Exercise

Exercise is any action that gets you moving. You can run, bike, swim, jump rope, or row a boat. It’s all good for you!
There are three kinds of exercise. One is stretching. You may do this in dance, yoga, or at the gym. When you stretch, you keep your muscles bendable.
Aerobic exercise 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!
