DIFFERENT TYPES OF EXERCISE A healthy body is one that is strong, flexible and can keep working over a long period. That's why it's important to do these three different types of exercise: 1 AEROBIC EXERCISE This kind of exercise makes you use more oxygen and it's great for your heart. When you do aerobic exercise frequently, you build stamina, so you can continue to do exercise for a long time. Your body doesn't get tired immediately, because your heart becomes very efficient at sending oxygen to your muscles. Some examples of aerobic exercise are swimming, basketball, cycling, and dancing. 2 EXERCISE TO BUILD YOUR STRENGTH When you do exercise, you want to make your heart strong, but also to make your muscles strong. This helps you to be active and full of energy. Strong muscles also protect your body. Running, cycling and skating are all good for strong legs, and some gymnastic exercises are great for strong arms and a strong stomach. 3 EXERCISE TO IMPROVE YOUR FLEXIBILITY Exercise can help to make you flexible. That means your muscles are strong but they can also move easily and in lots of different positions. You need good flexibility to do some sports like dancing or swimming, but also to play football or basketball. Gymnastics, yoga and martial arts can all help you to become flexible. 3 Now read the article on the right quickly and answer the questions. 1 What is the connection between this article and Celia's blog? 2 Who is the author of the text on the right? 3 What is the aim of this text? 4 How is the style of this text different from Celia's blog?
