Wii Fit is mad fun.
Indeed. I find the non-timed runs to be more fun than the timed ones (watching TV while running in place just seems odd, whereas I can watch my Mii run a set course around the island no problem), and I have yet to try the yoga (my balance is for shit), but it's just engrossing.

And I know about the gym memberships with some insurances, which I'm all for. small steps.
