Lee Hyori revealed her secret behind how she maintains her perfect body.

SBS 'You & I' aired on June 10, Lee Hyori, who has been buying much attention for her revealing clothes in the show, revealed the secret to her body.

On this day, Jung Jae Hyung asked, "You wear a lot of revealing clothes. How do you maintain your body?"

Lee Hyori replied, "Of course I'm not constantly thinking about diet, but my figure is important to me because I'm a dance singer. If my fat is jiggling when I'm dancing then people watching are uncomfortable, and it's unprofessional, so I continuously take care of my body."

Jung Jae Hyung then said, "I, too, sing ballad often and play the piano, so I'm trying very hard to build my arm muscles because they show when I play the piano", arousing laughter.
