Jennifer Aniston Says This Is How She Maintains Her Timeless, Flawless Body

As a woman in my 20s who can barely survive the climb to my fifth-floor, walk-up apartment, Jennifer Aniston's eternal youth amazes me on a small-child-seeing-sleight-of-hand-for-the-very-first-time level.

The actress posed for a stunning photo shoot, complete with avian accessories, in April's issue of Harper's Bazaar and shared some insight on how #SelfCare led her to feel better in her 40s than she did in previous decades.

The “Mother's Day” actress works out five days a week, employing the tried-and-true technique of alternating her focus between different exercises targeting different parts of her body for short periods of time.

Beginning with a "15-minute quad thing," Aniston said,

I do 15 on the elliptical, 15 Spinning, then I do 15 run. And then I do portions of the Body by Simone DVD for floor work. It's so freakin' hard, it's unbelievable.

When it comes to food, Aniston said she loves guacamole and margaritas, but avoids sugar and tries to steer toward salads with protein or chicken burgers wrapped in lettuce. An active lifestyle and a straightforward, healthy diet free of fad techniques helped her reach a sweet spot at 47.

She explained,

I feel better in my 40s. Not only do you feel better in your body physically, but you're mentally better. Because, say, in your 20s, you didn't know sh*t. For me, in my 30s I was just trying to figure it all out. Then when you hit 40, you're like, 'Oh, [OK]. I got this.'... There are women who've hit 50 who are stunners, like shocking. We just take better care of ourselves.

The secret to Aniston's agelessness doesn't lie merely in diet and exercise. The notion of #SelfCare extends to her career moves as well.

She said,

There was a time when I worked and worked and worked. I loved it… I'm trying to be better at [saying no].

We're not all in the position to ease up on our work schedules, but incorporating the Jennifer Aniston Principles of Eternal Youth into our own day-to-day lives in small doses could help us all feel a little happier and healthier.
