AI Video Prompt

Create a realistic vertical 9:16 documentary-style video showing one adult male exercising inside a transparent underwater treadmill machine in a modern indoor aquatic fitness room. The man wears a black short-sleeve shirt and black shorts. He is inside a glass water chamber with metallic support rails. The water reaches around his waist level. He slowly walks forward on the underwater treadmill while holding the rails naturally. Show the transparent machine, blue-green water, reflections on glass, digital control screen, white tiled floor, curtains, and ceiling LED lights. Use realistic smartphone camera footage style. Begin with a wide exterior shot showing the complete machine, move into medium and close side views showing walking motion, water ripples, hand contact with rails, and realistic underwater resistance. Maintain the same person, same clothing, same machine, same indoor environment, same lighting, and realistic physics throughout. No additional characters, no added objects, no dialogue, no fantasy elements, no unrealistic movements.
