Boxing Behing Bars is a cooperation between 3 organizations. After taking different, conscious steps, we started with the implementation. We intended to form two different groups, one for sportive prisoners and one for prisoners with a low self-esteem. The reality showed we mostly reached only sportive inmates. The trainings were given by a famous Belgian boxer, Junior Bauwens, and a prison guard who’s also involved in the boxing sport. We also worked with a code of conduct. To make them conscious about the seriousness of this project and also to show to prison staff we put some conditions for the participants. After a positive evolution of the project in 2022, we looked for and found again resources to repeat the project in 2023.
