The woman begins exactly in the shoulder-stretch position shown in the reference image. Preserve her exact facial identity, facial features, body proportions, body softness, skin tone, denim-blue high ponytail, light-blue sports top, black leggings and overall appearance throughout the entire video. She slowly releases the shoulder stretch and naturally lowers both arms. She briefly stands relaxed and upright. She then takes one small step forward with one foot. The heel of the front foot stays on the ground while the toes lift slightly upward. Both feet remain safely on the ground. She gently shifts her hips slightly backward and makes only a small forward hinge from the hips to create a relaxed standing hamstring stretch. The movement is subtle and comfortable, not deep or athletic. Her hands naturally rest lightly on the upper thigh of the supporting leg. She does not reach toward the floor or her foot. Her upper body remains mostly upright and her head stays stable. She looks focused and naturally gazes just past the camera throughout the entire clip, without direct eye contact or posing. Her body must remain exactly as soft and feminine as in the starting reference frame. Do not increase muscle mass or muscle definition. Do not make her more athletic, leaner or more muscular. Keep the exact same shoulder width, arm size, waist, abdomen, hips and thighs from the starting frame. Her abdomen remains naturally soft with only the same subtle definition visible in the reference. Once she reaches the gentle hamstring stretch, she calmly holds the position for the remainder of the video with subtle breathing and tiny natural balance adjustments. Preserve the exact same outdoor location, lighting, framing and camera position. Fixed camera, no zoom. Only very subtle natural movement in her ponytail from the breeze. No facial morphing, no identity change, no defined abs, no muscular arms or shoulders, no increased muscle tone, no enlarged thighs, no body transformation, no deep forward bend, no leg deformation, no extra limbs or fingers, no sudden movements. Photorealistic, relaxed, feminine, subtle and natural stretching routine.
