Sydney Sweeney built a gym in her house just to prepare for Christy role

Sydney Sweeney built a gym in her house just to prepare for Christy.

The 28-year-old actress plays boxer Christy Martin in the movie and she was “excited” to totally transform herself for the role.

She told Britain’s OK! magazine: “I was excited to do it.

“I wanted desperately to do Christy justice and to make her proud.

“I really love to play characters that I can disappear into and just totally transform.

“I threw myself into every aspect of this character.

“I built a gym in my house. I had a professional boxing trainer, a weight trainer and a nutritionist. I was working hard every day to get where I needed to be physically.”
