16. SUZANNE SOMERS
Fitness videos: Thighmaster: Tonerobics (1992), Suzanne Somers' Toning System Workout Video: 12 Great Upper & Lower Body Exercises (1992)
Do we even need to explain? When it comes to workout tapes, Somers might be even more iconic than Jane Fonda—and that’s saying something.
She has two big contributions that can’t be denied. One: She put the Thighmaster on the map. Seriously, people still buy that shit today. Two: She was responsible for giving '80s babies their first stiffy whenever her commercials ran during The Price Is Right.
