This study is looking at how different amounts of structured treadmill walking (90, 150, or 300 minutes per week) can help reduce side effects from treatment for gastrointestinal (GI) cancers. Researchers want to find out which amount of exercise is practical, safe, and has positive effects on your body. They will also see if exercise changes how well you can stick to your cancer treatment plan, including whether you need to stop, delay, or reduce your treatment, or take extra medicine for side effects. You may be able to join if you are 18 or older, have colorectal or esophago/gastric solid tumors, and are about to start chemotherapy. The study aims to see if participants can receive at least 90% of their planned treatment dose, measured over 5 years.
