Sydney Sweeney showed off her muscular physique on Friday afternoon after bulking up to play boxing legend Christy Martin in a new biopic.
The actress, 27, rocked a stretchy black one-piece as she enjoyed a sunny stroll with her shirtless fiance Jonathan Davino, 41, and pals near her $13 million Florida Keys mansion.
She had a black sweatshirt tied around her trim waist and a baseball cap over her wavy blonde hair.
The Euphoria star appeared makeup-free and kept a pair of designer shades over her blue eyes.
To complete her athletic look, Sweeney threw on a pair of stylish lace-up sneakers.
Sweeney has been hunkered down in Florida while enjoying a brief reprieve from her busy Hollywood schedule ahead of the Christmas holiday.
