Simone Holtznagel looks fitter than ever after shedding an incredible 10kg.

The 29-year-old model flaunted her slim frame Tuesday as she headed to her personal trainer friend Jono Castano’s ACERO gym for a morning sauna session.

Taking to Instagram, the blonde bombshell posed in a skimpy black and white bikini while showing the peace sign in the mirror.

Her slim midsection and legs were on display, as were her noticeably slimmer arms and toned triceps.

She revealed in the caption that it was her first “sauna sweat” of the year.

Simone debuted her body transformation in August after losing weight over the course of 10 months with the help of PT Jono.

At the time, Jono dismissed any suggestion that her weight loss was too drastic, telling Chron Australia: “The way she got results wasn’t by starving herself; it was implemented through a structured program.’

Simone ate four meals a day and her diet was “very balanced, with all of her macronutrients included in each meal,” he explained.

The socialite resisted backlash after revealing her body transformation, but said at the time she had ignored her critics.

“People have commented that it ‘triggers’ and ‘before and after’ doesn’t belong in 2022…” she told the Daily Telegraph.

“I figured what we wouldn’t do in 2022 was comment on other people’s bodies,” she added.

Jono and Simone met a few years ago when she was one of the trainer’s most well-known clients.

They initially kept their romance under wraps before going public in May when they were spotted kissing at Mimi’s restaurant in Coogee.

Jono was previously in a relationship with ACERO gym owner Amy Castano.
