My name is _________ from the Minnesota Institute of Public Health. I am working with the MN Departments of Human Services, Health, Education and Public Safety, in an effort to understand the needs of prevention professionals throughout the state.
People who are 30 years old and have an exercise heart rate of 138 heartbeats per minute, the average good rate for someone their age, have a good post-exercise heart rate when itâs 98 to 108 heartbeats per minute one minute after exercise.
Target Heart Rate Your heart rate is one of the easiest measurements to take to determine your level of exertion during exercise. The American Heart Association recommends working in a safe target heart-rate zone between 50 and 85 percent of your maximum heart rate. An 18-year-old boy can find his maximum heart rate by subtracting his age from 220. This would put his maximum heart rate at 202 beats per minute, meaning he should exercise between 101 and 172 beats per minute. An 18-year-old girl can subtract 88 percent of her age from 206, putting her maximum heart rate at 190 beats per minute and her target heart-rate zone between 95 and 162 beats per minute.
