Kids need about an hour of physical activity a day to stay healthy.
But can the Wii game system do that?
"You can't do this laying back on the couch and snacking," Quincy Gamestop manager Rob Shipman said.
The way you move your arms is the way your characters move in the game.
"I believe it's a good start. Anything that gets kids off the couch and up and moving is a start to getting them more active," Personal Trainer Dee St. Clair said.
If a gamer is driving, he has to move the controller like a steering wheel.
Sports games require much more movement like throwing a football or swinging a racket.
"That could get kids interested in playing sports and that's great," St. Clair said.
When it comes to exercise, games can be fun, but there's nothing like the real thing.
