Just watched f(x)'s performance for Chu on Inkigayo a while ago.

f(x)'s leader Victoria is well-known for her flexible body as she has learned acrobatic as well as ballet for more than 10 years if i am not mistaken.

It is usual to see Victoria flipping after Amber's rap in Chu performance,but usually she only does it once in each performance.However,she made it two on today's show!

Watch the video below to see how flexible she is!
