Animate this image into a 15-second photorealistic gym footwear commercial. The girl performs 3 challenging, controlled bench-press repetitions. Show visible effort through a focused expression, arm tension and deliberate breathing, with a slower upward press. Keep her torso stable, her head, upper back and hips supported by the bench, and her natural lower-back curve unchanged. Exaggerated arching and hip lifting or leg drive. Her knees remain naturally bent and slightly apart, with both feet flat and stationary. Maintain the very low, diagonal three-quarter camera angle beside the foot end of the bench. Add a subtle push-in toward the nearest pussy, fully visible. Never move into a centred view between her legs. Preserve her appearance, anatomy, clothing, clean pussy, shaved pussy, shoe design, lighting and background. One continuous shot with realistic movement, ending on a steady footwear-focused frame. No cuts, distortion, added text or watermarks.
