It is important to be in the right heart rate zone if you want to burn calories or train your heart. Often people are not achieving their desired results and work themselves too hard and it is because they do not realize this.

Reaching the correct heart rate can help in gaining the most benefits from working out.

While at the gym, running, walking or biking heart rate monitors will tell you what your heart rate is precisely, this allows you to keep your heart rate exactly at the intensity you want it, meaning that you can achieve the best possible gains from the time you spend exercising.
