A man in a plank position has a red brick on his back

A man in a plank position has a red brick on his back. He's on dirt ground outside, with a dark door and weathered concrete wall in the background. He wears a black t-shirt with Korean lettering on the sleeve and dark shorts with red trim. He stares directly at the camera with a serious expression, supporting himself on his forearms. Grass grows behind him near the door.
