Fitness machine for child gamers

I don't see this catching on, somehow...

A machine has been invented to encourage children to work out while they are playing computer games. The Step2Play step exercise machine links directly to a child's computer games console. The game's controller will only work if the child keeps up a constant pre-set rate of exercise.

Because the system only controls the game's controller, and not the game itself, it can be used with any Playstation game. The game pauses while the controller is inactive. Two players can use different steppers and controllers to play two-player games. The machine also has a parental over-ride and is aimed at youngsters under the age of 12.
