When asked what is the secret to her supermodel figure, Nana shared her methods, "Every night, I do 100 squats and 100 push-ups. Even though it's difficult, I make sure to do it before I go to sleep... I also walk up the stairs, two steps at a time, to maintain my pretty leg line."

Nana also chose English model Cara Delevingne and actress Kim Min Hee as the style icons who she looks up to.

Even during her group's hiatus, Nana has been busy filming SBS' 'Roommate' and working as the MC of OnStyle's 'Style Log'.
