What is Hydrostatic Testing?

Hydrostatic testing is a method of body composition analysis that uses Archimedes Priniciple of Displacement to determine a person’s body fat and lean body mass. It is considered the "gold standard" of all body composition assessment methods.

Northern California Body Fat Test Subject In The Tank

What is Testing Like?

Change into your swimsuit in one of our private dressing rooms (or come wearing your suit)
Record your dry weight on the scale
Get in the heated water tank (88°F - 92°F depending on the season)
Submerge your body completely as you exhale until you are as close to possible to being out of air
Our trained technician will let you know when it's time to come back up. It takes seconds!
You will then be able to dry off and review the 4-page analysis with us

That's it!

You'll be in and out in 10 minutes.
