Create a vibrant gym poster featuring a close-up portrait of a young woman performing a squat with determination. She is wearing bright, form-fitting workout gear that reflects her energy. The background is a blurred gym setting, showcasing weights and exercise mats, enhancing the focus on her. The lighting is bright and natural, casting soft shadows that highlight her muscles and form. The expression on her face conveys motivation and focus, embodying the spirit of a beginner pushing through challenges. Overlay the image with an inspiring quote in bold, modern typography at the top: "Every rep counts!" The color scheme should be energetic, with pops of neon colors to evoke enthusiasm and drive.
