The benefits of water exercise and play have been well documented, and it's never too early to begin. This practical guide for children 4 and above contains games and activities for every skill level. All 101 games - from variations on classics like Follow the Leader to new ones like Message in a Bottle - are simple, easy to learn, and enjoyable for youngsters to play over and over again. Best of all, they burn calories and improve a child's overall fitness level. A special section covers exercises, including water walking and jumping and balance activities.
This is not a book. This is a long blog post. With lot of space on the page. And big graphics that take a lot of space. Which are quite rudimentary drawn.
The author seems to be 5 or about so as running on the side of a pool on wet hard surfaces is called fitness. And many games are prefixed with "this is a fun game" in a book in which the first word of the subtitle is fun.
