woman in a gym

woman in a gym. She is wearing a grey long-sleeved shirt with a logo on the sleeve, and her hair is pulled back. In the first shot, she is looking directly at the camera. She then appears to move to a position on the floor near a mirror. Lying on a blue mat, she faces the mirror, revealing a black foam roller next to her. She holds up her phone, showing a video or image on the screen. In the background, another person is using a treadmill. The gym has typical equipment, including a stair climber and treadmills, and is lit with bright overhead lights. The mirror reflects the gym's interior, including a red arrow sign.
