All patients will receive prehabilitation preoperatively for 4 weeks, that is composed of 3 elements, exercise, nutritional supplements and psychological coping strategies. Both exercise protocol will be supervised, 3-time per week, in-hospital programs. Patients will be randomized to perform either HIT or MC training. Exercise intensity will be defined and personalized on the individual values at cardiopulmonary exercise testing (CPET). Patients' nutritional status and dietary intake will be assessed by the nutritionist, and supplement will be prescribed if needed to achieve a daily intake of 1.5 g protein/kg. Perioperative care will follow the McGill Surgical Recovery Pathway, also called Enhanced Recovery Program, which is an evidence-based care plan set up by the Surgical Recovery (SuRe) multidisciplinary committee of the McGill University Health Centre.
