This image captures a close-up, static view of a weight stack from an exercise machine within a fitness facility in Sofia, Bulgaria. The central subject is a vertical column of dark-colored, rectangular metal weight plates. Each plate features a yellow label with black text indicating weight in kilograms. From top to bottom, the fully visible weight increments are: 2,5kg, 5kg, 7,5kg, 10kg, 12,5kg, 15kg, 7,5kg, 21kg, 4,5kg, 28kg, 1,5kg, 35kg, and 3,5kg. Below these, partial labels reading "2kg", "5kg", and "12kg" are also discernible on further plates. The weight plates are guided by a central vertical metal rod. To the immediate right of the weight stack, a black coiled spring mechanism is visible, extending vertically alongside the plates. The entire weight stack is partially obscured on both sides by two frosted, translucent grey plastic shields, which show numerous scratches and dust particles on their surfaces. The bottom portion of the image reveals a dark, speckled floor, consistent with rubber gym flooring. A curved silver-colored metallic bar and a small orange object are partially visible on the floor in the lower right corner of the frame. No individuals are present, and no actions or interactions are depicted.
