BOD POD® Body Composition Testing

What is a BOD POD®

The BOD POD® is an air displacement plethysmograph which uses whole-body densitometry to determine body composition (fat and fat-free mass) in adults and children, and can accommodate a wide range of populations. A full test requires only about 5 minutes, and provides highly accurate, safe, comfortable, and fast test results.

Why get tested?

Anyone who's serious about making progress towards their fitness goals needs accurate information. For example, if you've lost 5 lbs, you may think that's great, but how much of that was fat, and how much was muscle? You can't rely on scale-weight only to know if you're making the progress you aim to achieve.

Getting a Bod Pod body fat test can answer this question. If you're trying to lose body fat but maintain (or increase) muscle mass, you'll need a detailed analysis of your body composition changes. 


The better information you have the better decisions you can make in achieving your goals.

Is it accurate?

The BOD POD® which uses air displacement technology is considered the Gold Standard in body composition measurement.  It is as accurate as hydrostatic (underwater) weighing, but much quicker and easier to perform.  The range of error for this test is +/- 1 to 2.7%.  

What is the difference between weight loss and fat loss and why should I care?

Overall weight lose is a good thing if you are looking to lighten the load on your joints but losing muscle mass is never desirable.  Sometimes when you’re working hard and eating right the scale won’t move and that can be frustrating but you are probably losing fat and gaining muscle at the same time. This is a good thing and why you need to be retested to make sure that is the case.  Fat takes up a lot more room than muscle so you should feel your clothes fit better and your ‘mirror test’ improve.

What is the BOD POD® test like?

The BOD POD® test is a very simple (but highly accurate test)  

  • You will dress in a form fitting swimsuit or compression shorts and sport bra (without padding) for women.   
  • You will be asked a few questions to calibrate the machine for your custom measurement. 
  • You will be provided a silicone swim cap that must be worn during the test.
  • Then the technician will have you step on a scale so the machine can capture your body weight.
  • You will then be asked to sit comfortably in the BOD POD chamber.
  • The technician will run 3 tests that will each last about 40 seconds.  Between each test the door will be opened.
  • At any time you may cancel the test by pressing the cancel button located inside the BOD POD chamber.
  • After the third test is complete you will step out of the chamber and the technician will review the results of your test with you.
  • You will be provided a custom test printout that will give you the results of your BOD POD test and other important data.

How often should I be tested?

Knowledge is power and the the more frequently you test the more information you will have to track the effectiveness of your nutrition and training.  We recommend at least quarterly tests to effectively make decisions to achieve your goals.
