A first-person, downward perspective shows the lower body of an individual operating a "PowerMill" stair climber machine within a fitness center in Mexico City, Mexico. The subject's legs, wearing dark athletic shorts and white athletic shoes with black laces, are positioned on the machine's steps. A grey hooded sweatshirt hangs from the machine's central support. A white sticker with a red top border, displaying the number "2" and Spanish text ("USO DE LA TOALLA OBLIGATORIO DESPUÉS DE CADA INSTALACIÓN DE FITNESS. FAVOR DE LIMPIAR LA MÁQUINA DESPUÉS DE UTILIZAR TU EJERCICIO."), is affixed to the central support. A "Life Fitness" branded machine with a silver frame is partially visible to the left.
