2AM lead vocal Chang Min revealed his personal reason on why he continues to diet even after losing 30 kg.

On March 23rd broadcast of KBS 'Star Life Theatre' Chang Min visited the gym that he has been going for the past four years.

His trainer at the gym commented, "Chang Min's nickname is grandpa. If he has a schedule at 7 he comes out at 6, and if he has a schedule at 6 he comes out at 5. His morning always begins with exercise. He works out even harder than trainers.”

Chang Min who has always maintained a chubby figure once weighted over 100kgs and while preparing to become a member of 2AM, he lost 30 kg. Because losing weight was so difficult for him, he still continues to pay attention to what he's eating.

Chang Min commented "I hated the look people gave me when I was fat. It was embarrassing, I wasn't confident in myself and I kept trying to hide myself." Because he is afraid to lose his healthy body, his confidence, he still exercises every day.

He added "My mom tells me 'determined.’ She had never seen her son at 60kgs before. I am a singer and my job is to show myself. Stage is not just about singing. There is a reason why I dance, wear nice clothes, and put on glasses. As a singer I believe you need to be someone who others would want to be serenaded by. If I thought singing was all there was to it, I would have never become a member of 2AM.”
