There are several train(er)ing days for Bella Thorne.

The 24-year-old half-Cuban America actress/singer has been cast in the dark comedy The Trainer, directed by Tony Kaye from a script by star Vito Schnabel and Jeff Solomon.

Thorne is part of a roster of new cast additions that includes Soo Joo Park, Brock O’Hurn, Laird Hamilton and Duke Nicholson.

The film currently in production, after nearly a decade in development, is based on an original story by Schnabel.

Unfolding over eight days of sleep-deprived chaos, it follows Jack (Schnabel), a down-on-his-luck fitness expert living with his mother in Los Angeles, who takes a maniacal swing at fame and fortune, trying to realize his version of the American dream.

Julia Fox, Steven Van Zandt, Taylour Paige, Stephen Dorff, John McEnroe, Gina Gershon and Luka Sabbat are also set to star.

Character details are being kept under wraps.

Thorne can currently be seen opposite Melissa Leo in Peyfa’s thriller Measure of Revenge, and will next be seen in Graham and Parker Phillips’ thriller Rumble Through the Dark, with Aaron Eckhart.

She’s previously appeared in the films Chick Fight, Ride, Midnight Sun, Assassination Nation, The Babysitter, Amityville: The Awakening, Boo! A Madea Halloween, The DUFF, Alexander and the Terrible, Horrible, No Good, Very Bad Day, and Blended.

Her television credits include Paradise City, Famous in Love, Shake It Up, Big Love, My Own Worst Enemy and Dirty Sexy Money.
