TRAINING WITH WRIST-BASED HEART RATE
HEART RATE TRAINING
Although there are many subjective clues as to how your body is doing during exercise (perceived exertion,
breathing rate, physical sensations), none of them are as reliable as measuring heart rate. It is objective and
affected by both internal and external factors—meaning that you will have a dependable measure of your
physical state.
MEASURING HEART RATE WITH YOUR M430
Your Polar M430 has a built-in heart rate sensor that measures heart rate from the wrist. Follow your heart
rate zones directly from your device, and get guidance for the training sessions you've planned in the Flow
app or web service.
