In the past children used to spend their leisure time after school and in summer holidays by playing football or riding their bike with their friends in the neighborhood. In current years, since the development of the Internet and advanced computer games, the parents are forced to adopt novel ways to make their children to get up, exercise and play with other children their age. A multitude of classes have been established in order to stimulate the needed high excitement of children: Pilates classes and yoga, triathlon and even classes in unicycle.
