Rosario Dawson Is Planking Again, This Time on 'Chelsea Lately' (VIDEO)

Rosario Dawson has a new obsession, and she's more than ready to show it on national television. She already gave a demonstration on 'Jimmy Kimmel Live,' but for her first-ever appearance on 'Chelsea Lately' (Weeknights, 11PM ET on E!), she upped the ante.

She thought it was a big deal to plank on the back of an elephant, but we found her demonstration on the 'Chelsea' set far more impressive. It's one thing to lay flat on your face on a flat surface with full support beneath your body, as she did on the elephant and on Kimmel's desk.

It's quite another to plank while being supported only by the arms of a chair, as she did for Chelsea Handler. That looks like it takes concentration and quite a bit of muscle strength to keep your body straight like that.

It's still a rather bizarre hobby, but one that Dawson is clearly excited about. Could the world planking championships be in her future, or even a movie role that somehow features this strange ability?
