And may I just say... the wii Fit is awesome! We are having so much fun with it!
When I calibrated my mii (a little cartoon person representing me on-screen) at the outset, it gave me a choice of several faces, and I chose one with short brown hair. DS7 said, "Oh yeah, Mama, that one looks the most like you." Then when I gave my height and stepped on the foot console, my BMI scale went from Underweight to Normal to Overweight to Obese, and my little mii plumped up like a balloon! I thought DS7 was going to pee his pants laughing so hard!
I said, "Well, I guess my mii looks a bit more like the real me now, huh?"
So far I've done a little yoga, ski jumping, table rolling, head-butting soccer balls, and a short run.
DS7 did two short runs and a long run and was barely winded. He was scored as a beginner runner and earned 22 points and one star for each. I, who ran much slower and thought I was going to DIE at the end (it's like a two minute run, for pete's sake!

) scored 123 points and the maximum stars, I forget if it's 4 or 5.
DS was most disappointed, but I reminded him of my age and lack of fitness, as I'm sure that's why I scored so high.
