The video captures a group of approximately 10-12 young girls, likely children or pre-teens, engaged in a dance or exercise class. They are all uniformly dressed in black athletic wear, consisting of shorts and t-shirts or leotards. The setting is a well-lit dance studio, featuring a light-colored wooden floor and large mirrors covering the entire back wall and a portion of the side wall. Ballet barres are mounted along these mirrored walls. Overhead fluorescent lights illuminate the room, and speakers are visible on the walls. A small green mat or object is partially visible in the bottom right corner of the frame. The activity shows the girls performing synchronized movements. At the beginning of the clip, they are standing in preparation for a move. An instructor's voice is heard counting in Russian ("раз два" - one, two). Following the count, the girls swiftly transition to a floor exercise, bending down onto their hands and knees with one leg extended backward, demonstrating a focused and coordinated effort. The reflections in the mirrors show additional participants and multiple angles of the exercise. The girls appear focused and attentive to the instruction.
