In this ad, Nintendo says it had Wii Fit researched by Japan's National Institute of Health and Nutrition. About time! The game's only been out for over a year.

The researchers found out that doing the Wii Fit hula hoop game was the equivalent of "light walking" or playing golf without using a golf cart.

Wait, the Wii Fit hula hoop game is the equivalent of light walking? Light walking is not only considered an ideal low-impact exercise, but it's also totally free. Last we checked, Wii Fit is not free.

Good thing Nintendo's Shigeru Miyamoto already said Wii Fit's purpose is to make you fit. Oh wait.
