This chapter synthesises the monograph’s autobiographical, qualitative, and survey strands to draw out practical implications and future directions for supporting military veterans living with post-traumatic stress disorder (PTSD). It first situates PTSD within contemporary diagnostic and treatment landscapes, noting high prevalence in UK veterans, heterogeneity of presentation, and persistent challenges with access, adherence, and durability of benefit in orthodox care. It then considers the expanding, but uneven, evidence for complementary approaches. A central through-line is the role of physical exercise as an adjunct to psychological and pharmacological treatment, with modes including aerobic, resistance, flexibility, and functional training. Across the monograph, exercise is associated with reduced arousal and mood disturbance, improved sleep and agency, and enhanced social connection, while acknowledging barriers such as triggers, stigma, disability, and variable response. Using Self-Determination Theory as an interpretive lens, the chapter argues for needs-supportive delivery that cultivates autonomy, competence, and relatedness in trauma-informed environments. Policy and practice recommendations include embedding structured exercise within NHS and veteran-sector pathways, developing joint clinician–coach models, improving signposting, investing in workforce training, and commissioning longitudinal trials. A proposal is outlined for a rolling 12-week CrossFit® intervention with mixed-methods evaluation to strengthen the evidence base and inform scalable implementation. Limitations of the current work are acknowledged, including small samples and design constraints, alongside the researcher’s positionality. The chapter closes by positioning exercise not as a replacement for orthodox therapies, but as a credible, person-centred complement that can help veterans reclaim control, connection, and hope.
