Wear Heart Rate Sensor

Use our heart rate sensors when training to get the most out of Polar’s unique Smart Coaching features. Heart rate data gives you an insight into your physical condition and how your body responds to training. This will help you run at the right intensity and improve your fitness.

Although there are many subjective clues as to how your body is doing during exercise (perceived exertion, breathing rate, physical sensations), none is as reliable as measuring heart rate. It is objective and is affected by both internal and external factors - meaning you will have a dependable measure of your physical state.

  1. Moisten the electrode areas of the strap.
  2. Attach the connector to the strap.
  3. Adjust the strap length to fit tightly but comfortably. Tie the strap around your chest, just below the chest muscles, and attach the hook to the other end of the strap.
  4. Check that the moist electrode areas are firmly against your skin and that the Polar logo of the connector is in a central and upright position.

Detach the connector from the strap, and rinse the strap under running water after every training session. Sweat and moisture may keep the heart rate sensor activated, so also remember to wipe it dry.
