She regularly attends Pilates classes and is known to frequent exclusive gyms in Sydney’s eastern suburbs.

Model Madeleine Holtznagel, 27, showed she’s more than just a pretty face as she showcased her remarkable upper body strength during a backyard gathering on Sunday.

The partner of billionaire pub tycoon Justin Hemmes, 50, shared an Instagram Stories video of herself climbing a rope attached to a swing hanging from a tree.

Other guests watched from the ground as Madeleine performed the impressive stunt in a cream crop top and matching cargo pants. 

She completed her look with a pair of trendy sunglasses and went barefoot so she could properly cling to the knotted rope.

‘Holtznagel Challenge,’ she cheekily captioned the video, adding a crying/laughing emoji. 

It comes weeks after Madeleine celebrated her 27th birthday party with a lavish bash at Justin’s $100million home in Vaucluse, Sydney.

Following the festivities, Madeline revealed on Instagram that her beau had also bought her two llamas as a tribute of his love.

Madeline shared snaps of herself meeting the adorably fluffy farm animals.

Madeline and Justin quietly began dating in 2019, a year after the publican made his debut on the Financial Review Rich List with an estimated net worth of $951million.

Back in June, Madeline teased her Instagram followers by wearing a ring on her wedding finger while cuddling up to Justin as they enjoyed a bowl of Udon noodles together at a restaurant in Japan. 

The bling appeared to be a pretty turquoise dress ring she teamed with her outfit.  

Another photo saw her wearing a different ring on the same finger as she posed in front of a bathroom mirror for a selfie.
