An indoor martial arts training facility in Pernik, Bulgaria, is depicted. In the foreground, a skin-toned Century Body Opponent Bag (BOB) punching dummy, marked with "CENTURY" on its lower back and several square inserts on its upper back, stands mounted on a black, weighted base, facing away from the viewer. The floor is covered with interlocking blue and red foam mats. In the midground, a child wearing a white gi with an orange belt stands barefoot on the blue mat, facing away from the viewer with their left arm raised. To their right, another child, wearing a red long-sleeved shirt and dark pants, is seated on the blue mat with their back to the viewer, appearing to lean against the pale yellow wall. The room features a white ceiling with multiple rectangular fluorescent light fixtures. The pale yellow walls contain two white doors with dark handles on the right, above which a horizontal vent is visible. A banner or flag with blue, red, and white colors is partially visible further to the right. On the left wall, a large mirror reflects a partial view of another individual, possibly a child in a dark top, and a portion of another dummy or equipment. Above the mirror, a flat-screen television and a circular industrial fan are mounted.
