What InBody gives you
In under a minute you get a much clearer picture than from a regular scale or BMI. InBody shows what your body weight is made of and where it makes sense to adjust training, nutrition, or recovery.
Body composition without guesswork
You see more than total weight: skeletal muscle, body fat, total body water, and fat-free mass. That makes it much easier to tell whether you are moving in the right direction or only changing the number on the scale.
Segment-by-segment muscle and fat distribution
The report breaks down arms, legs, and trunk separately, so you can spot imbalances, weaker areas, or places where fat tends to stay. That is useful for fat loss, gaining muscle, and also for returning after a break or injury.
Data you can actually act on
The results also include practical markers such as body fat percentage, visceral fat, waist-to-hip ratio, and basal metabolic rate. These numbers make it easier to set calorie intake, training load, and next steps. Repeated measurements then show in black and white whether the plan is actually working.
Segmental analysis
Muscle and fat distribution across limbs and torso.
Risk indicators
Visceral fat, WHR index and basal metabolic rate.

Accuracy tips
- Measure every 4 to 6 weeks to track a meaningful trend.
- Come under similar conditions each time: timing, hydration and food intake.
- The cleanest comparison comes from measuring fasted.
- For the cleanest trend, measure at the same branch, on the same device, each time.
- The report is also a strong motivator because you can see real progress.
Results can vary depending on health status, hydration and other factors.
Frequently asked questions
Do I need to book in advance?
No. You can simply arrive during opening hours and arrange the measurement at reception.
Which branch can I get measured at?
At both ARENA GYM branches: Centrum (Palackého 717/11, Prague 1) on an InBody 970 and Jinonice (V zářezu 902/4, Prague 5) on an InBody 970S. Prices and terms are the same at both.
Can I use MultiSport?
Yes. With a MultiSport card you get the standard measurement free once per calendar half-year (January–June and July–December) at either branch. Just show the card at reception.
How often should I repeat the measurement?
Every 4 to 6 weeks is the recommended rhythm. That gives you a meaningful trend without too much noise.
Is it best to come fasted?
Yes. For the cleanest comparison, come fasted and under similar conditions each time.
