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.
Your pulse is a measure of how many times per minute your heart beats. You can find your pulse by lightly pressing on your skin anywhere there's a large artery, such as the side of your neck or the inside of your wrist just below your thumb. When you're resting your heart probably beats about 60 to 100 times per minute. When you exercise, your heart beats much faster, because it has to pump blood faster to supply your body's cells with the oxygen and nutrients they need to function during exercise. If you use an average of 80 beats per minute, your heart beats about 4,800 times per hour. That's a whopping 115,200 times per day. Over the course of a year, your heart would beat about 42,048,000 times! If you live to be 80 years old, your heart would have beaten approximately 3,363,840,000 times! That's over 3 billion heartbeats!
