The other common method is bioelectric impedence; this is a machine that looks like a scale tanita and health and is common in many gyms and even available for home use. This can be a very unreliable measure, as it is highly dependent on water weight, temperature, electrolytes, blood flow, and other factors. Bioelectric impedence is even less accurate in athletes with a large amount of muscle. All these measurements are interesting and can suggest health, tanita and health but should not tanita and health be the basis of an exercise or nutrition regime. Remember, if you are using weight as your guide, that muscle weighs more than fat. If you are increasing strength but not changing your weight, you are becoming leaner. The following are loose guidelines for healthy weights in athletic women. |

The most accurate measurement is through DEXA, an expensive measurement done in a radiology lab or doctor's office; this is the same radiographic measurement used to determine bone density. The second most accurate method is water displacement, although this requires your body to be underwater in a special tank, even more impractical and expensive. One of the simplest, most common measures of body fat percentile measurement is skinfold measurements, in which a tester uses calipers to measure fat pinches at various sites on the body. |
