A young man flexes his right arm while facing away from the camera

A young man flexes his right arm while facing away from the camera. His back is bare, showing muscle definition. He is wearing dark pants with a glimpse of grey underwear at the waistband. His left hand rests on his hip. The scene is in a locker room with rows of lockers, some red and some white. A phone is visible in the lower-left corner, suggesting a selfie. Another person is reflected in the mirror.
