The “trident" abs of Girls’ Generation’s Yuri are so hot. Netizens say it’s very hard to build up those “trident abs,” and having those muscles make Yuri more beautiful. In the past, Yuri’s trainer said that Yuri repeats an exercise move 600 times a day. Whatever it is, 600 times a day is a lot of work. We believe Yuri deserves what she has now.
