A medium shot from a slightly low angle featuring Rinka, a tall original female character, performing barbell squats in a gym setting. Rinka is a 175cm tall woman with a voluptuous build, featuring an H-cup bust, a slender 54cm waist with subtle abdominal definition, and wide, curvy hips with thick thighs. She has long, raven-black hair extending to her thighs and messy bangs reaching her eyebrows, with sharp, upturned black eyes and a focused expression. She is dressed in tight-fitting athletic training wear that accentuates her large, firm yet soft breasts and toned physique. She is captured mid-squat, her hands firmly gripping a weighted barbell resting across her upper back. The background is a modern gym with weight racks, rubber flooring, and industrial lighting. The visual style is a high-quality anime illustration with clean lines and vibrant coloring, utilizing soft lighting to emphasize the contours of her body and a focused, athletic atmosphere.
