Got mine for the kids on Friday and I can honestly say its FANTASTIC!! The kids think its brilliant fun (they are aged 11 and 18) but I think it really comes into its own for me!! I am a couch potato to say the least and this is far easier for me to pull the board from under the settee,bung the disc in the Wii and do the exercises that are at most 3 mins long! OK- I can hear you all screaming "get off your bum you lazy so and so and do some exercise! and I can also hear you screaming on about the Wii Fit being an expensive waste of money when I could just work out to an exercise dvd! ( I can hear all this cus I have very good ears!!! I am a Mom after all!!)
BUT as far as I can see, £65 is cheaper than a gym membership (I have been a member of a local gym for nearly 3 years and have probably only gone 7 times in total!) and if I have the facility to exercise in the house in short bursts that dont kill me, then I am more likely to do 30 mins a day (which I have been doing). Any exercise is better than none, and in my opinion the Wii Fit is well worth the money, and the wait for delivery.
