Prehabilitation programs essentially based on physical activity improvement may reduce postoperative complications after major surgery. We hypothesize that a multimodal program based on physical activity, nutritional support and mental preparation may not only improve postoperative recovery and reduce costs but also improve health status beyond postoperative period.~Non-randomized monocentric open cohort study vs historical comparative group testing the efficacy of a multimodal prehabilitation program for unfit patients based on nutrition, physical activity and mental preparation in reducing postoperative complications in elective major surgery.~Other outcomes will be measured : length of hospital stay, hospital readmissions, direct costs, health status at 1 and 6 months.~Moreover, the feasibility and adherence of Paprika program will be evaluated. Inter-data centres relating to the implementation of the same prehabilitation program will be compared with the consortium Paprika (Hospital Clinic of Barcelona, University of Cologne, University of Gdansk)
