InBody 120: when to consider it

InBody120 is useful for following fat and muscle while changing your diet or activity. A meaningful consultation benefits from the full computer-generated report; the small display shows only part of the results.

InBody R20: when to consider it

R20 was developed for home body-composition monitoring and also appears in some fitness services. It gives a basic muscle-and-fat overview. For a more detailed consultation, it matters whether the provider also uses the computer report.

Fat-free mass is not pure muscle mass. A single result is not a diagnosis. Different devices and similarly named metrics may use definitions that are not interchangeable.
