Wii Fit is comprised of the motion sensitive balance board and the actual Wii Fit game.

You first need to set up your little character - Mii and then calculate your BMI (body mass index). This is worked out by measuring your weight and center of gravity and inputting your height.

Once your BMI is analysed you then need to do a simple balance test which will give you your Wii Fit age - a bit like in Brain Training.

There are over 40 activities which are divided into four categories - aerobics, yoga poses, muscle conditioning and balance games. Some of the games are locked until you achieve earn Fit credits. You can earn more Fit credits the more time you spend exercising.

The Wii Fit launches in the UK on 25th April - get your preorder in so as not to be disappointed with the predicted stock shortages.
