three people engaged in a dance movement inside what appears to be a dance studio. The room has a wooden floor, grey walls, and a small black rectangle resembling a monitor or picture frame on the left wall. The studio lighting is mainly purple, with a blue pillar of light illuminating the right wall. The central figure is a red-haired woman wearing a white long-sleeved shirt and grey sweatpants. She begins on her knees, arching her back downwards towards the floor before returning to an upright position. To her right, another person dressed in a dark-colored shirt and pants is engaged in a similar movement, though only their upper body is visible. To the left of the red-haired woman, a third person is also engaged in the dance exercise. The dance involves bending over and arching the back.
