Group Super Junior's Kangin fell in love with working out.

Yesterday, Kangin posted on his Twitter, "Working hard" along with a picture.

In the picture, Kangin is in a sleeveless shirt with a black hat, working out in the gym. He regained the fit body he used to have in the past.

Internet users who saw this commented, "You have to work out hard to become like him," "The good looks he gained through efforts," etc.
