Rebel Wilson shows off slim figure while boxing at the gym after losing 18kg

 She lost an estimated 18kg after vowing to make 2020 her ‘year of health’.

And on Thursday, actress Rebel Wilson proved she’s still working hard in the gym while showing off her boxing moves.

The Pitch Perfect star, 40, looked sensational in an all-black fitness ensemble as she flaunted her incredible weight loss in three images she shared to Instagram.

Rebel showed off her trim pins and slimmed down waist in a black pair of figure-hugging tights and a hoodie.

She coordinated her sporty look with a matching pair of purple runners and boxing gloves. 

Rebel appeared to be having a ball as she beamed while jabbing for the camera.

‘Fight Club,’ she captioned the fun images. 

It was revealed last month that The Hustle actress is believed to have lost 18 kilos in her weight loss journey so far.

According to a report by People in June, Rebel’s remarkable transformation is partially down to following the Mayr Method diet plan. 

A source told the publication she got ‘amazing results’ by changing her eating habits while staying at the luxe Austrian health and wellness retreat Vivamayr last year, and has continued on with the plan. 

‘It’s an approach that eliminates food intolerances, reduces sugar, encourages eating whole foods slowly, boosts the immune system and reduces inflammation,’ said the source.

‘She exercises with a personal trainer up to six times a week, goes on walks and is trying to up her protein intake nutritionally.’

They added: ‘I know she’s also been working on conquering her emotional eating patterns of behaviour.’  

Rebel announced she was embarking on a ‘health’ journey in January this year, and she’s been militant about sticking to her plan ever since.

‘Okay so for me 2020 is going to be called “The Year of Health”,’ she began in a post on Instagram at the time.

‘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!’

In a post on Instagram in May, Rebel revealed she was trying to get down to her goal weight of 75 kilos.

‘I’ll be honest with you guys – with my “Year of Health” mission I’m trying to get to 75kg’s,’ she wrote, adding, ‘There’s constant setbacks – but I’m working hard.’
