Ya man I agree. 21% is pretty high for what your pics looked like. Is this one of those electronic measurement things? I don't trust anything but the good old caliper test.

Yep. I wish it wasn't so damn accurate.

Incline bench - 165X3, 185X2, 195X1, 205X1
Dips - 3X5 + 60lbs
OH press contraption - doubles with what felt like 130, 160, and 160

The most I've ever pressed on incline bench is 10lbs less than my 1RM on flat bench. Kind of weird.

DEXA (Dual Energy X-ray Absorptiometry) - A relatively new technology that is very accurate and precise, DEXA is based on a three-compartment model that divides the body into total body mineral, fat-free soft (lean) mass, and fat tissue mass. This technique is based on the assumption that bone mineral content is directly proportional to the amount of photon energy absorbed by the bone being studied.

DEXA uses a whole body scanner that has two low dose x-rays at different sources that read bone and soft tissue mass simultaneously. The sources are mounted beneath a table with a detector overhead. The scanner passes across a person's reclining body with data collected at 0.5 cm intervals. A scan takes between 10-20 minutes. It is safe and noninvasive with little burden to the individual, although a person must lie still throughout the procedure.

DEXA is fast becoming the new "gold standard" because it provides a higher degree of precision in only one measurement and has the ability to show exactly where fat is distributed throughout the body. It is very reliable and its results extremely repeatable; in addition, the method is safe and presents little burden to the subject. Although this method is not as accurate in measuring the extremely obese and the cost of equipment is high, DEXA is quickly moving from the laboratory setting into clinical studies.

The DEXA looks like this:


That's a fairly decent explanation. I just got a scanner this week. I'll scan my printout/results and post it later today.

Yep. I registered at 21.7% both times. I wish it could give a breakdown between visceral and adipose fat tissue.

Adipose-
In histology, adipose tissue or fat is loose connective tissue composed of adipocytes. Adipose tissue is derived from lipoblasts. Its main role is to store energy in the form of fat, although it also cushions and insulates the body. Obesity or being overweight in humans and most animals does not depend on body weight but on the amount of body fat—specifically, adipose tissue. Two types of adipose tissue exist: white adipose tissue (WAT) and brown adipose tissue (BAT). Adipose tissue also serves as an important endocrine organ[1] by producing hormones such as leptin, resistin and the cytokine TNFα. The formation of adipose tissue appears to be controlled by the adipose gene.

Visceral-
Visceral fat, also known as organ fat or intra-abdominal fat, is located inside the peritoneal cavity, packed in between internal organs, as opposed to subcutaneous fat which is found underneath the skin and intramuscular fat which is found interspersed in skeletal muscle. An excess of visceral fat leads to the "pot belly" or "beer belly" effect, in which the abdomen protrudes excessively. This body type is also known as "apple" shaped, as opposed to "pear" shape, in which fat is deposited on the hips and buttocks. Visceral fat is composed of several adipose depots including mesenteric, epididymal white adipose tissue (EWAT) and perirenal depots. Visceral fat accumulation is associated with insulin resistance, glucose intolerance, dyslipidemia, hypertension, and coronary artery disease.

A lot of sumo wrestlers obviously have very high amounts of adipose fat tissue. Interestingly, they often have low visceral fat which typically causes the most health problems. You know that really skinny guy that always eats whatever he wants and never puts on much visible fat? Well, he might be storing a lot of it as visceral fat which increases the risk of the above mentioned medical problems. It's hard to tell.
