Anyway, the reading was 22%, meaning at 193 pounts I have a "lean body mass" of 151.5 pounds, which, presumably, I can increase somewhat through continued muscle building. I think what that means is that my ultimate target weight of 165 is achievable.
I plan on doing body fat measurements once a month from here on out, just so I can measure the trend...I think it's more meaningful than what the scale says. (That, and what the scale says hasn't been changing much....yet!)
