Do not change a value just to make a chart look better.
Your maximum heart rate setting may be estimated or based on recorded data. Check where it came from before changing it. An age formula is a starting estimate, not a personal measurement.
Check the setting, not just the label
Read the heart rate and zone guidance for your watch. Check whether each sport uses maximum heart rate, heart rate reserve (the gap between resting and maximum heart rate), or a threshold value from a test or estimate. Different methods mean different boundaries.
What is worth reviewing?
- The heart rate value used to set the zones, and its date.
- Whether automatic updates are enabled.
- Separate running and cycling settings.
- Unusual spikes or gaps in the recorded heart rate.
Avoid a quick fix that creates a new problem
Do not raise the value just to move a run into a preferred zone. Do not assume one high reading is a valid maximum. Ask a qualified coach or tester if you need help understanding recorded values.
You do not need an all-out test to start
You can use the app and learn from sessions without testing your maximum. Hard exercise tests need suitable guidance, particularly if you have health concerns.
