Rener Gracie’s first-ever Korean Super Seminar in Seoul was a huge success with approximately 100 participants attending four seminars (8 hours total) in a single day! Among the seminar participants was none other than the Korean Zombie, Chan Sung Jung.

After the seminar, he and Rener had a great roll, which Rener narrates for your educational/viewing pleasure.

Chan Sung Jung is a South Korean mixed martial artist and kickboxer currently competing in the UFC’s Featherweight division. A professional competitor since 2007, Jung has also formerly competed for the WEC, Pancrase, World Victory Road, and DEEP.

His nickname, “The Korean Zombie” comes from his ability to continue to move forward and fight aggressively, even after taking heavy blows. Jung is currently serving in the Republic of Korea Armed Forces and thus is not ranked by most MMA media outlets, however he was ranked as #8 in official UFC Featherweight rankings before hand.

He is a purple belt in BJJ. In his rematch with Leonard Garcia on March 26, 2011 at UFC Fight Night 24, after Jung stepped in to replace an injured Nam Phan, Jung was able to avenge the original loss after submitting Garcia with a twister in the final second of the second round. This was the first time in the history of the UFC that a twister submission ended a bout and the win earned Jung his first Submission of the Night honors. This was later awarded for the Submission of the Year by the World MMA Awards. In his post-fight interview, Jung stated he learned the move by watching Eddie Bravo videos on YouTube.
