i'm made of 22.1% fat - and while that is about average for men my age, i find it highly unacceptable now - i weigh 187lbs and so 22% of that is 41lbs of fat i'm carrying around, that's about what a sack of dog food weighs. apparently, male professional athletes range from 6 to 13% and 14 to 18% is considered "fit" - 19 to 25% is "acceptable" and  25 to 30% is "overweight" - once you get over 30% you are obese - and over 40% means morbidly so. and so i think i'm shooting for a fat athlete body at 13% or so.
