Design a magnificent 1980s aerobics instructor in black and white, wearing a high-cut leotard with leg warmers bunched at her ankles and a sweatband around her feathered hair. She's in an energetic workout pose doing a high kick with arms flexed showing muscles. Her hair is big and teased with lots of volume and layers, typical 80s style. Expression is intense and motivating with a confident smile. The art style should have bold outlines with dynamic action lines showing movement and energy. Add geometric shapes, lightning bolt patterns, and grid backgrounds typical of 80s design. Include boombox elements, cassette tapes, and neon-inspired line effects.
