Planking originated in Australia and it has been a source of irritation for the Australian police this year. One planker was arrested for planking on top of a police car. Plankers have declared "Planking Day" for May 25, 2011, which will now be an annual event.
“悬空”源自澳大利亚，它警方带来了麻烦。一根悬空表演者因为在警车顶部悬空而被逮捕。悬空表演者们将20011年5月25日定为“悬空日”，以后将每年举办。

Most people probably have yet to hear about planking. It is actually a simple stunt, albeit goofy, that practically anyone can do. Lie face down, straight as a board, pointed toes, arms to the side with straight pointed fingers. The planker's face must remain expressionless, head held straight, not turned. Pretend as if rigor mortis has set in.
许多人可能听过说“悬空”。实际上那只是一种简单的特技，虽然愚笨，但是每个人都能做。脸朝下躺着，像木板一样平躺，脚尖伸直，胳膊放到身体一侧，手指也要伸直。悬空表演者要面无表情，头部平伸，不转动。假装身体十分僵硬。

As you can see from this photo, planking can build strong abs.
从这个照片可以看到，悬空能锻炼强有力得腹肌。
