Demonstrate the size and location of your heart by making a fist. Hold your fist in the center of your chest. Your heart beats day in and day out without your thinking about it. At rest, an adult's heart squeezes about 70 times in one minute. A child's heart squeezes about 95 times per minute.
Exercise causes the heart to work even harder and squeeze even more times per minute.
