InBody 270S vs InBody R20
InBody 270S and InBody R20: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
InBody 270S: when to consider it
InBody270S adds whole-body phase angle to routine fat-and-muscle tracking. It is useful if you want to discuss this extra measure in a consultation. Phase angle needs context from your condition and other results, rather than serving as a stand-alone health grade.
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.
