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.

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.
