InBody 520: when to consider it

An older model for following fat, muscle and water during nutrition or exercise changes, and for understanding past results. Includes ECW/TBW and lean-mass distribution across the arms, legs and trunk.

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.
