Inclusion Criteria: 1. Age ≥18 years. 2. Scheduled to receive ipilumab and nivolumab as first line of immune checkpoint inhibitor therapy for Renal Cell Carcinoma (RCC). a. Patient may receive the first infusion of ipilimumab/nivolumab prior to eligibility determination 3. Subjects with brain metastases are allowed if they are asymptomatic, without edema, and not on greater than or equal to 10mg daily dose of systemic corticosteroids or receiving radiation therapy for at least 14 days prior to beginning protocol therapy. 4. Karnofsky Performance Status (KPS) of at least 70% 5. Able to walk on a treadmill per patient report. 6. Ability to understand English and the willingness to sign a written informed consent document. Exclusion Criteria: 1. Major surgery (e.g. nephrectomy) less than 28 days prior to the first dose of ipilimumab/nivolumab. 2. History of cerebrovascular accident including transient ischemic attack (TIA) within the past 6 months. 3. Osseous metastatic disease with unacceptable risk of impending fracture due to study assessments, in the opinion of the investigator. Note: This criterion must be met prior to CPET. 4. Absolute contraindications to cardiopulmonary exercise testing and/or aerobic training, as determined by the attending oncologist: * Uncontrolled arrhythmia causing symptoms or hemodynamic compromise * Recurrent syncope * Active endocarditis * Acute myocarditis or pericarditis * Symptomatic severe aortic stenosis * Uncontrolled heart failure * Acute (within 3 months) pulmonary embolus or pulmonary infarction * Thrombosis of lower extremities * Suspected dissecting aneurysm * Uncontrolled asthma * Pulmonary edema * Room air desaturation at rest \<85% * Respiratory failure * Acute non-cardiopulmonary disorders that may affect exercise performance or be aggravated by exercise (i.e., infection, renal failure, thyrotoxicosis) * Mental impairment leading to inability to cooperate. * Poorly controlled hypertension \[defined as systolic blood pressure (SBP) of \>150 mmHg or diastolic blood pressure (DBP) of \>90 mmHg\].
