The video begins with a view of the interior of a space station, with a large circular window in the center. The walls are lined with various pieces of equipment and wires. The camera then pans to show a person wearing a blue shirt and shorts, with a harness around their waist. The person is standing on a treadmill, moving their legs in a running motion. The space station is well-lit, and the Earth can be seen through the window in the background.
