Sydney Sweeney is no stranger to taking on challenging roles, but her latest transformation for the boxing biopic Christy has taken it to a whole new level. Known for her breakout role in Euphoria and starring in The White Lotus, Sweeney is making waves once again, this time with a dramatic physical transformation that is as gritty as the story she’s about to tell. In her latest role as Christy Martin, the legendary boxer, Sweeney didn’t just act—she completely immersed herself in the life of a fighter, undergoing a rigorous regimen that reshaped her body and mind.
From Hollywood Glam to Gritty Fighter
To portray Christy Martin, a pioneer in women’s boxing, Sydney Sweeney had to step far outside her comfort zone. Known for her glamorous red carpet appearances and roles that often require polished performances, this was no small feat. To embody Martin, who famously fought her way through personal and professional battles in the ring, Sweeney’s preparation included a strict diet, intense physical training, and even physical setbacks that made her journey to becoming Christy all the more authentic.
Transformation to Fighter
Sydney’s transformation was not only about getting in shape—she had to gain weight to properly reflect Christy Martin’s build at the height of her career. In an interview, Sweeney revealed she put on 35 pounds in just a few months, a challenge that was mentally and physically taxing. “I had to focus on eating a lot of protein, and that meant sometimes eating food I don’t normally enjoy. But it was necessary to take on this transformation,” Sweeney shared.
This weight gain was crucial for portraying Christy Martin’s true physique, especially since the boxer was known for her muscular, athletic build. Sydney also worked with a team of trainers who focused on functional fitness and boxing techniques. The goal wasn’t just to gain weight, but to make sure Sweeney was able to move like a fighter in the ring.
Overcoming Injuries and Physical Challenges
In addition to the physical changes, Sweeney encountered a more serious challenge during her training—she suffered a concussion on set. This was a sobering reminder of just how committed she was to delivering an authentic portrayal of Christy. Boxing is a brutal sport, and Sweeney’s injury showcased the risks that come with committing to a physically demanding role. Despite this setback, Sweeney pushed through, showing her dedication not only to the film but also to her personal growth as an actor.
The concussion didn’t deter Sweeney from her goal. Instead, it became a testament to her unwavering commitment to embodying her character. While this physical toll may seem extreme to some, it highlights the level of dedication required to fully bring a story like Christy Martin’s to life.

While the physical training was intense, Sweeney also had to tap into her mental toughness to keep going. “It’s not just about lifting weights or doing cardio; it’s about learning the mental toughness that comes with fighting. It’s about becoming someone who can take a punch, literally and figuratively,” Sweeney said. The mental transformation required for this role was just as significant as the physical one, and it mirrored the resilience that Christy Martin had to show in her career.
This role also pushed Sweeney to new emotional depths. As an actress, she has always portrayed complex characters, but Christy Martin’s real-life story brought a new layer of emotional depth that required Sweeney to confront themes of strength, vulnerability, and survival. For someone who has made a name for herself in the world of high-fashion and red carpet glam, this was a stark contrast.
Preparing for a Boxing Legend
Taking on a role as significant as Christy Martin was never going to be easy. Martin, known as “The Coal Miner’s Daughter,” broke barriers for women in a male-dominated sport. She became a symbol of resilience, perseverance, and grit—qualities that Sydney Sweeney has had to channel in her own way throughout the preparation process.
From weight gain to boxing training, Sweeney’s commitment to this role shows that she’s not afraid to put in the work. She’s not just playing a boxer—she’s becoming one. Sydney is showing that behind the glamorous red carpet appearances and fashion campaigns, there’s a true artist dedicated to her craft.
The transformation is far from over. Sweeney’s commitment to her physical and mental preparation for Christy will continue to inspire aspiring actors and fitness enthusiasts alike, proving that success in Hollywood isn’t just about looking good; it’s about enduring the physical and emotional challenges required to play some of the toughest characters in film.
Sydney Sweeney’s journey to becoming Christy Martin is a powerful reminder that true transformation in Hollywood goes beyond the screen. It’s about embracing the grit and determination that real-life heroes, like Christy Martin, possess. For Sweeney, this role has pushed her boundaries, not just as an actress, but as a person willing to sacrifice her own comfort for the sake of a great performance.
