There is also a test named Hydrostatic of Underwater weighing. It is based on the fact that fat and muscle have different physical density with lean muscle mass the same volume of fat being much lighter than that of muscle. Immersing the body into the water (head is being left above the surface, but lean muscle mass then it usually doesn't have too much of fat), it is possible quite accurately measure the overage body density and thus body lean muscle mass fat content. The disadvantage is that the lung volume can contribute rather significantly to the total body volume, and the lungs inflate if a person is under a considerable stress. Imagine what happens if the person being tested is a hydrophobic or is hyperventilating: he or she will respirate excessively, with all the gasped air measured as the fat volume. One of the newest method on the market is probably the Near-Infrared Light Technology.

All the machine of this type have inbuilt software that adjusts the only parameter measured depending on many other parameters that are just being a side: age, gender, ethnicity, physical activity dtc level. etc. I toyed around with this software myself and was amused having my fat percentage magically decreased as a result of cheating with my athletic level. Another method, a good old one, is a so called dtc skin fold measurement. You purchase a skin fold caliper (it's usually very inexpensive) and pinch your skin along with under-skin fat dtc in several (7 to 20) designated areas, then produce a simple calculation as your caliper manual instructs. Why so many pinches? Because one can store his or her fat in quite different places: as you surely noticed, there are people having a tine waistline and broad hips, or that are heavy in the bottom and slim in the shoulders, and so on. By the way, the very fat distribution can tell about this particular person's health risks (you've heard of course of "apples and pears"), but this is another story.
