Super Junior's Leeteuk put his bicep muscles to work.

On the March 3rd episode of SBS 'Star King', the program revealed a long parallel set of ropes that can be climbed by using only your arm strength.

The 64-year old contestant on the show swiftly climbed the rope 8-meters high using only his arms, and MC Leeteuk challenged himself to climb the rope as well.

Much to the surprise of everyone on set, Leeteuk unexpectedly climbed the rope with ease and the audience members' jaws dropped in disbelief.

Upon seeing this, Leeteuk's co-MC and close 'hyung' Boom who had a new level of respect for Leeteuk got on his knees and cried, "hyung-nim," causing everyone on set to break out in hearty laughter.

Check out Leeteuk's moves below!
