Two-arm randomized controlled trial will recruit patients with unresectable pancreatic cancer undergoing chemotherapy. Participants will be randomized (1:1) to an Intervention Group (resistance training twice weekly) or a Control Group (standard care). The primary outcome is the change in total lean body mass (assessed by DXA) at week 12. Secondary outcomes include maximal strength, peak power, cardiorespiratory capacity, and patient-reported measures.
