InBody 770 vs InBody BWA 2.0S
InBody 770 and InBody BWA 2.0S: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
InBody 770: when to consider it
For detailed nutrition or clinical consultations and training follow-up. Alongside fat and muscle, it provides a dedicated water report, water distribution and phase angles. Testing takes place standing up.
InBody BWA 2.0S: when to consider it
The newer BWA 2.0S combines detailed water results with composition and offers a shorter test than the original BWA. Testing can also take place while lying or seated. It is mainly intended for care where a professional follows water distribution and muscle quantity over time.
