Nice Try

I'd like to know who actually thought this might be the case?

What a bummer! A study by the British Medical Journal reveals that although the Wii game console offers more activity than passive videogames, Wii tennis is not an exercise substitute for real tennis.

A standard videogame only requires players ;move their thumbs and index fingers playing a standard video game, whereas the Wii actually requires players to move their hand or occasionally their entire arm to interact with the game, but that's not enough action to break a sweat for most couch potatoes.
