Do you like doing exercise? Do you want to know the benefits from the exercise? Let's learn something about exercise.
Exercise is any action that gets you moving. You can run, ride a bike, swim, jump rope or row a boat. It's all good for you!
There are three kinds of exercise. One is stretching(拉伸). You may do this in dance, yoga or at the gym. When you stretch, you keep your muscles(肌肉)bendable(可弯曲的).
Aerobic exercise(有氧运动)makes your heart beat fast. You get this kind of exercise when you walk or run. Your heart beats fast when you swim, too.
The last kind of exercise makes your muscles strong. You build strong muscles when you lift weights. When you sprint or run fast, you make your muscles strong, too.
You get exercise when you play tag and hide and seek. Leapfrog and ball games are also good to do. So go outside and have fun! If you keep on doing exercise, you will know the more exercise you do, the healthier and happier you will be.
