Hollywood star Sydney Sweeney has revealed the remarkable physical changes her body underwent while preparing to portray boxing legend Christy Martin in an upcoming biopic.
The acclaimed actress, who has become one of the entertainment industry’s most sought-after talents in recent years, opened up about her intensive training regimen during a recent interview with W Magazine.
“My body was completely different. I loved it,” Sweeney shared with enthusiasm. “I joined to play Christy and had about three and a half months of training. I started eating. I did weight training in the morning for an hour, kickboxing at noon for about two hours, and then again weight training in the evening for an hour.”
The physical transformation surprised even Sweeney herself, who noticed significant changes to her physique. “My boobs got bigger. And my butt got huge. It was crazy!” she revealed candidly. “I’m normally a size 23 in jeans, and I was wearing a size 27. I was like, ‘Oh, my God.’ But it was amazing: I was so strong, like an incredible force.”
The untitled biographical film, directed by David Michôd, chronicles the life and career of Christy Martin, one of America’s pioneering female boxers whose professional journey spanned from 1989 to 2012. Martin is celebrated for breaking barriers in women’s boxing while simultaneously battling significant personal challenges.
Martin’s story goes beyond her athletic achievements. She survived domestic violence at the hands of her former husband, Jim Martin, including a shooting incident in 2012 from which she fortunately recovered. Following this traumatic experience, Martin divorced her husband and continued to cement her legacy in boxing history.
Sydney Sweeney isn’t just fighting in the ring—she’s battling online cruelty with the same intensity. Sweeney found herself the target of trolls when candid sunbathing photos went viral. Critics were quick to mock her physique, seemingly unable to separate character preparation from personal image. In response, Sweeney released a fierce montage on Instagram featuring her grueling training regimen and a clear message: she’s strong, unapologetic, and not backing down.
Her passion for cheese and self-described “adult Lunchables” only fueled the fire for critics, but Sweeney leaned in, showcasing her strength, both physically and emotionally. Drawing on her martial arts roots that began in her early teens and years of serious training, Sweeney reminded fans and haters alike that she’s more than just a face—she’s a force.
