The more intensively you exercise, the faster your heart beats, and the more your BPM increases.

Each level of intensity has a different effect on your body: comfortable exercise, weight loss, better endurance etc. HEART RATE ON THE WRIST: PHILIPS TECHNOLOGY The heart rate measurement on the wrist is a huge technological advance making heart rate watches simpler and more comfortable. For more than two years now, our Research amp; Development teams have been testing different options for measuring heart rate on the wrist. We have chosen to use the latest Philips optical heart rate technology so we could offer one of the most reliable sensors on the market.
