Don't stress
With the ECG (electrocardiogram) you can use your GPS watch to measure the variation in your heart rate directly from your wrist. This is important data for measuring your body's response to stress and its ability to recover. The COROS system converts all this data into simple, comparable data from athlete to athlete.
