Whether in gyms or at home, we will be conducted to measure body metrics on the family scale or body composition analyzer as the way to indicate how healthy we are. Normally we said about body composition mainly means body weight, one of the main consist of body compositions.


In physical fitness, body composition is used to describe the percentages of fat, bone, water and muscle in human bodies. Because muscular tissue takes up less space in the body than fat tissue, body composition, as well as weight, determines leanness. Two people of the same gender and body weight may look completely different because they have different body compositions.


By knowing the body compositions, you could get a clearer picture of your health, being a clear indicator of whether your body fat percentage is in a healthy range—10-20 percent for men and 18-28 percent for women. This knowledge is important to determine how to reduce or prevent the risk of developing these diseases, and know body strengths and weakness, so that it helps you determine the right approach to exercise.

When you are losing weight to lose fat not lean body mass, the weight scale will not track the change, you need the professional body composition analyzer instead, to monitor every percentage of body compositions, including weight, lean body mass to know what the body is changing.

How to measure your body composition?

Skinfold Thickness (Calipers)

The most commonly used method measures subcutaneous fat by pinching the skin and using a caliper device to measure the thickness of the skin fold in several sites on the body. The chest, arms, abdominals, and thighs are usually measured, although some protocols may include as many as seven different parts of the body


Inexpensive, non-invasive. Reliable and useful for measuring body fats in specific regions of the body.


Use is limited to moderately overweight and thin subjects.

Accuracy and reliability can vary, depending on the skill of the technician and the brand of caliper.

Estimate regional fatness, but doesn’t give an accurate representation of body composition.

Hydrostatic Weighing

Underwater weighing calculates the total body fat by the density of the body. It is based on Archimedes’ principle: when an object is submerged in water, the difference between the mass of the object in the air and its mass in water is the object’s volume.

Body density =  Mass of air /(Mass of air – Mass of water )


Reliable and consistent in determining body density with long history of use in clinical settings and sports.


Not easily accessible. Residual lung volume can influence its accuracy. The density of lean mass is an assumed constant, but varies with age, sex, and fitness level.

Dual Energy X-Ray Absorptiometry (DEXA)

DEXA is an imaging method that measures the body weight in terms of BMC, lean, and fat based on the decrement of X-ray on the images obtained by exposing to two different X-rays.


Highly accurate and reproducible. Can determine body composition in specific body regions. Gold standard for analyzing bone density.


Expensive equipment required. Small amount of radiation exposure.

Bioelectric Impedance Analysis (BIA)

Bioelectrical Impedance Analysis (BIA) is a method of measuring impedance by applying alternating electrical currents to a user to measuring their volume of water through impedance values.

This non-invasive method involves the placement of electrodes on a person’s feet, hands, or both. A low-level electrical current is sent through the body, and the flow of the current is affected by the amount of water in the body. BIA devices measure how this signal is impeded through different types of tissue (muscle has high conductivity but fat slow the signal down).


Inexpensive, safe, quick, and require little-to-no technical expertise.

Good for monitoring changes within individuals over time.


Because it assumes a typical body water content, validity is best in young, healthy, and normally hydrated adults.

Accuracy can be influence by disease states and tends to overestimate lean mass in obese individuals.

How Visbody measures the body composition

For conducting the accurate body compositions, Visbody embedded with the 8-electrode multi-frequency BIA and infrared scan(no harm to human body) tech, to measure 15 key measurements of body compositions to get accurate and trustworthy data and know every details of body components.

With infrared scan tech, Visbody body scanner is the world 1st body analyzer that used in every gyms to measure body composition even with your clothes on, which makes the Visbody the first option for gym and fitness center to provide custom service for memberships.

There are multi-frequency BIA pads on the foot and handle. While you are testing, place hands and foots on the right areas to conduct test. The most advantage of Visbody is its accurate report, which to be 0.98 to DEXA scan or the ‘Golden Standard’, it is far more accurate than regular scales and other conventional 3D body analyzers.
