What’s the secret to having a killer body like Jennifer Aniston’s? Daily exercise, healthy eating, and lots of diligence. The 43-year-old recently revealed her healthy living regimen for the March issue of InStyle, telling the magazine that she likes to “mix it up.”

“I work out almost every day, at least five or six days a week,” she says. “I do 40 minutes of cardio: spinning, running, the elliptical, or a combination of all three. Then I do Pilates one day a week, and I do yoga in addition to that, three days a week.”

When she travels, Aniston also likes to take some of her routine with her — something the exercise-obsessed Rev. Al Sharpton would surely agree with.

“I take 8-pound weights with me whenever I’m staying in a hotel,” she says. “It’s always good to do arm exercises when you’re watching television or talking on the phone. I also love to stretch before I go to bed, and usually throw in a couple of sit-ups.”

As for diet, Aniston proves once again that the secret to a healthy bod lies in less meat, more vegetables, and the occasional cheat.

“Most of the time I eat things like salmon or other fish, quinoa, lentils, and green vegetables. You’re told to avoid fried food, but I don’t always,” she shares. “I had Mexican the other night and ate everything you can imagine! I also take Omega Cure liquid fish oil and resveratrol, which is supposed to be good for your heart.”

Aniston, who is currently dating actor Justin Theroux, recently purchased a $24.9 million home in Bel Air set on three acres and offering unobstructed ocean and city views. She can next be seen in the film “Wanderlust” opposite Paul Rudd.
