We've still got the original Wii and use it with WiiFit and the Balance Board. Some of the games are fairly active too, they get you standing up, jigging around, stretching, and generally moving.

It's great to get feedback on things like their yoga moves, I firmly believe they are good for core strength and balance.

I appreciate it's not as rigid or intense as a gym could be, but it's very handy and fits in as and when we can. I've always been on the same opinion as another poster that "some exercise >>>>> no exercise, and also that moderate exercise >>>>> some exercise".

To put that in context, we're older, comparatively sedentary, and my wife has some medical issues with bone & muscle.
