Donna Mills on how she stays in shape

“I do 100 sit-ups a day, 50 leg lifts, lots of stretching. I have a ballet barre in my little gym. And ride the bike for about 45 minutes or an hour,” the actress told Fox News Digital recently.

In addition, she also tries to hit the tennis court often!

“I play tennis five times a week sometimes. And so that’s very, very important,” Donna revealed.

She also sticks to a certain diet, but has one food she can’t live without…

The Knot’s Landing star is also strict on what she eats, including cutting back on sweets!

“I’ve always been anti-sugar,” she dishes. “I read a book a long time ago called ‘Sugar Blues’ that really talked about the sugar industry and everything, and I have stayed away from it ever since.”

“It’s a lot of stuff. You got to work at it,” she adds.

However, she can’t cut back on one food.

“I’m a Doritos addict,” Donna says, adding the Nacho Cheese flavor is her favorite.

“I mean, it’s not good for you. It’s not. You know, I know I shouldn’t do it,” she shared.

Her love of Doritos has even followed her to the sets she’s been on.

“Different sets that I’ve been on… for some reason, they know — they always got a bag of Doritos in the trailer for me… it’s really funny. But I’ve never lost that,” she said. “I don’t eat them as much as I used to. But they’re still a treat.”

Donna recently opened up about her OnlyFans journey so far, and the amount she’s made from being on the platform has been revealed, despite not charging for her subscription. Find out more here!
