Using heart rate monitors are a great way to monitor your fitness level. Your heart rate is very important for determining the health of your body and your well being. This is especially true when you are participating in some strenuous exercises. As you exercise or participate in a sports activity, nearly your entire muscle mass is under strain.

The following points are ways in which your exercise program can benefit from the use of a heart rate monitor.
