Watch these rowers play tug-o-war in a pool

Need a great work-out?

Gather your friends and co-workers for a friendly battle of 'water tug-o-war'!

All you need is about twelve people, a dragon boat, and rested arms.

Two teams sit facing each other on opposite sides of the boat, and paddle the hell out of that oar to win the game.

The competition is big in Australia, Asia and eastern Europe, as seen in the video below.

Maybe one day we'll see this game in the Olympics.
