Choi Siwon is responsible for Super Junior's toned bodies?

Popular idol group Super Junior recently came back to the k-pop scene with their new album and transformed looks, causing a great interest among fans. In contrast to their usual quirky and funny selves, 10 of the Super Junior members came back with tight abs and noticeable arm muscles. They are now being referred to as "beast idols" much like idol group 2PM because of their athletic looking bodies. After releasing their fourth album from the 14th to the 16th, they have been performing their title song BONAMANA and appearing on various music shows, including KBS Music Bank, MBC Music Core, and SBS Inkigayo. On the 18th, SM Entertainment explained, "Most of the Super Junior members exercised very hard and placed a lot of effort into shaping their bodies for the upcoming album." The company then continued, "Super Junior started to exercise as a hobby because fellow member Choi Siwon had an interest in exercising for a long time." I guess the Super Junior members were either jealous of or inspired by Choi Siwon's Greek God-like body and began to take better care of their own figures as well. The results seem well worth it as ELFs all over the world are enjoying the enhanced eye candy. Additionally, Super Junior was featured on Melon Special, talking about and promoting their fourth album. The clip can be viewed below. http://www.youtube.com/watch?v=IdkszXHzbCI
