eBook Cover Design for 'Infinity Motion: Fuel Your Strength, Find Your Flow'

create a vibrant and dynamic cover for a fitness eBook titled Infinity Motion: Fuel Your Strength, Find Your Flow. The design should feature light, uplifting colors like soft blues, gentle pastels, and bright whites to convey energy, positivity, and a fresh start. At the center, include a subtle infinity symbol with motion lines that imply movement and flow, symbolizing an ongoing fitness journey. Add silhouettes of people in various active poses—running, stretching, and lifting weights—to represent a blend of strength, flexibility, and endurance. The background can have abstract waves or soft geometric shapes to add depth without overwhelming the main elements. Include the title in a clean, modern font with a slightly bold style, and the subtitle in a softer, flowing script to convey harmony and resilience
