Sydney Sweeney gains 16kg for boxing film role

Actress Sydney Sweeney has undergone a significant physical transformation to prepare for her role in the upcoming film ‘That’s Why the Lady Is A Champ’, directed by David Michôd. To portray boxer Christy Martin, who helped bring women’s boxing into the mainstream, Sweeney gained 16 kilograms of muscle mass.

Sweeney reported that she spent three months training with professionals, lifting weights, and consuming high amounts of protein. She even converted her grandmother’s garage in Idaho into a makeshift gym, complete with a boxing ring and heavy bags, to facilitate her training.

In discussing the role, Sweeney noted parallels between herself and Martin regarding the distinction between public and private personas. She emphasized the struggle women face in meeting societal expectations while maintaining their true selves.
