InBody 770S: when to consider it

A newer generation for nutrition and clinical follow-up with a detailed water report. Useful for discussing fat and muscle changes in the context of water distribution and phase angle, including individual body regions.

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.
