A scantily clad Gunnar Nelson dances to "Chandelier"

Martial art champion Gunnar Nelson showed a rather different side to himself in a video he made with fellow martial arts practioners at the Mjölnir martial arts centre in Reykjavík. The video was made for a Mjölnir celebration and shows Nelsson dancing to Sia's hit Chandelier. 

Dancing along with Nelson are Árni Ísaks­son, Þráinn Kolbeinsson and Henning Jónasson. Watch the video below.
