What may finally be the best of all worlds, the InBody
is a machine that combines the ease-of-use of a BIA device with the accuracy of hydrostatic weighing. In testing the InBody correlated with the hydrostatic results with 98 percent agreement.
The process involves standing on a metal platform and holding onto two handles for about one minute. In addition to your body fat percentage, the InBody can tell you where your fat is stored and where you have water collecting in your body (edema), which can be a sign of injury or inflammation. It will also measure your RMR, BMR, and relative strength of each of your limbs.
The machines are expensive but taking the test usually isn't. The InBody is fairly new technology so it can be hard to find, but most Lifetime Fitness gyms have the service available to members and non-members alike. When it comes to ease of use and accuracy, it may be worth the effort to find one near you!
