For optimized heart rate tracking, keep these tips in
mind:
1. Experiment with wearing the watch higher on your
wrist during exercise. Because the blood flow in your
arm increases the farther up you go, moving the
watch up a couple of inches can improve the heart
rate signal. Also, many exercises such as bike riding
or weightlifting require you to bend your wrist
frequently, which is more likely to interfere with the
heart rate signal if the watch is lower on your wrist.
2. Do not wear your watch too tight. A tight band
restricts blood flow, potentially affecting the heart rate
signal. The watch should also be slightly tighter (snug
but not constricting) during exercise than during
all-day wear.
