On Friday, Sydney-based personal trainer Jono Castano Acero posted a photo with the Australian actress, saying he was proud of Wilson for sticking to it.

"Friday vibes, but @rebelwilson has been putting in the yards 7 days a week! Proud of you gurl," he wrote.

"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!" she wrote. "Who's with me in making some positive changes this year?"

"These people are like, the best dancers in the whole world, so they can't cool their muscles down or they could get an injury and they'd be out of the film ... So, they'd heat up the set like a sauna so we would never cool down, but made it pretty uncomfortable," Wilson said in the interview.
