Exercise and Asthma in Obese Adults

The primary aim of this pilot study is to recruit and retain obese adults with mild-moderate persistent asthma for a study protocol that includes exercise at a moderate intensity level in a home-based setting. The investigators primary hypothesis is that compared to no intervention, 12-weeks of moderate intensity aerobic exercise will attenuate serum levels of adipokines (leptin, adiponectin), and other pro-inflammatory markers. The investigators will also analyze the effect of the intervention on fitness levels, pulmonary function, asthma symptoms, asthma control, and asthma-related quality of life. Given that this is a proof of concept/feasibility study, there is no primary outcome measure. The following measures will be assessed: * Obesity related biomarkers and other markers of inflammatory responses: * Asthma symptoms and asthma control measures: * Lung function * Fitness levels and physical activity levels:
