Your resting heart rate is an indicator of your fitness level because it directly determines how hard your heart is working at rest and during certain aerobic exercises. The human body's heart can only beat at a maximum of 220 beats per minute but this varies through age. Knowing one's maximum and resting heart could help you in determining the appropriate aerobic exercises that you can engage in.
