American actress Sydney Sweeney has detailed her intense physical transformation to portray boxer Christy Martin in an upcoming biopic. In a recent interview with W Magazine, the 27-year-old actress revealed she gained 30 pounds to accurately represent the professional boxer’s muscular physique.
According to People, the transformation process began approximately three and a half months before filming, during which Sweeney committed to a rigorous daily training schedule. Her routine consisted of morning weight training for an hour, followed by two hours of kickboxing at midday, and concluded with another hour of weight training in the evening.
