The photos came from a fitness session she had with her trainer Gunnar Peterson.

The 40-year-old Australian comic, who is currently based in America, said in the clip: “I just slunk into this little catsuit number because I’m about to do a workout with my US trainer Gunnar Peterson.”

The actress also posted photos with her trainer, adding a yellow hoodie over her outfit.

Peterson has worked with other high-profile celebrities such as Kim Kardashian, Jennifer Lopez and Sofia Vergara.

Wilson has lost 18kg to reach her goal weight of 75kg, but she has also discussed the sad side that came with it.

While chatting to 2Day FM’s new breakfast radio show Hughesy, Ed and Erin recently, Rebel revealed how differently she gets treated now that she’s lost weight.

Erin Molan asked the comedian: “Hey I’d love to know … we have all seen you physically change from the outside, how has it changed you on the inside? How has it changed you as a person?”

“It’s interesting Erin, I like to think I looked good at all sizes and I’ve always been confident,” Rebel began. “It’s not like I wasn’t confident and now I’m confident.

“What’s been really interesting to me is how other people treat you. Sometimes being bigger, people didn’t look twice at you and now that I’m in good shape people offer to carry my groceries to the car and open doors for you. Is this what other people have experienced all the time? That to me has been really interesting.”

She continued: “I also find it interesting that people pay so much attention to a weight loss transformation when there is so much going on in the world.”

Wilson stuck to a gruelling working routine and strict diet in 2020 to get in shape.

While fans were mostly supportive of her health overhaul, in December she that revealed not everybody in the film industry was behind the change.

In her most candid discussion yet, Wilson sat down for an hour-long Instagram Live to discuss her “year of health”.

“Industry-wise, there were a lot of people who wanted me to stay as Fat Amy,” Wilson explained, referring to her character in the movie franchise Pitch Perfect.

“And at the end of the day, it is my life and my body and Hollywood had in a way typecast me but I didn’t want to stay like that.

“It makes me sad sometimes that I didn’t value myself enough before all of this to get healthy.”
