The human body is unique. Designed to function for a lifetime, it should be treated with respect. Too much strenuous exercise may be just as harmful as no exercise at all.

The body communicates in a language that is not always easy to understand. Polar has developed the OwnZone to help you better interpret the signals of your body. By measuring your individual heart rate limits, OwnZone guarantees a safe and effective exercise zone that guides you through your training program toward better results.
