WHAT IT IS
The work, in plain terms.
Lean mass sinks. Fat floats. That is the Archimedes principle behind hydrostatic weighing: your body density is measured underwater, and body fat is calculated from it. It is the most precise body-fat measurement available, and it is the reason this studio can talk about your body in real numbers instead of guesses.
The result is reviewed with your coach, so the number becomes a plan: what to protect, what to change, and what to re-test later. If you are starting a rebuild, this is the cleanest baseline you can give yourself.
WHO IT IS FOR
- You want a real body-fat number, not an estimate from a bathroom scale.
- You are starting a rebuild and want a baseline before anything changes.
- You want to compare progress using the same method each time.
WHAT TO EXPECT
Three steps, no mystery.
- 01
Call to book
Tell us you want a hydrostatic test. We will explain how to prepare and what to bring.
- 02
The test
You are weighed in and out of the water, and the test is run at the studio.
- 03
The readout
Your result is reviewed with your coach, alongside what it means for your training and food.

Estimates only — ask a coach before planning a cut. Hydrostatic testing measures the real number this planner is approximating.
QUESTIONS
The useful answers.
What should I wear or bring?
Wear a swimsuit. Call before your appointment and we will tell you exactly what to bring and how to prepare.
Is hydrostatic testing safe?
It is a measurement, not a medical treatment. If you are pregnant or have a medical condition, speak with your doctor first, then call us with any questions.
How is this different from my smart scale?
A smart scale estimates body fat from an electrical current and an equation. Hydrostatic weighing measures your body density directly. Our guide, The scale is not a body-fat test, walks through the difference.
