A young woman is using an outdoor exercise machine on a beach at night. The machine is a cross-country skier. She has brown hair pulled back in a ponytail, wears a tan tank top, a denim skirt, and brown sandals, and carries a brown purse slung across her shoulder. She's holding onto the machine's handles and stepping on the foot pedals, moving her legs in a walking motion. The exercise area is sandy, surrounded by palm trees and lit by string lights and colored umbrellas.
