Oh, I had absolutely no idea that YOU were the guy doing all of this! XD Ahem, I of course mean by that, congratulations. =P
That said, I think I doomed myself to failure by just doing the same thing over and over again. Mind you, this was during college so I'd do it after classes, when I was already feeling the wear of the day, and I just couldn't do it after a few days. Got too boring. When I did it again recently, I wanted to try to keep it going for 30 minutes but I barely made it to 20 since my body was literally shutting down on me. Oh did I have incredible arm pain for a while after that--a surefire sign that the only shape I'm in is round.
I really do want WiiFit beyond the whole novelty factor that I presume a good number of people are snatching it off the shelves, but it's a hefty investment in something I naturally can't try out, and finding it lately has been impossible. Being overweight as I am, I would greatly like to try it before I come to break the machine trying it, so as to actually get some use out of it. I certainly don't doubt that it works, but if I'm having fun while doing it all, I would be more likely to continue with the regime since it wouldn't seem so much like I'm doing actual work. I've heard it can work most of the body and that'd be fine enough for me.
You really are inspiring, and the notion of getting something of a workout playing a game that isn't DDR is starting to become less insane as time goes by. =P
