Impact of Prehabilitation in Oncology Via Exercise- Esophageal (IMPROVE-Esophageal)

The goal of this study is to (1) determine the feasibility of a prehabilitation exercise program (exercise before a medical treatment) in adults with esophageal cancer before surgery (esophagectomy). The pre-surgery exercise program will include resistance and aerobic training during the weeks before surgery. We will also assess pre-surgical care needs in adults with esophageal cancer. Researchers will compare the exercise intervention to usual care- which is standard medical care and post-surgery surveillance/follow-up to understand the impact of exercise before surgery. We will follow-up with participants before surgery, and after surgery at 2 weeks, 6 weeks, and 4-months at appointments that coincide with clinical follow-ups. The main questions of this trials are: * Is exercise before surgery for esophageal cancer feasible and acceptable to patients? * How does exercise before surgery change physical function and psychosocial health? * What are important pre-surgical needs for adults with esophageal cancer?
