Work and me

A man in a black shirt and grey pants repeatedly lifts and drops a large, brown, sack-like object onto the back of a person lying on the floor in a living room. The man swings the object down in a rhythmic, downward motion, then lifts it back up, repeating the action. The person on the floor remains motionless throughout the sequence. The setting is a living room with a grey carpet, wooden furniture, and a television displaying a blue screen.
