Jennifer Aniston, 51, shows off her jaw-dropping physique in a crop top and leggings

She’s long been an advocate for healthy living and her physique is proof of her dedication.

Jennifer Aniston shows off her incredible physique in a stunning new campaign shoot after becoming the face of Vital Proteins.

The shoot sees the 51-year-old wowing in a crop top and leggings as she demonstrates some yoga moves and goes for a run.

One shot shows the Friends icon flaunting her toned arms and waist in a green sports bra as she jogs in sunlight.

Another demonstrates Jennifer’s love of yoga as she poses on a mat in the same sporty ensemble.

The gorgeous star’s impressive abs are on show in the third photo as she changes into a knotted white crop top and stretches. 

In addition to becoming the face of the brand’s December campaign, Jennifer will also be taking on the the role of its Chief Creative Officer.

The actress announced that she was teaming up with the wellness brand on Wednesday.

The actress shared a photo on Instagram of herself showing off all her Vital Proteins products to mark the partnership. 

Jennifer was dressed casually in a white tank top in her picture as she held a basket of various jars on her lap.  

‘I’m so excited to (finally) announce that I’m joining @vitalproteins as the Chief Creative Officer,’ she began her caption.

‘Years ago I started using Vital Proteins regularly… so when the opportunity presented itself to be a part of the brand in a bigger way, I jumped on it.

‘I’ve always been an advocate for finding wellness from the inside out — and I’m so happy to share the importance of collagen,’ she wrote, before promising there would be more to come.   

‘Our strength starts from within, so I choose good nutrition and the right supplements to start off my day,’ Jennifer shared with People. 

Collagen is a naturally occurring protein in the body that’s present in bones, skin, muscles, tendons and ligaments, and collagen supplements may help with increasing muscle mass and skin elasticity.

Last year, Jennifer’s personal trainer Leyon Azubuike shared that his advice for the actress’ diet included eating plenty of healthy fats.

‘I love avocados, coconut oil, salmon, fish oil — anything that’s a good form of fat is great,’ he told Women’s Health. ‘For me, I stick to 1.7 grams of carbs and 2 grams of protein per my kilo weight to support muscle-building.’

In 2016, the Morning Show star confessed to Elle that pasta was her favorite food when she felt like cheating on her diet.

‘Pasta has taken over as my new favorite go-to-town food,’ she said, adding that she was a fan of carbonara.

‘I’ve learned how to make it,’ she continued. ‘And it’s not that bad for you! It’s just an egg, parmesan cheese, and a little pasta water. And we substitute turkey bacon for real bacon, so, you know.’
