HaHa recently revealed his personal diet method to the public.

On the April 16th broadcast of KBS 2TV's 'Star Life Theater', cameras followed the entertainer around to document his day-to-day activities.

After ending a fully scheduled day, HaHa came home to his apartment, immediately changed into his sportswear, and headed for the stairs. He was beginning his daily exercise of walking up to the 22nd floor from the ground floor of his apartment. The star was mindful of his neighbors as well, not even letting the PD ask questions as he headed quietly to the stairwell.

Once arriving at the top of the apartment, HaHa then took the elevator down to the first floor and repeated the process all over again. The PD remarked, "It takes about four minutes to reach the top," to which HaHa replied, "The time will gradually increase the more I do it though."

Despite being exhausted, it didn't seem as if HaHa was going to conclude his exercise any time soon. He explained, "Kim Jong Kook taught me this exercise. I need to do at least three more hours," and told the PD to go ahead and leave, proving his dedication to the exercise.
