She required weight change in order to fully portray the athlete’s muscular frame
Emma Stone had to get in shape to portray tennis legend Billie Jean King in the film. The athlete’s powerful frame necessitated weight gain for her to match. What is the quickest and most effective way to do this? High-protein shakes. Jason Walsh, Emma’s trainer, noted that “she was looking forward to them.”
In order to prepare for this biographical sports picture, Emma Stone worked out twice a day, four or five days a week. Critics praised her performance.
