Want Mad Men Curves? Skip the Gym

"Mad Men" is known as much for its curvy actresses as its complicated plotlines and advertising jargon. When the hit AMC show first aired, the world welcomed voluptuous stars like Christina Hendricks and January Jones who brought curves back to the small screen.

Jones recently revealed what it takes to be a "Mad Men" woman: healthy eating and minimal gym time.

In an interview with Tatler, Jones -- who plays troubled housewife Betty Draper-Francis -- revealed that the show's creator, Matthew Weiner, advises them to stay away from the gym. "He would prefer we didn't work out and that we eat really well, so we look like healthy women," she said, according to reports from the UK's Daily Mail.

But this isn't really news -- last year, she said something similar to OK Magazine: "they tell us to gain weight, gain weight, gain weight, because they want a soft, voluptuous woman which they were [back then] which is beautiful, as it should be."

It makes sense, really. After all, most 1950s housewives didn't have arms like Madonna.

But don't take this as a cue to ditch your gym membership just yet -- it's not like the "Mad Men" ladies are brownie-scarfing couch potatoes. Last September, Hendricks dished to Self Magazine about loving both fresh veggies and her regular workouts with her husband. And Elisabeth Moss admitted to People that she wears padding on her size four frame to fit into Peggy Olson's size six costumes.

One thing is clear: These women love their curves: "It's OK to have curves and be a woman. I wish more women would realize that's what men like," Jones said. As for Hendricks? "My healthiest habit is keeping positive about my body at whatever stage it is -- being confident and celebrating who I am at the moment."

Jones also admitted that she had to give credit to another major influence in Betty's classic hourglass physique: The girdle. "It gives you such a nice shape," she said.

Sure, girdles might hold in your midsection, but they won't help you slim down.
