A blonde woman, dressed in a black sports bra and red high-waisted briefs with red thigh straps, is lying on her left side on a light wooden floor. She holds a black smartphone in her right hand, facing a large mirror, and records herself. Her left leg is extended straight along the floor, and her right leg is initially bent. She then slowly extends her right leg straight upwards, forming a vertical line. Two silver poles are visible in the reflection behind her, indicating a studio environment with light walls and a window. A hand briefly passes in front of the camera, partially obscuring the view.
