Defining Normal Heart Rate. Your heart rate is simply the number of times your heart beats per minute. It can be determined by feeling your pulse on areas where the artery is close to the skin, such as your wrist or either side of your neck. An adult's normal resting heart rate (RHR) falls between 60 and 90 beats per minute. An athlete who is in great shape may have a RHR between 40 and 60.
