average resting heart rate for an adult
For adults 18 and older, a normal resting heart rate is between 60 and 100 beats per minute (bpm), depending on the personâs 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 doesnât 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.
