The trainer also giggled while joking that Jessica suddenly shouts if the workout becomes too difficult. It was also revealed that KARA's Hara completes�100 to 300 moves for one set to maintain her 'ant waist'.

Suzy's trainer shared, "Young girl groups are most tempted by flour based foods including spicy rice cakes (ddukbbokki), kim bap, and soondae.�If Suzy sees me eating by myself, she says 'How can the teacher eat by himself' and gets antsy. I can't get myself to look at her glaring eyes [when I eat]."
