The video shows a man performing sit-ups on a blue mat in a room. He is wearing light grey sweatpants and is shirtless. The room has a blackboard with writing on it, and there are various items in the background, including a desk with a computer and a shelf with bottles. The man starts by lying on his back, then lifts his upper body towards his knees, and finally returns to the starting position. He repeats this motion several times.
