Recently on an online community board, various pictures of Wonder Girls’ member Yoobin were uploaded and compared with respect to her weight change. Below are two photos of the Wonder Girls at the recent concert in Malaysia.

It appears that Yoobin is now the skinniest girl among all the Wonder Girls’ members. It is rumored that when her weight was at its peak, she did countless numbers of jump ropes on a regular basis to lose weight.

Based on these pictures, we can be sure that she is definitely great at pulling off successful diet plans.

Meanwhile, Wonder Girls recently became one of the chosen four bands to participate in MTV Iggy’s “Cover the World” project. They are planning to tackle Cyndi Lauper’s “True Colors.”
