SISTAR's Soyu is known for her glamorous figure, so understandably, she has pride regarding her body.  However, she also revealed on JTBC's 'Witch Hunt' on March 27 that there were some difficulties maintaining her voluptuous bod.

She revealed that she worried her volume would disappear if she dieted, saying, "You lose fat, don't you, when you exercise?  Then I lose in both my upper and lower bodies," saying she could not maintain both her volume and her health.  

Here, Shin Dong Yup stated, "There are quite a lot of people who worry about losing the weight in their breasts when they exercise."  Soyu added, "There are probably a lot."

However, fellow label mate K.Will was also on the show this day to add some humor to this topic.  He revealed, "Before Soyu debuted, she was watching some video of a sexy female singer.  I was just standing behind her when Soyu said, 'They really don't know what glamor is.  I need to debut quickly,'" embarrassing Soyu but amusing everybody else.

The MCs asked Soyu if she had confidence in her body to which she replied, "I don't not have confidence."
