A group of children, predominantly boys, are lying on a blue and yellow mat in a gymnasium, participating in a physical training session. The children are dressed in athletic wear, mostly blue and black t-shirts and shorts. Some are lying on their backs with their arms at their sides, while others are positioned on their stomachs. In the background, there are various pieces of gym equipment, including mats, weight machines, and punching bags. A large banner with the word "СПАРТА" (Sparta) is visible on the back wall, along with the Russian flag. The lighting in the gymnasium appears to be standard fluorescent lighting. The overall impression is that of a martial arts or physical education class for young students.
