2. Air Displacement Plethysmography
ADP, or air displacement plethysmography, measures lean vs. fat body mass using air displacement technology. According research from the National Institutes of Health, ADP offers an expensive yet rather accurate body weight calculation.
The coolest thing about an ADP measurement is the Bod Pod, an egg-shaped dome that you sit inside while air displacement plethysmography is used to calculate your muscle vs. fat mass.
