Create a modern, sleek cover image for a fitness tracking mobile app. The design should include a smartphone mockup displaying the app UI, surrounded by abstract fitness-related elements like heart rate icons, steps, dumbbells, and gradient waves. Use a clean layout with bold typography that says 'FitTrack – Your Personal Fitness Companion'. Color scheme should be energetic and vibrant (e.g., blue, green, and white). Make it minimal yet engaging, suitable as a portfolio or presentation cover."
