DescriptionObesity is disproportionately prevalent among limited-resource audiences, like participants of the New Jersey Supplemental Nutrition Assistance Program Education (SNAP-Ed). Physical activity is an integral component for weight management, but barriers like time constraints and a lack of space and expensive equipment often prevent this target audience from meeting national physical activity recommendations. Aerobic exercise DVDs may help ameliorate these barriers; thus, this investigation's purpose was to assess their viability for use with SNAP-Ed participants both in the classroom and at home. Five nutrition educators evaluated 124 DVDs to assess their: cast members' demographics; levels of intensity and complexity; adherence to safety guidelines and exercise recommendations; and space and equipment needs. The results of this study supported the notion that exercise DVDs may help the target audience overcome physical activity barriers in that 70 (56%) of the DVDs required no equipment, and the space requirements of all of the videos were modest. Existing DVDs may, however, be of questionable appeal for use with SNAP-Ed participants due to a lack of racial diversity, i.e., the majority of the cast members were White, thin, adult women. Several types of DVDs, particularly "Tae Bo" and kickboxing, would likely have limited appeal for this population due to their high levels of intensity. Similarly, several types of DVDs would likely be unsuitable with regard to complexity, with belly dancing and dance aerobics workouts being rated as the most complex. Walking DVDs may be the best option for nutrition educators to recommend. They were characterized by both low intensity and complexity, yet elicited an average percent maximum heart rate for the research team of 69.88+7.37, which was consistent with national guidelines for moderate to vigorous activity. However, future research endeavors are needed to assess their feasibility with this audience.
