Sweeney Packs On Muscle, Embodies Boxing Legend Christy Martin

Toronto, canada – Sydney Sweeney has revealed the intense preparation she undertook to accurately portray boxing icon Christy Martin in the forthcoming biopic, Christy. The film details martin’s celebrated career, her rise as a dominant force in women’s boxing during the 1990s and 2000s, and her harrowing experience surviving domestic violence and a life-threatening attack by her husband and former trainer.

Dramatic Physical Transformation

Speaking at the film’s premiere at the Toronto International Film Festival on Friday, September 5, Sweeney disclosed that she gained more than 30 pounds in three months to authentically represent the physicality of a professional boxer. She committed to a demanding training regimen that included multiple daily sessions with a boxing coach, alongside specialized work with weight trainers and a nutritionist. “I trained two to three times a day, every day, and then while I was filming, I trained, as well,” Sweeney stated.

director David Michôd humorously noted that a significant part of Sweeney’s caloric intake involved frequent visits to Chick-fil-A. Sweeney corroborated this,adding,”A lot of smuckers,a lot of milkshakes,a lot of protein shakes.But it was incredible being able to fully embody such a powerful woman.”

Balancing Persona and Reality

Christy Martin, who served as a consultant on the project, emphasized the distinct dichotomy between her public boxing persona and her private self. She praised Sweeney’s ability to capture this nuance. “Christy the boxer was just the persona, very bombastic and very egotistical, but that is not who I am. I am actually very shy and reserved,” Martin explained. “I have these two different parts of my personality, which I think is why Sydney Sweeney does this awesome job. She got to be this totally different person that none of you expected.”

Martin continued, “She wasn’t the lovely, sexy Sydney. She was the tough, rugged Christy in this movie.”

Release Details and Current Controversy

Christy is slated for release in the United States on November 7. While a United Kingdom release date is yet to be announced,the film will be showcased as a gala screening at the London film Festival on October 17.

Sweeney recently navigated a separate public matter at the film festival, firmly declining to address questions concerning the recent controversy surrounding her partnership with American Eagle jeans. “The movie’s about Christy, and that’s what I’ll be there to talk about,” she asserted.

The euphoria star faced criticism for her involvement in the brand’s advertising campaign,which drew accusations of racial insensitivity. Public figures such as Lizzo and Doja Cat voiced their disapproval, and Sweeney was reportedly heckled at a prior film premiere. American Eagle responded with a statement emphasizing the campaign’s focus on the jeans themselves. The episode also attracted attention from former U.S. President Donald Trump, who publicly praised Sweeney’s involvement.

Sweeney additionally responded to critiques regarding another endorsement deal, defending her decision to market soap infused with her bathwater.
