F(x)'s Krystal Jung recently showed us some leg; now she's showing us how to get those legs. In the December Vogue Girl, the K-Pop goddess and actress teams up with Adidas for Women to show people how working out is done.

Everybody knows about Krystal's incredible music career, but lately her acting accomplishments have been just as prolific.She appeared in the popular TV show High Kick! and of course as Lee Bo Na in Heirs. In her December photo shoot, Jung sports tight and athletic workout clothes that showcase her fit physique. Check out the fun and energetic pics as Krystal continues to amaze!

Looking tough and ready!

Krystal's probably thinking, "I can lift this with my mind." She is wearing an Adidas hoodie and leggings.
