In a brightly lit indoor gymnasium or training hall, a group of children, predominantly girls, are engaged in a gymnastic or acrobatic exercise. They are positioned in a line on a blue mat, with some individual yoga mats beneath them. The children are performing a "crab walk" or a similar inverted movement, propelling themselves forward using their hands and feet while their torsos face upwards. An older girl or instructor, dressed in black activewear, stands at the front, initially demonstrating or observing the children. She then steps aside as the children continue their movement. The room features high white walls, large floor-to-ceiling windows on the right revealing an urban landscape outside, and a modern ceiling with strip lighting and ventilation. A wooden floor is visible along the bottom edge of the frame, bordering the blue mat. The children appear focused on their exercise. The scene takes place in Khimki, Russia.
