Not sure if you are aware, but Wii jog is a small device that connects between the nunchuck & remote. It stops any movement on screen until you start walking / jogging. The unit also measures how many steps u have done and calculates the kcal burnt. I notice you can now buy for around £3 new. (Think I paid nearly £20 when they first came out.) I think this only works on games that need both nunchuck & remote.
