InBody 370S vs InBody R20
InBody 370S 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 370S: when to consider it
InBody370S provides a detailed muscle-and-fat overview for training or nutrition consultations. Alongside whole-body values, it shows regional distribution and visceral fat level. It suits repeat monitoring when you will make use of those measures.
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.
