TWICE member Jeongyeon posted several photos on her SNS on the 16th showing her night running along the Han River. Dressed in all-black athletic wear with a headband and goggles, she displayed a sporty appeal. What caught attention was her lean physique with no excess body fat, toned hips, and well-defined thigh muscles, suggesting rigorous personal management. In photos wearing leggings, her sharper jawline and slender forearms were particularly noticeable, showcasing her healthy fitness. Previously, Jeongyeon experienced Cushing's syndrome and rapid weight gain due to steroid side effects while undergoing cervical disc treatment in 2020. She later suspended activities multiple times due to panic and anxiety symptoms but has recently recovered her health and returned to fans.
