The heart normally beats about 60 to 80 times every minute when a person is at rest. This is called the heart rate. In some people, the heart rate may be even less than 60 beats per minute (bpm), and this is perfectly safe as long as they feel well, have normal blood pressure and their heart speeds up with exercise. Olympic athletes commonly have heart rates of 30 to 40 bpm.
For adults 18 and older, a normal resting heart rate is between 60 and 100 beats per minute (bpm), depending on the personâs physical condition and age. For children ages 6 to 15, the normal resting heart rate is between 70 and 100 bpm, according to the AHA. But a heart rate lower than 60 doesnât necessarily mean you have a medical problem. Active people often have lower heart rates because their heart muscles don't need to work as hard to maintain a steady beat. Athletes and people who are very fit can have resting heat rate of 40 bpm.
