Three ways to set your zones
Automatic
The app uses your age, maximum heart rate, and average resting heart rate. Heart Rate Reserve can adjust the zones when those values change.
Semi-automatic
Use calculated ranges as a starting point while keeping control of selected inputs.
Manual
Enter the boundaries you already use from a coach, lab assessment, or another training system.
The five-zone model
- Zone 1: below the moderate training range
- Zone 2: typically 60–70% of maximum heart rate
- Zone 3: typically 70–80%
- Zone 4: typically 80–90%
- Zone 5: typically 90–100%
Heart rate percentages are general training categories, not medical advice. Individual zones vary, and users can adjust the app’s boundaries when needed.
