A young boy with blond hair, wearing only underwear, is sitting on a white bed. He is looking directly at the camera with a slightly serious expression. Behind him, there is a wooden cabinet to the left and a poster of the human muscular system on the wall. He is stretching his arm upwards, making a fist, and bending his torso to the side. The lighting in the room is soft, and there are a few small objects on a bedside table. The scene appears to be taking place in a medical or therapy room.
