First of all, I don't work for or have any connection with Nintendo!
But I would like to suggest for people that are having trouble exercising the more obvious ways that they give the Wii a go. My children have always played on it and I found it useful when I needed to exercise but didn't want to go to the gym. Walking bores me, cycling hurts my bottom and swimming gives me tinnitus so I was kind of stuck. However, I have tried several programmes and found that the 'hard' exercise ones give me a good 1/2 hour work out where I burn about 100 calories. I then swap to a dance or gentle sport one for as long as I want or can be bothered. I do this at least 3 times a week and try for more. My fitness levels have certainly improved, as well as flexiblity. The nicest thing is that I can do it in my own time with no-one around to make me feel like I'm being judged. You do have to have the willpower to make yourself do it but I find once the routine is established I don't like missing my 'Wii' time!
