Prompt: Positive and upbeat digital illustration featuring an athletic young woman performing bicep curls with dumbbells in the gym. She stands tall and focused in flattering fitness clothing, muscles lightly flexed in good form, completing her set with a look of quiet determination rather than extreme intensity. Soft stadium lighting illuminates the scene - exercise equipment, a water bottle and towel place her in a comfortable training context. Composition and color palette aim more to inspire rather than overwhelm. One hand curled, gripping black neoprene dumbbell, the other on her hip in a relaxed contrapposto stance. Details bring out realism and grace rather than grit.
