Inclusion Criteria: 1. Age ≥50 years 2. A history of hematological malignancy 3. Participants must be able to and willingly give informed consent Exclusion Criteria: 1. Patients receiving intensive induction or consolidation chemotherapy. Maintenance chemotherapy, or lower-intensity chemotherapy for an indolent hematological malignancy is allowed. 2. Neurodegenerative disease (e.g. Alzheimer's dementia), stroke, or uncontrolled psychotic disorders (e.g. schizophrenia or bipolar disorder) in the past 3 months if those disorders are considered significant enough to impair participation in the study. 3. Illnesses such as clinical evidence of decompensated heart failure, unstable angina, or orthopedic or neuromuscular disorders that could limit safe participation in aerobic exercise. 4. Cardiopulmonary exercise test results that preclude safe exercise (e.g., life-threatening arrhythmia, balance difficulties, peak VO2 \<10 ml/kg/min). 5. Estimated life expectancy of less than 6 months (that precludes assessment of study primary endpoint). 6. Participants who do not plan to follow up at the participating center.
