During the show, SISTAR revealed that women should check their lower back muscle when they wake up in the morning.
Hyorin shared, "There is a figure that women like, and there's a figure that men like. I think the back profile is important on women."
To help the viewers understand, Soyu demonstrated lifting workouts to tone up the lower back muscle. She caught the viewers' attention with her tight workout clothes and professional form. MC Kim Gu Ra commented, "The trainer in my neighborhood has the same thighs as her."
