In 2004 De Rode Antraciet (DRA) published the book ‘Fitness between walls’, especially tailored for prisoners. The Red Anthraciet ensures that prisoners who stay in Flemish prisons can participate in sports and cultural activities. More than ten years later, DRA wants to use the project ‘Fit @ Cell to promote sports and exercise in the cell again. Fit @ Cell is a DVD that allows prisoners to put together their own workout. The DVD includes several warm ups, upper body exercises, lower body exercises, cool downs and sporting tips. The detainee can choose his/her own level (beginner – advanced – expert) and then composes his/her own training.
