"Create a 4K, hyper-realistic video set in a modern fitness center. Show the gym owner smiling and standing in a now-bustling gym with energized clients using various equipment. Capture the vibrant atmosphere: clients of different fitness levels and ages working out, a few chatting in the background, creating a lively, welcoming space. The gym owner observes the activity with a satisfied smile. Emphasize the realistic gym setting with detailed equipment, natural lighting, and warm colors. Ensure the owner’s outfit and appearance match in continuity with the next video."
