In the 1980's Scott Madsen was the Soloflex boy, appearing in a series of iconic print ads, posters, brochures, and beautifully produced TV infomercials which mostly consisted of Scott wearing tiny gym shorts whilst demonstrating home work-out equipment. For gender balance, a young woman got in on the action a bit, but mostly it was Scott. I used to scan the cable dial (36 channels back in those days, and yes, it was still a dial) seeking out those ads, and most of the time I found them. After Scott left Soloflex he was replaced by a boy named Randy Potter. Randy was beautiful, but it just wasn't the same.
Here, as a special treat, is the very first Soloflex infomercial, entitled The Promise. To give you an idea of how times have changed, please note the narrator telling us that "you don't want big stomach muscles." Nowadays, huge abs seem to be the first goal.
