“Your heart is a very special muscle. Your heart does not move any bones. Your heart’s job is to pump blood. Blood brings food and oxygen to every cells in your body. Moving all that blood is a big job. You have trillions of cells. To get all these cells what they need, your heart must beat abouteighty times every minute. It even beats when you are asleep. Open and close your hand eighty times quickly. Does it make your hand muscles tired? Can you imagine doing this every minute of every day? Your heart does it. Your heart is the hardest working muscle in your body!
Exercise can save your heart more than a half a million beats each year! When your heart gets stronger, it pumps more blood with each beat. This makes your heart healthier.”
