training guidance if they fit your program.
Result guide
- The age-based maximum-heart-rate formula is an estimate, not a lab-measured personal maximum.
- Moderate intensity is shown as roughly 50% to 70% of estimated max, and vigorous as about 70% to 85%.
- Medication, heart conditions, and fitness level can change what is appropriate for you.
Why this page matters
Heart-rate zone pages help people translate exercise advice into numbers they can actually use on a treadmill, bike, or watch during training.
This version uses the common age-based maximum-heart-rate estimate, which is simple and practical but still only an approximation.
Frequently asked questions
Why is target heart rate shown as a range instead of one number?
Because exercise intensity is usually guided by a target zone, not a single exact beat-per-minute value.
Does this replace exercise advice from my doctor?
No. It is a general fitness estimate and does not replace individualized medical guidance.
Can fit athletes have different real max heart rates?
Yes. The formula is only a population estimate, so an individual's actual maximum may be higher or lower.
