The average heart rate for a teenager is around 80-110 beats a minute. <br /><br /><br /><br /> I hope I helped. Well it didn't because you are wrong. If you are a couch potato and never work out maybe 80-110 or if you just got done running. The average heart beat per minute is 60-80 beats per minute. <br /><br /><br /><br /> Well lets see I just got started learning about this in health and my health teacher said that the average heart rate for a teenager when at rest is about 72 beats per minute.
A healthy adult heart rate can range from 60 to 100 beats per minute during rest. Kids' heart rates can be as low as 60 beats per minute during sleep and as high as 220 beats per minute during strenuous physical activity. It's normal for athletic kids to have slower resting heart rates, often in the 40s or 50s.
