When going through training or exercise, it is important to keep an eye on your heart rate. By using a heart rate monitor you can ascertain an exercise level that will optimize the burning of fat and you will improve your metabolism. A heart rate monitor will observe the rate of your heart and provide feedback. Heart rate should be kept at certain intensity. If your heart rate gets too high your activity can become counterproductive, if it is too low you are not getting any substantial health benefits.

A heart rate monitor is a personal device that will do this for you. It will measure heart rate in real time and keep a record for later study. The device should be kept in good order to keep it running accurately. The transmitter and wrist display are water resistant but they should be stored in a dry place when not in use. The transmitter can be cleaned with warm soapy water and dried with a soft cloth after each use. Remember that it is powered by batteries that will have to be replaced from time to time.
