Leg warmers at the ready! In 1982, an exercise video starring actress Jane Fonda was released and changed the world of health and fitness forever. It was the first non-theatrical home video to top the sales charts, and became the top-selling VHS tape for six years, selling a total of 17 million copies. Opening up the once male-dominated fitness industry to women, her ballet-style leg warmers and encouraging shouts of “feel the burn” and “no pain, no gain” left a lasting legacy.
