The All-Nude Workout Video (1992) was the first in a series of naked exercise videos produced by Majorvision International and fitness expert Brian Sterling . Filmed mainly on location at the Bodyshaper's Gymnasium in Manchester, leading the workout in the original was international model and fitness instructor , Marie-Ann De Kosta . Her training team consisted of naturist couple, Susan and David Martin, and male model Rick. Narrated by David Roth , the video was segmented to include both nude aerobic exercises and naked weightlifting activities, complemented by general training and nutritional advice. Aimed primarily at the naturist market, the inclusion of both male and female models also afforded the product a commercial value in high street outlets. The success of the initial offering spawned a series of sequels throughout the 1990s.
