Wii Sports, My Excuse for Not Exercising

Well, I guess I haven't been posting as much as I would like. It's hard to get back into the habit. T0day my excuse is that I have been playing Wii Sports since I got home from work (minus time for dinner). I couldn't tear myself away! For one thing, I've been playing amazing today. As I sit sweat-drenched in this chair with my right arm aching, I am still ready to get back to it after I write here.
Like I said, I was friggin' amazing today. When I got home, I played a game of baseball. Now, I hardly ever play baseball. My game is boxing, personally. But today, I scored 7 runs in the first inning and pitched a no-hitter. It was a mercy rule. I went up over one hundred points! Then I played tennis. I played a 3 out of 5 match and won all 3 of the first games. Two were won with the other team only scoring once! I rock.
If you don't have a Wii and are reading this, you're probably thinking unfriendly thoughts along the lines of "pathetic loser" and such, but you cannot understand the power of a Wii unless you are one of the privileged few to own one. The very best reason to own a Wii, though, is not its addictive gameplay or innovative controls. No, the power of the Wii lies in its incredible power to be an excuse to not exercise.
Allow me to elaborate. Ever since I moved out on my own, I have gained a large amount of weight. I blame a couple things:

1. Job Switch - I went from being a teacher where I was up and actively teaching for hours everyday and helping out in the child care to sitting on my increasingly large buttocks for nine hours everyday.
2. Diet Change - When I lived with my parents, I was fed a large array of home cooked food. During my time living by myself, I mostly ate things that were cooked by microwaves rather than actual heat.
3. Increased Eating Between Meals - My work provides me with unlimited goodies during the day. I could not help but partake in more than my fair share.

Thus, my body shape went from, well not slim, but healthy to a far more rotund shape.
To thwart my increasing mass, I have vowed to exercise more and eat less. I have been doing fine in the eating less field, cutting way down on in between meal snacks and being more conscientious about what I eat. The exercise, though, has been elusive. This is where the Wii has proved itself very useful.
One does work up quite a sweat from playing the Wii, certainly, but I hesitate to call it real exercise. It does not work one's lower body at all and there is no resistance to the movement required of the activities. Yet, I still use it as an excuse. For example, when my wife asks when I am going to join the gym (I have been meaning to, really), I simply ask her "Gym?! Who needs a gym when we've got a Wii?!" In my mind, I am burning more calories than a beaver in an espresso lake when I play the Wii. I can actually feel the pounds peeling off me. And I know that it is all psychosomatic.
It's even worse now because we have bought more games for the Wii. When I am playing Call of Duty 3, I am sitting down. The most action I get is reloading my weapon, which takes a quick upward jerk of the wrist. Wario Ware: Smooth Moves is a little better, but not nearly enough to be meaningful exercise.
Yet I continue my self-delusion because deep in my heart, I want to believe that exercise can be this easy. *Sigh*
