Sydney Sweeney Shares Her Intense Training Experience as Christy Martin
For her role as Christy Martin, Sydney Sweeney committed to months of demanding preparation that completely changed her physique. Speaking with W Magazine, she detailed the significant shift in her body, calling the transformation “crazy.” Sweeney’s approach to inhabiting the role meant a rigorous daily routine and strict training schedule, all with the goal of authentically portraying the legendary boxer on screen.
“I didn’t fit in any of my clothes. I’m usually a size 23 in jeans, and I was wearing a size 27. My boobs got bigger. And my butt got huge. It was crazy! I was like, ‘Oh my God.’ But it was amazing: I was so strong, like crazy strong.”

While the physical changes were dramatic—forcing her to adjust to new clothing sizes and a different reflection in the mirror—Sweeney expressed genuine enthusiasm for the process. She found the experience of building strength and endurance to be incredibly rewarding, even if the challenge was significant. After the movie wrapped, she was tasked with losing the additional weight in just seven weeks for another upcoming project, but reflected fondly on her time spent training as Christy Martin.

Her daily schedule was tightly organized, balancing different forms of exercise throughout the day to build strength, endurance, and boxing skills.

This regimen didn’t come entirely out of the blue for Sweeney. She has a strong background in sports and staying active, which helped her meet the demands of the role. Her athleticism was honed through years of various outdoor and competitive activities, and these past experiences contributed to her transformation for the movie.
“I love sports. I love being outside. I was on the ski team, and I wakeboarded,”

“I slalom ski on water. I was on the soccer team and the softball team. And then my parents got me into grappling, which is like wrestling, and kickboxing. I was the only girl at the dojo. I trained there from 13 until about 19. I fought all guys. I liked to think that if sh—t went down, I might be able to step up.”
