"Create a modern, minimalist logo for a professional sports coach brand. The design should feature a strong, athletic silhouette (muscular or dynamic movement like running or lifting), combined with a sleek abstract symbol or initials. Use a bold and powerful style with clean lines, high contrast, and a premium look. Color palette: black, white, and metallic gold or silver accents. No text or slogan. The logo should feel energetic, motivating, and high-end, suitable for personal training, fitness coaching, and athletic performance. Vector style, sharp details, centered composition, dark background."
