A young boy, dressed in blue shorts and a patterned t-shirt, is performing sit-ups on a colorful playmat with a road and city design. He is lying on his back on the mat, with his hands placed behind his head. He then sits up fully, bringing his torso towards his legs, before returning to the starting position. The activity takes place indoors, on a light-colored wooden floor, likely in a home setting in Votkinsk, Russia. The room is brightly lit, and the boy appears focused on his exercise. No visible text is present in the video.
