In a remarkable transformation for her upcoming role, actress Sydney Sweeney underwent intense physical training to portray boxing legend Christy Martin in an untitled biopic directed by David Michôd. Known for her roles in Euphoria and The White Lotus, Sweeney immersed herself in the life of one of America's most successful female boxers, gaining over 30 pounds and altering her physique.

In an interview with W Magazine, Sweeney detailed the rigorous regimen she undertook to embody Martin. "I came onboard to play Christy, and I had about three and a half months of training," she said. "I started eating. I did weight training in the morning for an hour, kickboxing at noon for about two hours, and then another weight training session at night for an hour."

The physical demands of the role led to changes in Sweeney's body. "My body was completely different," she revealed. "None of my clothes fit me. I normally wear a size 23 in jeans, and I was wearing a 27. My breasts grew. And my butt got huge. It was crazy! I thought: 'Oh my God.' But it was amazing: I was so strong, crazy strong!"

Despite the transformation, Sweeney found the experience empowering. "I loved it," she stated. "It was amazing: I was so strong, like crazy strong." Her commitment to the role impressed director David Michôd, who praised her work ethic and dedication. "Sydney trained her butt off to play the role," he said. "The beauty of Sydney is that she came to work every day with her tail wagging, ready to start. No matter how hard it was, she was like a ray of sunshine."

The film chronicles the life of Christy Martin, a trailblazing boxer who rose to fame in the 1990s. Martin became the first woman signed to a promotional contract by boxing promoter Don King and was the first female boxer to appear on the cover of Sports Illustrated. Her career was marked by 49 victories and titles, including the women's super welterweight world title in 2009.

However, Martin's personal life was fraught with turmoil. In 2010, she survived a brutal attack by her then-husband and manager, James Martin, who stabbed and shot her. He was later convicted of attempted second-degree murder and sentenced to 25 years in prison. Martin's story is one of resilience and survival, themes that Sweeney is passionate about conveying.

Sharing her thoughts on social media, Sweeney wrote, "Over the past few months, I've been immersed in training to bring to life the story of an incredible woman—a true champion who fought battles both inside and outside the ring. Her journey is a testament to resilience, strength, and hope, and I'm honored to step into her shoes to share her powerful story with you all."

Joining Sweeney in the film is Ben Foster, who portrays James Martin. The cast also includes Merritt Weaver, Katy O'Brien, Ethan Embry, and Tony Cavalero. The biopic aims to delve deep into Martin's rise in the boxing world and her personal struggles, offering an unflinching look at her life.

Sweeney's background in sports and outdoor activities contributed to her preparation for the role. As a child, she participated in skiing, wakeboarding, soccer, and softball. "My mother said from a young age that I should love as many things as possible," Sweeney recalled. "And so I fell in love, again and again, with sport."

The film does not yet have a release date, but anticipation is building as fans await the opportunity to see Sweeney's transformation on screen. Director David Michôd expressed his enthusiasm for the project, stating, "Our film is a wild mix of inspiring underdog sports-world story and personal saga."

Christy Martin had an impact on the sport. Hailing from West Virginia as the daughter of a coal miner, she broke barriers in a male-dominated field. In 2020, she was inducted into the International Boxing Hall of Fame, the first year women were included on the ballot.
