Kicking off the work week with a morning workout, Hilary Duff was spotted arriving at her Los Angeles, California gym on Monday morning (September 22).

The former "Lizzie McGuire" star sported a striped top with red leggings and a pair of boots, toting a few handbags as she entered the facility and prepared to meet-up with her trainer.

Meanwhile, Hilary has also been keeping busy with the new Polish brothers comedy “Stay Cool,” in which she co-stars alongside Winona Ryder, Sean Astin, Chevy Chase and Jon Cryer.

In the film-in-the-making, Duff portrays the character of Shasta O’Neil, described as a sexy high school senior who fights with Winona’s character over the same man.
