Singer Lee Hyori revealed herself doing a difficult yoga pose.

On August 4, Lee Hyori posted on her blog, "I tried the Ashtanga Maisol for the first time by myself. I'm still confused about the order but I was happy that I was able to do it by myself instead of following a teacher in a class" along with several photos.

In the picture, Lee Hyori opened her legs wide and put her head on the ground. Even though this is a difficult pose in yoga, she seemed calm.

She also said, "It's been almost 8 months since I've been training everyday. I heard it takes 3 years to finish primary so I want to be persistent without getting lazy. Have I ever done anything until the end? Fighting to me!"

Internet users who saw this commented, "The secret to Lee Hyori's body was yoga," "Teach me too," and "3 years? That sounds so hard."
