When you measure your heart rate while exercising and analyze it afterwards, you can make your sporting performances even better! Improve your endurance or adjust the intensity of your training. This can be done with a heart rate monitor. These come in the form of a heart rate belt for your chest or a built-in heart rate monitor in a sports watch. You then read the data in an app or on your computer. Do you want to know your pulse during exercise? Then connect the heart rate belt via Bluetooth or ANT + with a sports watch or your fitness equipment.
