Have you tried to run or walk for exercise and then given up？If your answer is yes，you should try a new kind of exercise：aquatic （水中的） exercise.Aquatic exercise is like exercise on land，but you do it in a swimming pool.More and more people are trying aquatic exercise.
   Aquatic exercise feels easier than exercising on land.Why？You weigh about 90% less in the pool!It is better for your knees than running or walking.Water is about 1，000 times thicker and heavier than air.To move through the water，your body has to work four times as hard.As a result，you can burn more calories（卡路里）.
   In fact，most people say they feel more relaxed in the water.They stop thinking about the things that make them worried.They feel in control of their bodies.The cool，quiet environment makes them feel good.
   But what if you are afraid of water？No problem!There is nothing to worry about.Aquatic exercise is not dangerous or hard to learn.It doesn't require any special skills.You don't even need to know how to swim.Aquatic exercise is for everyone.
