InBody 120 vs InBody 370S
InBody 120 and InBody 370S: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
InBody 120: when to consider it
InBody120 is useful for following fat and muscle while changing your diet or activity. A meaningful consultation benefits from the full computer-generated report; the small display shows only part of the results.
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.
