He revealed his sculpted body, which he worked on for 50 days with trainer Lee Young Man, for theshow’s ‘Buff King‘ contest. The trainer commented, “He hasn’t even been able to go on a honeymoon because of training. Even on the day of his wedding, we trained after it ended,” referring to Leeteuk’s on-screen marriage to Kang Sora on ‘We Got Married‘.
He added, “In Leeteuk’s case, his scoliosis is severe.” Leeteuk explained that his back has been bent ever since he was in a car accident.
Lee Young Man went on, “People usually have asymmetrical chests, and Leeteuk’s right muscle is bigger than his left. His muscles have become crooked because of scoliosis, but he really tried his best.”
