Prison Body began as a research project in a former juvenile prison in Weimar, where artists and the general public were invited into the space to take part in fitness classes. Participants used only their bodies and the architecture of the prison to improve the physical form. Prisons are spaces that encourage physical improvement because they are characterized by two main circumstances that are also essential for success in fitness; time and discipline.

The project critiques the capitalization of spaces of significance once they become dysfunctional. It also challenges participants to question the role discipline in fitness regimes and how people are classified, disciplined and normalized by social processes that they have little direct control over.
