If your using the Wii as a workout , Wii-hab , or just playing it for fun you know how sore your muscles can get the next day.  Most people of course don’t want to admit it but it definitely happens.   A TV news report is calling this soreness Wii-itis and they are recommending that you stretch before you play for a prolonged period of time.  

I’m not sure I think people have to go out of their way to stretch before playing the Wii everytime but I suppose it depends on the person.   I know I’ve felt sore playing some games, especially Wii-Tennis.   Recent reports have stated that playing the Wii will not substitute a real workout, but doing something is still better than nothing at all.  

As of today the Wii Fit release date has yet to be announced but has sold over 1 million units in Japan.
