Sport-based prison interventions may particularly benefit women, a vulnerable population within the penal system. However, evidence of their impact is mainly based on men's experiences. This study qualitatively examines the experiences of 11 women enrolled on the Twinning Project, a football-based prison programme designed to reduce recidivism and enhance employability. Thematic analysis of semi-structured interviews revealed positive outcomes for participants, such as improved self-perceptions and intentions to help others. However, the prospective long-term impact of vocational qualifications was less evident. Barriers to engagement were identified in parts of the programme's structure and delivery, women's health issues, and participants' perceived lack of control over post-release outcomes. Enablers included support from peers and staff, the appeal of football itself, and the absence of criminal identities. The findings highlight the Twinning Project's potential to benefit women prisoners and underscore the need for sports programs to accommodate gender-specific experiences in prison.
