Hii-ya

The latest add-on to join Kinect Fun Labs is fitness freebie Junk Fu, out on Xbox Live Marketplace today.

The official description is... interesting, to say the least:

Can you master Junk Fu? Or will Junk Fu master you? Chop, kick, and smash junk as it flies off a junkyard conveyor belt. Turn junk into junk food by cranking up your calorie burn! The more you move, the more you burn. The more you burn, the more goodies you earn!

You can queue up your Kinect Fun Labs: Junk Fu now.
