Sydney Sweeney earned her spot in the ring.
The actress, 27, opened up about her dramatic transformation to play professional boxer Christy Martin for the upcoming biopic being directed by David Michôd.
'I came onboard to play Christy, and I had about three and a half months of training,' Sweeney said in a new W Magazine cover story, which noted that she gained over 30 pounds for the role.

'I started eating,' she continued. 'I weight-trained in the morning for an hour, kickboxed midday for about two hours, and then weight-trained again at night for an hour.'

Sweeney shared that her 'body was completely different' as a result.
'I didn't fit in any of my clothes. I'm usually a size 23 in jeans, and I was wearing a size 27,' she said. 'My boobs got bigger. And my butt got huge. It was crazy! I was like, Oh my god.'

In October, Sweeney looked unrecognizable as the WBC super welterweight champ on the film's set in Charlotte, North Carolina.
The 'White Lotus' star rocked a short and curly brunette wig and wore a baggy zip-up, sweats and t-shirt.
Sweeney, per her W Magazine story, had to drop the weight she gained in just seven weeks before she started shooting Season 3 of 'Euphoria.'

'I hadn't ever seen her in 'Euphoria,'' Michôd, 52, told the outlet. 'I FaceTimed with her the other day when Sydney was in the makeup truck for the show, and I was stunned by the change in her appearance.'
'I had only seen her as an adorable, tough moppet with late-'80s hair, ready to box,' the director continued. 'Sydney was happiest when she was in the ring punching and being punched. It was shocking to see her being so glamorous.'

The biopic, written by Michôd and Mirrah Foulkes, will chronicle Martin's rise to fame in the boxing world. The cast also includes Ben Foster, Merritt Wever, Ethan Embry and Katy O'Brian.
Known as 'The Coal Miner's Daughter' because of her father's job, Martin made her boxing debut in 1989. She is credited for making women's boxing mainstream after taking on Deirdre Gogarty in front of cameras and a sold-out crowd at the MGM Grand in Las Vegas in March 1996.

But Martin's life took a turn in Nov. 2010, when her manager-turned-husband James, 66, stabbed her several times and shot her in the chest, leaving her for dead on the floor of her bedroom in Apopka, Florida. The then-42-year-old athlete survived the attack, and James was arrested days later and charged with attempted first-degree murder and aggravated battery with a deadly weapon.
Martin — who later came out as gay and married Lisa Holewyne in 2017 — was thrilled about Sweeney's casting in the film about her life.

'I think she is young, hot, talented and about to make a movie that in 20+ years, fathers will watch with their daughters to make them aware of domestic violence,' the athlete told TMZ last year.
Sweeney, for her part, told Deadline in May 2024 that she was inspired by Martin's story and was excited to 'train and transform my body' for the role.
