In the Swimming Pool One day. Tommy and his brother Alex went swimming. As they got close to the swimming pool, they saw something strange—a man was jogging in the water. The two brothers were very curious. Tommy asked the man, " Why are you jogging in the water, not on land?" The old man smiled and said, " Well, that is simple. Running in water uses the same muscles as running on land. But it is much easier on my knee joints. "
“ Why do you prefer jogging to swimming?” asked Tommy. “ Jogging is slower than swimming, but it is more tiring. It is also more difficult to keep your balance while jogging in water. And it's just as good for the heart, lungs and muscles. ” The two kids happily jumped in the water. They learned that jogging in water is a fun way to get fit!
