We got a Wii Fit today. Everything is more fun when your tv tells you to do it. Also, your Mii avatar expands around the middle if you're overweight (which I am) -- but it wouldn't do you all that much good if were actually muscular. BMI doesn't take that into account.

Anyway, it's fun. And I'm actually a little sore. I want to use this to help me do other thinkgs besides walking, which I do most days. Like yoga. That, they have.
