A We could say that our muscles are one of the largest organ systems in the human body. They are made up of protein fibres. Anyone who eats meat knows exactly what muscles are, because they are the part of the animal that we eat when we eat a steak or a lamb chop. Muscles are also one of the things that make the models and athletes we see in magazines look good.

B However, muscles are important for more than appearance and food. The main job of muscles is to help us get around. They work in pairs and move our bones by relaxing, or getting longer, and contracting, or getting shorter. Without muscles, we could not move at all. Still, muscles are good for a lot of other things, too.

C Did you know that most of the energy we use every day is used up when we are not even moving? In fact, around seventy percent of the calories our bodies need are used when we are sitting still. Every tissue in our bodies needs energy just to exist, but muscle needs more energy than the other tissues, so the more muscle people have, the more energy they burn while they are doing nothing.

D This is why it's important for people to exercise. Just a few kilos of muscle will burn calories every day and these calories add up. For example, if a person gains 10 kg of muscle, which is not a lot, he or she will use up an extra 100 calories a day just by doing nothing. And not using 100 extra calories a day adds up to 4.7 kg more fat every year: enough to cause obesity.

E On top of this, muscle has a large role in how the body uses sugar. Muscles take sugar from the blood and use it to make energy to move the body. Athletes know this; so they often eat bananas or other carbohydrates before they work out. And muscles that are used to working hard do a much better job taking sugar from the blood all the time. This is why people who do not exercise are more likely to develop diabetes.

F Muscles are also the largest store of protein in the body. When people are sick or injured, they need far more protein than usual to get well. Sometimes, they need more protein than they can eat; in this case the body uses the protein in the muscles to heal the injury. Researchers have shown that accident and burn victims, and even cancer patients, who have more muscles to begin with are more likely to survive.

G Finally, measuring the amount of muscle elderly people have helps doctors to predict how long they will live. If they exercise, older people can successfully stop muscle loss, but it is very difficult for them to build new muscle. It is essential for young and middle-aged adults to build muscle before they are old, and to continue exercising throughout their whole lives. So, don't put it off; start exercising now!
