Heart Rate

The heart Rate, sometime called a pulse, is simply the number of times your heart beats every minute. One measurement of a person's fitness is his resting heart rate how hard his heart has to work while the person is sitting.Resting heart rates vary from 60 to 90 beats per minute. Physically fit people and people with good genes have a lower resting heart rate.Less fit people, people on some medications, people dealing with stress, and people who have just come from the coffee shop may have higher resting heart rates. (Caffeine tends to increase resting heart rate.)
