"Hot Tub Fine Machine (ps reminding you I have TWO university degrees)," the star first joked as she posed in the swimming pool.

She later updated the caption to simply two winking emojis.

Last week, Rebel - who has reportedly lost more than 18 kgs this year - showed off her stunning figure in skin-tight turquoise activewear.

It comes just days after the Pitch Perfect star challenged Hemsworth brothers Chris and Liam as Australia's "latest action hero".

Rebel publicly made a New Year's resolution at the start of the year to ditch her unhealthy eating habits and kickstart a new fitness journey.

She wrote on Instagram: "Okay so for me 2020 is going to be called 'The Year of Health'.

"So I put on the athleisure and went out for a walk, deliberately hydrating on the couch right now and trying to avoid the sugar and junk food, which is going to be hard after the holidays I've just had but I'm going to do it! Who's with me in making some positive changes this year?"

In an interview with E! earlier this year, her trainer Jono Castano explained he had created a specific programme for Wilson covering six days.

He said he encouraged his clients to work out daily for 45-minute sessions, noting "results come through consistency".

His personalised programme for the star includes high-intensity interval training, mobility, weights, resistance, technique and tempo. Wilson has one day off a week to rest her body.
