Our family is on the Wii Fit train, which just means that we found an excuse to play the Wii on school days. Basically, the Wii Fit is a plank or board that you stand on and it weighs you, tracks your BMI and basically tells you that you're either obese, overweight, normal or underweight. Warning, if you have a large TV (ours is pretty decent), in large letters, this machine will show your weight and BMI. If you're like the majority of my family, it will also tell you "that's obese!" in a cutesy, irritating, little girl voice. Not only that, but indignity upon indignity, your mii (your character on the game) will turn fat!! Once you are done yelling at the tv ( "no S&%#, you think I do know I fat?!") it encourages you to train by choosing exercises like yoga, strength, aerobics and balance "games." The only person that is normal in our family is Ahi, and lazy buggah actually figures out how to cheat so that he is the only one not breaking a sweat on the Wii Fit. Still, if you can find this game (it took us 3 months of active searching), it's fun, motivational, and a good investment for our health.
