15% is really low, unless you’re a man. 15%
body fat for a man is really good. So from your username I think you a woman, and 15%
body fat isn't really a good
goal, unless you want to be a
body builder or something. 18% is probably a better
goal. A female track runner has a
body fat from 12-20%. And get your
body fat check with a skid fold test, not on of those Bioelectrical Impedance Analysis things. they suck. Manly because the percent can change with in MINS. Say you take the test, then drink a liter of water in the next 10 min, and take the test again; you will probably get 2 different readings. So go to a
fitness center in ask to have a skin fold test done.
