For optimized heart rate tracking keep these tips in mind:
•! Experiment with wearing the tracker higher on your wrist during exercise.
Because blood flow in your arm increases the farther up you go, moving the
tracker up a couple inches can improve the heart rate signal. Also, many
exercises such as bike riding or weight lifting cause you to bend your wrist
frequently, which is more likely to interfere with the heart rate signal if the
tracker is lower on your wrist.
•! Do not wear your tracker too tight; a tight band restricts blood flow,
potentially affecting the heart rate signal. That being said, the tracker should
also be slightly tighter (snug but not constricting) during exercise than during
all-day wear.
•! With high-intensity interval training or other activities where your wrist is
moving vigorously and non-rhythmically, the movement may limit the sensor’s
