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.
