Heavy-duty metal racks hold sleek, chrome weights that gleam under the ambient glow. Retro-futuristic cardio machines have glowing screens with sci-fi graphics. A wall-mounted smart panel displays personalized workout metrics in holographic font. The air is filled with the hum of machines and the faint scent of ozone.
