Swimming is my favorite sport! If you get children to love a sport (any sport), statistics show that they will be in better shape, have better grades, continue school, and learn that there is discipline for everything they do in life.
Besides the fact that it will help them develop great bodies.
Limit TV time for children and get them moving outside.
My suggestion is to let them watch television for games, soccer games, the Olympics to get them dreaming.
Get them thinking that they could be there and help them visualize that they can be the best in any sport they like!
