Placement for all-day wear vs exercise:
When you're not exercising, wear device a finger's width above
your wrist bone.
For optimized heart-rate tracking while exercising:
·
Try wearing Device higher on your wrist during exercise for an improved
fit and more accurate heart-rate reading.
Wear Hyper X
Make sure the tracker is in contact with your skin.
Don't wear your tracker too tight, a tight wristband restricts blood flow,
potentially affecting the heart-rate signal. The tracker should be
slightly tighter (snug but not constricting) during exercise. With
high-intensity interval training or other activities where your wrist
is moving vigorously and non-rhythmically, the movement may
limit the sensor's ability to provide a heart-rate reading. If your tracker
doesn't show a heart-rate reading, try relaxing your wrist and staying
still briefly.
