Tiffiny Hall is turning 40 in style, celebrating with a getaway to Bali.

The celebrity trainer took to Instagram on Thursday to share a gallery of snaps from her sun-soaked escape.

In one photo, Tiffiny showed off her incredible figure in an electric blue bikini, proving that age is just a number.

She accessorised the look with a chic pair of sunglasses and tied her blonde locks up into a ponytail.

Tiffiny marked the milestone birthday on the island resort with daughter Vada, one, and son Arnold, six, who she shares with husband Ed Kavalee.

She simply captioned the post 'This is 40 xoxo.'

Earlier this year, the celebrity fitness trainer took to Instagram to share her incredible physique in a vibrant bikini after losing a staggering 40kilos following the birth of her second child.

In the image, Tiffiny is seen standing proudly, coconut in hand, in striped swimwear on a beach.

The former Biggest Loser star captioned the image with some heartfelt words.

'My intention last January was to enjoy the journey back to fitness and feeling strong,' she wrote.

'It feels amazing to be here, a year later, having had so much fun with the love and support of my friends, family and trainers. It really is about the journey, not the destination.'

Her approach to wellness has always been holistic, and this time it was no different.

Tiff explained that her accomplishment was not with a fad diet or rigorous scale monitoring, but by celebrating non-scale victories.

'Running my first KM, keeping up with my kids at the park, learning to squat again after my knee procedure, fitting into an old pair of jeans,' Tiffiny explained.

She also encouraged the importance of enjoying each step taken towards a healthier self.

'Thank you for all your lovely messages of motivation and support throughout the year. It really kept me going,' she writes, acknowledging the power of collective support in personal journeys.
