Here's a description of the video: A young woman in a sports bra and leggings stands in what appears to be a locker room. She is fair-skinned with dark hair pulled back in a ponytail. She smiles at the camera. She holds up a plastic water bottle that is partially filled with a purplish liquid, perhaps a sports drink. She inspects the bottle, then shakes it vigorously. The locker room has red lockers lining the wall, a wooden bench, and some personal items on the bench. The lighting is bright and uniform.
