If you have a Twitter account, chances are you’ve recently seen tweets referring to “planking”. Planking is actually a core strengthening exercise. Down in Australia, they’ve put a spin to it by lying face down on random spots. The more absurd the better. In May, a man killed himself by planking on a balcony.

Slim Thug, rapper and planking expert, called Green Lantern’s Invasion Radio last night to explain the phenomenon. Check out some photos after the jump. Plank us later.
