Two main ways. The cheaper (and still pretty accurate way) is with calipurs. Go to a gym or find a doctor or someone that will do this (a personal trainer at a gym almost always does this and it usually only costs 5 - 10 dollars).Quote:
How do you find out your body fat percentage anyway?!
They take a calipur out, pinch a layer of fat, and measure it. Usually they do two or three measurements and take an average. Likely spots to do this are your abdomen, back, leg, bicep, tricep, etc. The more spots you take, the more accurate. They have a chart where they look up the numbers and determine what body fat about that is.
The better way, (and more expensive) is called hydrolisis I believe. They put you on a scale, and have you expell your breath while they dunk you in water and they weigh that. That weight is almost pure body mass (since your body is made up mostly of water, dunking in water will pretty much nullify water weight). So whatever's left (whether it be 50 pounds, 30 pounds, whatever) is your muscle, fat, bones, ligaments, etc. They do some trickery and some tests, and can usually determine how much fat you have, how much of your weight is water, how much is fat, how much is muscle, and how much is "other".
