The goal of this pilot clinical trial is to compare telehealth and onsite supervised maintenance exercise program for adults with Chronic Lung Disease. The specific aims of the study are: * To compare 8-week supervised maintenance program delivered onsite and via tele-rehab with no maintenance for patients with Chronic Lung Disease following discharge from traditional exercise or physical therapy or onsite outpatient rehabilitation programs on clinical outcomes (dyspnea, exercise capacity, physical function, physical activity, and quality of life) at 8 weeks and 4-months post-intervention. * To compare the differences in dyspnea, exercise capacity, physical function, physical activity, and quality of life between an 8-week maintenance program delivered onsite and via tele-rehab at 8-weeks and 4-months post-intervention in patients with Chronic Lung Disease following discharge from traditional onsite outpatient rehabilitation. Participants in both intervention groups (onsite and tele-rehab) will undergo a baseline onsite assessment followed by an 8-week supervised exercise intervention either onsite or in a telehealth setting. Control group will receive biweekly check in calls, but no active intervention.
Inclusion Criteria: * All adult patients 40 years and older with physician diagnosed Chronic Lung Disease within 2 months of discharge following completion of a traditional onsite outpatient rehabilitation or physical therapy or exercise program for their condition * Able to walk independently with or without mobility devices * Able to complete a six-minute walk test at discharge with or without supplemental oxygen maintaining an oxygen saturation at or above 85% * Able to follow commands and instructions in the English language * Have ability to connect to the internet Exclusion Criteria: * • Those with significant mobility limitations such as those with a history of stroke, neurological comorbidities such as Parkinson's disease or relapsing multiple sclerosis, or significant degenerative osteoarthritis, or any other joint impairments that compromise ability to walk independently with or without an assistive device. * Patients who primarily rely on a wheelchair for mobility * Patients with or without supplemental oxygen who are unable to complete a walking test without a drop in oxygen saturation to below 85% at discharge from traditional outpatient rehabilitation * Patients with baseline hemodynamic compromise, unstable angina, a recent myocardial infarction within a week, uncontrollable atrial fibrillation not managed with medications, advanced stage heart failure (New York Heart Association class 4), or those with mechanical circulatory assist devices for the heart such a ventricular assist device (VADs) * Inability to communicate in the English language
