Hodgkin lymphoma survivors face elevated risks of cardiovascular disease and premature aging. HIIT, which alternates high-intensity effort with recovery periods, has shown benefits in adult cancer survivors but has not been tested in younger populations. This study will assess whether recently treated survivors can complete a remotely supervised 12-week HIIT program and evaluate its effects on multiple health outcomes. Participants will undergo baseline and post-intervention assessments including exercise testing, body composition, autonomic function, and blood biomarkers. The intervention is delivered via a secure web-based platform with live supervision by exercise physiologists.
