anime illustration, great quality, best quality, A full-body shot from a three-quarter angle shows a single young woman with long, messy red-black hair featuring blue streaks, an ahoge, and bangs partially covering her face. She wears red-framed glasses over red eyes and has her hair tied back, with side strands falling forward over her bare left shoulder. Her outfit consists of a white shirt over a black camisole, both soaked in sweat and clinging to her torso, paired with short black shorts. She is kneeling on a long black yoga mat in the center of an indoor room, gripping the handles of an ab wheel roller with both hands as she struggles through an exercise. Her face is contorted in intense concentration, cheeks puffed out. Behind her, a mesh chair sits in front of blackout curtains, while a desk with a computer monitor is visible above. The floor includes a central rug beneath the yoga mat, and the background is softly blurred.
