InBody 720: when to consider it

An older detailed analyzer for following body composition and water during nutrition or sports programmes. Research mode adds regional phase angles; your report’s scope depends on the location’s settings.

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.
