Choi Jin Hyuk shows that looking good for the camera is not as easy as everyone thinks.

During the press conference of his upcoming movie "God's Trick" on the 25th, he said, "Jung Woo Sung has a naturally fit body, which makes it seem like he has the hobby of exercising and eating healthily. It's admirable, because compared to him, I gain weight fast, and even when I try to shed some weight, it doesn't show."

He also confessed, "This is why when I have a scene that requires me to reveal my body, I try to shape it by not drinking water a week prior to the scene. When I do this, my body really shows the results."

"In the case of 'God's Trick,' we filmed at the same time with 'The Heirs,' and because we had to do well because the filming date is close to the broadcast date, I couldn't skip on a meal, and I wasn't able to prepare much for my scenes," he added.

"For the action scene, I tried to prepare by starving myself for three days prior to the filming date. I know that Jung Woo Sung is known for having a nice body, but it stressed be out that it's better than I originally thought," he concluded.

"God's Trick" is scheduled to premiere on July 3.
