In a brightly lit indoor gym, several children participate in an exercise on a mat with alternating blue and yellow squares. The children are lying prone with their arms extended to their sides, engaging in a paddling motion. In the foreground, a boy wearing a black t-shirt and gray shorts is seen performing the exercise. Behind him, other children are similarly engaged in the activity. The gym features a high ceiling, red support beams, and banners displaying text in a Cyrillic alphabet. In the background, various gym equipment and objects like a soccer goal are visible.
