A normal heart rate is between 60-100 beats per minute at rest (sitting, relaxing, etc.). It is well-known that the average resting heart rate for well-trained athletes is 40-60 beats per minute! However, this rate can change dramatically while sleeping or with daily activity and exercise.
Resting Heart Rate. The experts at the Mayo Clinic suggest the normal resting heart rate for an adult is between 60 and 100 beats per minute. If you are a healthy adult, the lower your resting heart rate is the better. If you are a trained athlete, your resting heart rate may be 40 beats per minute. However, this is normal because your heart is able to pump blood through your body more efficiently. To make an accurate determination of your heart rate, take your pulse when you are sitting down at rest, not moving or walking.
