(2019安徽B篇)Have you tried to run or walk for exercise and then given up? If you answered 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.
