Hydrostatic Body Fat Test

Hydrostatic body fat test is the most accurate method that uses a natural process.

It's Just You And The Water

Our process is not only the most natural way to test your body fat and understand your body composition, but is also one of the most accurate ways to do so.

Why Measure Body Fat

Weight alone is not a clear indicator of good health because it does not distinguish between pounds that come from body fat and those that come from lean body mass or muscle.

What It Is

Underwater weighing is the most widely used test of body density and in the past was the criterion measure for other indirect measures.


Hydrostatic weighing is an incredibly accurate technique for measuring body composition. The technique uses tried and true variables that feature a low percentage of error. For that reason, many experts refer to hydrostatic weighing as the gold standard for measuring body composition.

Body Fat Test Process

Our Hydrostatic water-based process is for everyone.

Step One

Initial Information

We will have an initial consultation where we take down your name, age, height, and dry weight before we begin the water body fat test.

Step Two

Step Into Tank

For this step, you will need to wear a bathing suit and enter the tank in order to be tested.

Step Three

Water Body Fat Test - Exhale & Submerge

You will exhale all oxygen and completely submerge under water to be weighed. This process is repeated at least two times to get the most accurate results. The water is chlorinated, filtered, and heated between 90 and 95 degrees Farenheit.

Step Four

Get Results

You will be provided a four-page print out with your body fat percentage, lean body mass, weight, and weight in fat. In addition you will receive your resting metabolic rate as well as calories burned during different cardio exercises for your body specifically.
