Exercise is one of the most important pillars of happiness and wellbeing. The Finnish national organisation for youth exercise Nuori Suomi asked Demos Helsinki to reflect on the kind of society where children and youngsters experience more of the enjoyment and utility that exercise brings. A new direction for youth exercise was developed through an open process together with hundreds of different actors, ranging from traditional exercise and sport experts to new actors and procedures. The results of the project were used to compile a manifesto for children and youth exercise.
