Group Big Bang's abs were revealed.

YG Entertainment's trainer Coach Hwang posted on his Facebook, "2009. One day~ Just keep going~" along with a picture.

The revealed picture was taken in 2009, and Big Bang's members Daesung, Taeyang, and Seungri are shirtless, revealing their clearly defined abs. Daesung and Taeyang are leisurely smiling, but Seungri seems nervous, arousing laughter.

Internet users who saw this commented, "Big Bang is a group with the best bodies," "Where are G-Dragon and TOP?," and "Those abs are still there, right?"
