Preoperative Prehabilitation for Sarcopenic Patients Prior to Pancreatic Surgery for Cancer

This study is testing a "prehabilitation" program — a structured exercise plan before surgery — in patients with sarcopenia (low muscle mass and strength) who are scheduled to have major pancreatic cancer surgery. Low muscle mass before surgery is associated with worse outcomes, and this study aims to improve that. **You may be eligible if:** - You are scheduled for pancreaticoduodenectomy (a major surgery to remove part of the pancreas) for pancreatic cancer - You have been identified as sarcopenic (having low muscle mass/strength based on standard assessments) **You may NOT be eligible if:** - You are under 18 years old - You have cardiovascular disease or significant vascular disease that makes exercise unsafe - You are physically unable to exercise - Your surgery is an emergency Talk to your doctor to see if this trial is right for you.
