InBody 370

When this test is useful

Use the full model name when identifying InBody 370. The S denotes a different model: you cannot automatically add 370S specifications or outputs to an older 370 report. The original 370 also appears in Czech services with consultation, including the University of West Bohemia’s Faculty of Health Care Studies. Its report offers a starting point for three questions: how much weight is fat, what is happening to skeletal muscle, and how is lean mass distributed? Bring your old sheet to a follow-up appointment. Reviewing several visits together is often more useful than judging one number.

What the results tell you

Skeletal muscle mass, fat mass and percent body fat give weight more context. If weight stays similar while fat falls across several visits and the muscle estimate is maintained, you may see progress that a bathroom scale misses. A single test does not establish that trend.

Separate arms, legs and trunk help reveal differences between sides. The result estimates lean mass rather than isolated muscle volume or strength. For a return after injury, combine these values with a movement assessment; the table alone does not show how you use the limb.

TBW complements the fat-free mass estimate. Protein and mineral values come from the body composition model: they are not blood tests or bone density measurements. For swelling or bone health concerns, choose further assessments with a health professional.

BMI uses height and weight; percent body fat adds an estimate of composition. WHR is an estimated waist-to-hip ratio. These measures have different meanings and need not change together. The original 370 standard brochure does not list visceral area or level.

BMR is a calculated estimate of resting energy. The summary score and automatic fat or muscle adjustment suggestions can start a conversation, but are not mandatory targets. A realistic plan needs to fit your activity, health and what you can maintain over time.

How the device measures

370 uses segmental bioimpedance. A weak electrical signal passes between hand and foot electrodes; measured impedance is used to estimate body water and other components. Multiple frequencies do not mean that every reported value was measured independently. Interpretation also needs the circumstances of the visit.

Test procedure and preparation

Agree on preparation beforehand and keep it similar on repeat visits. Avoid testing immediately after intense exercise or a sauna. Remove shoes, socks and heavy accessories, then stand quietly for a while. Hold your arms away from the body as instructed. Declare a pacemaker or another electronic medical device beforehand; the manufacturer prohibits use in that situation.

Limitations and influences

The standard brochure report does not list ECW/TBW or whole-body or segmental phase angle. Frequency count alone does not establish their availability. 370 requires stable standing with hand electrodes. Someone unable to maintain that position safely needs another approach. Legacy exports and a provider’s extended software may use different reports. Check labels and units before comparing two values.

Choosing a device and service

370S retains basic segmental analysis, with a faster test, different design and visceral fat level in its standard manual. For fluid ratios or phase angle, also compare 770, 770S and 970S. A higher model number alone does not guarantee a better choice; the information you actually need matters.
