The easiest way to do this is to use a generic formula meant for the average person. For men, your maximum heart rate can be estimated by subtracting your age in years from 220. For example, a 20-year-old man would have a maximum heart rate of 200 beats per minute. For women, a newer standard is to take 88 percent of your age and subtract it from 206. Beats Per Minute in Exercise. The speed of your heart rate depends on the intensity of exercise that you wish to work at. The American Heart Association recommends exercising somewhere between 50 to 85 percent of your maximum. Beginners should start at the low end of this range and work up as fitness levels improve.
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.
