Wear the product slightly more tightly around your wrist
while working out to maximise the precision of the heart
rate measurement.
Many exercises such as cycling or weightlifting require
you to angle your wrists. This may interfere with the heart
rate measurement if the product is worn too low on the
wrist. For the best results, wear the product for a few
minutes before you begin your workout.
If your hands or skin feels cool quickly, warm up your skin
below the sensor. Do some warm up exercises before you
begin your workout.
During very intense workouts or other activities, which
cause forceful or arrhythmic movements of your wrist,
the sensor may not be able to measure your heart rate
correctly.
