Sydney Sweeney Reveals the Demands of Preparing for Her Role as Christy Martin
To fully embody Christy Martin, Sydney Sweeney undertook a rigorous training and transformation process that dramatically altered her body and mindset. Speaking to W Magazine, Sweeney described how her body changed:
“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.” —Sydney Sweeney, Actress
She explained that the intense physical preparation lasted about three and a half months and involved a demanding daily routine. This included weight training in the morning, two hours of kickboxing midday, and another weight-training session at night, all while maintaining a strict diet to gain muscle mass.
“I came onboard to play Christy, and I had about three and a half months of training,”
“I started eating. 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.” —Sydney Sweeney, Actress
Her background in sports helped her adapt quickly to the physical challenges required. She shared how her childhood involvement in various athletic activities prepared her for the role:
“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.” —Sydney Sweeney, Actress
