On the 16th, TWICE member Jeongyeon posted photos on her SNS showing her night running along the Han River. In the images wearing an all-black workout outfit with a headband and goggles, Jeongyeon displayed a noticeably slimmer silhouette. Particularly striking in the photos wearing leggings was her toned back without any excess fat, sharpened jawline, and slender arm definition, along with her firm hip and muscular thighs that showcased impressive physique and health. This reveals Jeongyeon's rigorous self-management. In 2020, Jeongyeon experienced Cushing's syndrome and rapid weight gain due to steroid side effects during treatment for a cervical disc herniation. She subsequently suspended activities multiple times due to panic and anxiety disorder symptoms. Recently recovered in health, Jeongyeon has returned to fans with a new appearance and continues to receive their support and attention.
