ZONE 2 / YOUR TAKEAWAY

Understand the idea

No watch

First check

Find the method or definition used by your guide. If none is given, mark it as unknown.

Keep separate

Keep the device label and your description of effort separate; neither measures a personal threshold here.

Next inspection

Compare the definitions before comparing the numbers. Save the source you used.

Device note

No device is needed to read the explanation. This guide does not set a heart-rate target.

Educational draft, not medical advice or a training prescription. This guide does not interpret symptoms or measure your exercise thresholds. Seek qualified advice for symptoms, conditions or medication-related questions.
