Heart rate

Single tap on the time screen to go to the heart
rate screen. This screen shows your heart rate
values and heart rate zones.
Current heart rate
Your current heart rate is shown in beats per
minute (bpm).
Heart rate zones
Heart rate zones span the range between your
resting heart rate and your maximum heart rate
and can help you identify the intensity of your
exercise. Your heart rate zone is shown in your
heart rate display with a heart icon and four dots.
- Heart rate zone 1
This zone mostly covers regular daily activities
such as leisurely strolls, moving around or
performing easy tasks within your house or
workplace.
- Heart rate zone 2
Activities that get your heart rate to zone 2
include brisk walking, hiking and leisurely biking.
During such moderate-intensity activities, your
breathing is often deep and you usually start to
sweat after ten minutes.
- Heart rate zone 3
Training in this zone helps you get fitter. It may
also help you control your weight.
- Heart rate zone 4
You will only be in this highest zone for brief
periods of time, as anaerobic exercise consists
of bursts of high-intensity activity such as
sprinting, interval training and heavy weight-
lifting.
Heart rate measurement
Heart rate is measured using our Opticardiogram
technology. This is a clinically validated sensing
technology, proven to be accurate for most people
under normal conditions.
Read section 'Wearing the health band' for more
information on how to get accurate measurements.
Note: When you experience problems with your
heart rate measurements, check if your problem is
mentioned in the troubleshooting chapter or call
