Sydney Sweeney has revealed everything she did to achieve her intense post Christy transformation.

The Euphoria-famed actress recently gained weight for her role as boxer Christy Martin in her movie ‘Christy.’ The actress shed a whopping 30 pounds in just two months of finishing filming.

Speaking to People magazine, the 28-year-old opened up on the “strict” routine she followed after wrapping up her boxing biopic, in which gaining weight for her role was a requirement.

“I had to be really strict with myself,” the Immaculate star said, recalling the challenge of losing the muscle and weight she had gained for the film.

“When I was training, it was really hard to put on all the weight. I was eating so much food like, everything you could possibly imagine.”

Sweeney explained that what really helped her in training was consuming “protein shake after protein shake” and plenty of creatine, which she admitted caused her to bloat. “And then, I just stopped all of that,” she revealed.

The actress noted that she was able to kickstart weight loss immediately after the end of her harsh training.

“When you stop working out and taking all your protein shakes, you lose muscle super fast,” she said. “It’s the first thing to go before fat. So that, I dropped within two weeks.”

The transformation was both physically and mentally hard and required extreme discipline for her to get back to her original figure.

Sweeny’s boxing biopic film was released on Sept 5th, where the plot revolved around a gritty female boxer, Christy Martin. Her role in the biopic required months of strength training and major weight gain with a calorie-heavy diet.
