I don’t think you are measuring what you think you are.
OK, so it doesn’t take a genius to figure out that the Wii Fit Balance Board is great at measuring balance, and whether someone is putting weight on it (including whether they are on one foot or two), but not so hot at judging what the body of the exerciser looks like at any given moment.
And so it declared me a bodybuilder twice today, when I know damn well my form didn’t resemble the one on the screen.
And I don’t understand why the Wii Fit thinks that I ought to do a body test every freaking day, even if I don’t have time for exercise–it seems to me that exercising a little every day even if I don’t have time to watch it calculate my Wii Fit Age (today, just one year older than reality) or nag me about my BMI meaning that I’m obese.
But if I use it for a few strength training exercises every day, and do some aerobic exercise (not necessarily involving the wii), I ought to improve my general level of fitness.
