On February 1st, Subin uploaded a picture of herself as well as the caption, "I've finally finished shooting for 'Muscle Queen Project' and completed my hectic schedule."

Her company, Happy Face Entertainment, stated that "Soobin started training diligently 3 weeks prior to the shoot. She made time in between her busy schedules and went as far as to workout into the late hours of the night. She would often sleep less and opt to workout during that time. We ask that everyone looks on her efforts favorably."

'Muscle Queen Project' will follow 7 physical trainers and 7 female celebrities on a quest to challenge themselves in a wide array of different tasks.
