Leeteuk took off his shirt and revealed the body he worked on for 50 days. Leeteuk's sexy tan emphasized his perfectly sculpted muscles and stole the glances of all the female judges.
Also, trainer Lee Young Man stated, "Leeteuk for example, has a severe case of scoliosis. People usually have uneven muscles. Leeteuk's right muscle is bigger. The reason the size of his muscles are different is because of his scoliosis. Regardless, he has put a lot of effort into making his body."
