She has undergone a dramatic transformation since first entering the public eye back in 2014 as a contestant on The Bachelor.
And after slimming down following her stint on the reality dating show, it appears Sam Frost is now fitter than ever as she showed off her very trim physique over the weekend.
Stepping out in a pair of thigh-skimming shorts and a low-cut vest top, the 26-year-old flaunted her toned arms and legs.
The TV star, who went on to find love with beau Sasha Mielczarek on The Bachelorette last year, kept her light brown locks swept back off her face with a baseball cap.

The blue-eyed beauty – who often shares make-up free snaps with her Instagram fans – appeared to have gone au naturel for the outing on Sunday.
But while she left her face cosmetics free, the TV star-turned-radio presenter looked as though she’d had a recent manicure and pedicure – showing off a light pink varnish on her nails.
She completed her look with a pair of leather sandals which accentuated her long, lean legs.
Sam was seen getting into a sparkly black Mini Cooper – potentially a replacement for her Hyundai Getz which had previously been parked by the roadside gathering dust for several weeks.

Meanwhile, her beau Sasha was spotted getting into a separate vehicle.
Dressed casually in a shirt, shorts and thongs, the construction manager completed his laid-back look with a pair of sunglasses.
But while the couple were seen heading off in different cars, Sasha later posted a sweet Valentine’s message to Sam on Instagram.
‘Happy Valentines to my beautiful girlfriend @fro01 ! Great to be back home in Bowral to escape the city,’ he wrote alongside a sweet selfie of the pair and the hashtags ‘#turtledove’ and ‘#willyoubemyvalentine’.

The couple appear to be going from strength to strength since hitting it off on The Bachelorette last year following Sam’s heartbreaking with Blake Garvey on The Bachelor.
Sasha even revealed last week that they have plans to move in together.
‘It’s not in the near future but it is close. We’re probably looking at April-May, mid-year type thing. It’s exciting,’ the 31-year-old told the Motherish.
The couple have been splitting their time between Sydney and the South Coast, where Sasha works, with Sam also darting around the country with 2DayFM.
The beauty took the helm of the station’s breakfast radio show alongside entertainment veteran Rove McManus late last year.
Happiness to heartbreak: Sam first appeared on TV screens on The Bachelor Australia in 2014 which saw Blake Garvey propose to Sam, only to dump her in favour of show runner up Louise Pillidge
