Well, there is only one thing I know, and that is to ask them!
These Girls' are known for their beautiful legs and "S" shape body. Simple yet maintained exercise can keep the girls fit and stay in shape.
I found this photo over the Internet where the body measurements of the girls are revealed. I don't know if it is true.
From left it's Tiffany then Sunny, Taeyeon, Yuri, Yoona, Seohyun, Jessica, Hyoyeon, and Sooyoung.
Tiffany, Sunny, Yuri, and Jessica will teach us some practical tricks on how to achieve the ideal figure for the body.
