Silhouetted Treadmills in Glass Gym at Blue Hour

Cool blue twilight fills the space behind floor-to-ceiling glass walls, casting the gym interior into deep shadow. A row of treadmill consoles stands silhouetted against the fading light, their blinking LED displays offering the only sharp points of color in the dim room. The wet, dark surface of the adjacent lap pool reflects the sky's indigo hue, stretching toward the glass barrier. Warm interior shadows pool on the rubberized flooring near the equipment, against the cold exterior glow. The consoles appear motionless, waiting for the morning session, while the glass panes faintly mirror the empty deck outside. One red light blinks rhythmically on the nearest console panel.
