A healthy person should see his heart rate decline by 15 to 20 beats per minute in the first minute after stopping exercise. Your recovery heart rate--the pulse you register two minutes after you stop exercising--is a measure of how fit you are. Say you run for 30 minutes at an average heart rate of 155 beats per minute and your heart rate two minutes after finishing is 95 beats per minute. As you become more fit, your heart rate will decrease faster after that 30-minute run, and your recovery heart rate will be lower at the two-minute mark.
