The Boyz's Jooyeon shared some of the energetic training he did to prepare for his first ever trip to 'Laws of the Jungle'!

First, Jooyeon brought his trustworthy The Boyz members Younghoon and Hyunjae to a forest park to get used to the feel of a "jungle". Even in the winter, The Boyz members waded into the shallow park lake to practice "scavenging".

Next, the three boys visited the site of the highest bungee jump in Korea, at 63 meters! Jooyeon smiled nervously at the top of the jump spot, but jumped without any hesitation whatsoever, cheering on The Boyz as well as 'Laws of the Jungle'. 

Finally, all three members got to experience real, rock-face rock climbing at a height of a whopping 100 meters, at a beginner's rock climbing spot in Gangwon-do. Check out Jooyeon's youthful preparations for 'Laws of the Jungle', above!
