JYJ's Kim Jaejoong's Intense Martial Arts Training, "The Sunburnt Hands"

JYJ's Kim Jaejoong showed his sun burnt hands as a result of several hours of martial arts training under the sun.

The actor posted on his Twitter, "Can only the hands from rest of the body get sun burnt?" along with a picture of his sunburnt red hands.

His hard earned skills can be seen in the recent episode of MBC's "Time Slip Dr. Jin."

Fans showed concerns, "You should put sunblock on your hands too! Don't destroy your soft skin!" and admiration, "His veins are so manly," and "You looked amazing in the episode today!"
