The video shows a close-up of a person's legs as they run on a treadmill. The person is wearing orange and white sneakers and the treadmill is moving at a steady pace. The camera angle is low and close to the ground, focusing on the person's legs and feet as they move. The treadmill belt moves continuously, and the person's legs move in a steady rhythm. The background is blurred, but it appears to be an indoor setting, possibly a gym or fitness center.
