A person is running on a treadmill in a gym. The runner is wearing a blue t-shirt, light-colored trousers, and sandals. The treadmill is black and silver, with a digital display. In the background, a mirror reflects the runner and other people in the gym, some of whom are exercising. A barbell with weights rests on the floor to the right of the treadmill. The floor is covered in green turf. The wall is painted a light green color with a blue accent.
