Body Composition: A method of describing what the body is made of, including fat, protein, minerals and body water.


Knowing your body composition is the first step towards improving it. Having a better body composition can aid you immensely in understanding your weight, improving your overall health, and generally living a fuller, happier life. By analyzing your body composition, you can keep track of your results over time. This is an easy method for auditing your training program. If your main goal is to improve body composition, then you SHOULD start to see results that show progress towards that. Body composition testing provides measurable and repeatable data that is tracked to ensure consistency.


Fat Mass: The stuff you want to get rid of. 

Fat-Free Mass: All the mass in your body that is not attributed to fat. 

Body Water: Your body is made up of mostly water (fat, muscle, blood and other bodily fluids) Find out your hydration status and see if you are adequately hydrated.

Minerals: Primarily contained in two places (blood stream and inside bone). 

Fat: Your stored energy. 

Dry Lean Mass: Combination of the weight attributed to protein and bone mineral. 

Lean Body Mass: Combination of your Dry Lean Mass plus body water.

Bioelectric Impedance Analysis (BIA) works by sending a small electrical current into a person and measuring the opposition of that current (impedance) as it travels throughout the body’s water. Once impedance is measured, body composition is ascertained. No dunking. No pinching. No discomfort. Simply stand on the device and hold the hand electrodes to test.
