Hydrostatic body fat testing

Why Hydrostatic Testing?

As body fat testing, rather than simple scale weight, has become "the standard" in this new millennium, Hydrostatic Testing (Underwater Weighing) has become universally regarded by industry experts as the "Gold Standard" in body fat testing.

The hydrostatic testing method has been around for over 50 years and is based on Archimedes principle which states "that when a body is submerged in water, there is a buoyant counter force equal to the weight of the water which is displaced". Since bone and muscle are denser than water, a person with a larger percentage of lean body mass will weigh more in the water and ultimately have a lower body fat percentage versus someone with less lean muscle mass. By obtaining your land weight and water weight (based on buoyancy), our specialized program can calculate your body fat as a percentage of your total weight.

FitnessWave has been the pioneer in hydrostatic testing for over a decade. We strive to provide accurate and affordable hydrostatic testing to our clients with a professional touch. Check out a sample hydrostatic report or jump over to the calendar to schedule an appointment.


the hydrostatic testing process:

  1. your test will occur in our mobile unit
  2. your reserved testing time is 15 minutes
  3. we have private areas on the mobile unit for you to change your clothes
  4. you will need your bathing suit and towel
  5. you will receive a summary of your results immediately and a full report the next day in your email

PLEASE NOTE: this testing requires you to be fully underwater for a few seconds. Your hair will get wet! This occurs in a hot tub with water that is as warm as a bath (approximately 92 degrees - 100 degrees). The water is chlorinated or brominated to kill bacteria and is changed frequently!
