Key Takeaways

InBody analysis measures lean muscle mass, body fat percentage, visceral fat, segmental muscle distribution, and total body water — giving you a precise picture of what your body is actually made of
The scale only shows one number; InBody shows you whether that number is fat, muscle, or water — which completely changes how your program is built
Research shows bioelectrical impedance analysis (the technology behind InBody) correlates 95%+ with DEXA scan results, the clinical gold standard for body composition
Every new PEAKFIT client receives a complimentary InBody scan as part of their free consultation
Retesting every 6-8 weeks gives you objective data on whether your program is working — and what to adjust if it’s not

When most people start a fitness program, they step on the scale. When they want to check progress, they step on the scale again. The problem is that the scale has no idea what’s changed. It can’t tell you if you lost fat, lost muscle, or just lost water. It can’t show you whether the strength training is working or whether your nutrition is actually fueling muscle growth.

InBody can tell you all of that — and at PEAKFIT Studio in Arden, NC, it’s the starting point for every client’s program.

What InBody Measures

InBody devices use bioelectrical impedance analysis (BIA) technology. A small, imperceptible electrical current passes through the body; different tissues (muscle, fat, bone, water) resist this current at different rates, allowing the device to calculate composition with high accuracy.

A standard InBody scan at PEAKFIT takes 15-20 minutes and produces a detailed results sheet covering:

Total body water — intracellular and extracellular fluid balance
Lean body mass — total muscle tissue across the body
Body fat mass — total fat weight
Body fat percentage — the ratio of fat to total body weight
Segmental lean analysis — muscle mass broken down by right arm, left arm, trunk, right leg, left leg
Visceral fat level — fat stored around internal organs (linked to metabolic health risk)
Basal Metabolic Rate (BMR) estimate — calories burned at rest based on lean mass
InBody Score — an overall body composition health score

That segmental breakdown is particularly useful. It reveals imbalances between left and right sides, between upper and lower body, and between arms and legs — information that directly shapes how your personal training program is designed.

Why InBody Is More Useful Than the Scale

The scale number tells you about gravity. InBody tells you about composition.

Consider two clients, both 165 pounds. Client A has 38% body fat and low lean mass. Client B has 22% body fat and strong segmental lean mass across all limbs. They weigh the same. Their health, performance, metabolism, and ideal training approach are completely different.

Now consider a single client over 12 weeks of consistent training. The scale hasn’t moved. Are they failing? Not necessarily — they may have lost 6 pounds of fat and gained 6 pounds of muscle simultaneously. That’s a meaningful body composition change that the scale completely misses. InBody would show both.

This matters because training programs built on scale data alone often miss the mark. A client losing muscle along with fat needs a completely different nutrition adjustment than a client gaining muscle while maintaining fat percentage. Your coach at PEAKFIT can only see those differences with InBody data.

The Accuracy Question

Skeptics of bioelectrical impedance technology often point out that early BIA devices were notoriously inaccurate. InBody’s more recent multi-frequency, multi-segmental technology is in a different category.

A 2016 study in Clinical Nutrition compared InBody 770 results against DEXA (Dual-Energy X-ray Absorptiometry) scan results — widely considered the gold standard for body composition measurement — in 80 healthy adults. The correlation between InBody and DEXA for fat-free mass was r=0.97, and for body fat percentage was r=0.95, demonstrating clinical-grade accuracy for body composition assessment (Clinical Nutrition, 2016).

A separate 2020 review in Clinical Physiology and Functional Imaging evaluated InBody across multiple populations and consistently found correlation coefficients above 0.90 with reference methods, supporting its use in research and clinical settings (CPFI, 2020).

For practical purposes in a fitness setting, InBody is accurate enough to detect meaningful changes in body composition between scans and to guide evidence-based adjustments to training and nutrition.

How PEAKFIT Uses InBody Data

At PEAKFIT, InBody isn’t just a cool piece of equipment — it’s the measurement backbone of the entire program.

At the start: Your initial InBody scan establishes your baseline. Before any workouts are designed, before any nutrition advice is given, your trainer and nutrition coach know your actual lean mass, fat mass, visceral fat level, and segmental muscle distribution. This tells them immediately what the priority is — whether that’s building lean mass, reducing body fat, or addressing left-right imbalances that could lead to injury.

During the program: A retesting schedule of every 6-8 weeks lets the team see what’s actually changing. If lean mass is going up and fat mass is going down — the program is working, and you can stay the course. If lean mass is dropping alongside fat mass — nutrition needs adjustment, likely more protein or total calories. If a muscle imbalance is persisting — the training program gets modified to address it.

Connecting to nutrition: InBody data feeds directly into personalized nutrition plans at PEAKFIT. Your BMR estimate from the scan helps determine appropriate caloric targets. Your lean mass drives protein recommendations. Your body fat percentage helps set realistic, staged goals. This connection between measurement and nutrition is part of what makes the PEAKFIT 360 approach different from programs that guess at nutrition rather than calculating it.

What Affects InBody Accuracy

To get the most accurate results from your InBody scan, timing and hydration matter.

The scan is most accurate when:

You have not eaten or drunk anything (other than water) for 2-3 hours before the scan
You have not exercised in the 12 hours prior
You are well hydrated — not immediately post-exercise when you may be dehydrated

Large meals, intense exercise, and dehydration all temporarily affect body water balance, which shifts the bioelectrical readings. Retesting at roughly the same time of day and under the same conditions produces the most meaningful comparison data between scans.

Your PEAKFIT team will walk you through the preparation guidelines before your first scan.

Pricing

InBody body composition analysis at PEAKFIT Studio is priced at:

$25 for a standalone scan
$45 for a scan with a brief results consultation
$100 for five sessions (ideal for tracking progress over a 6-month program)

All new clients receive a complimentary InBody scan as part of the free consultation. This gives the PEAKFIT team real data to build your program around from day one — and gives you a clear, measurable starting point.

Frequently Asked Questions

Is InBody analysis safe?

Yes. The bioelectrical current used in InBody devices is extremely low — far below the threshold of sensation or physiological effect for most people. It’s not recommended for individuals with implanted electronic devices (pacemakers, etc.) or for use during pregnancy.

How long does a scan take?

The physical measurement takes about 15-20 seconds. Reviewing and explaining your results typically takes an additional 10-20 minutes depending on how many questions you have.

Can InBody detect visceral fat?

Yes. Visceral fat — fat stored around the organs in the abdominal cavity — is strongly linked to metabolic disease risk, including type 2 diabetes and cardiovascular disease. InBody quantifies visceral fat level on a scale that helps your trainer and nutrition coach assess and track this health marker over time.

How is InBody different from a body fat scale at home?

Home body fat scales use single-frequency BIA at only two points (your feet). InBody uses multi-frequency BIA across eight electrodes on your hands and feet, measuring multiple body segments separately. The home scale gives you one unreliable number; InBody gives you a clinically accurate breakdown of your composition.

What if my numbers don’t look good?

That’s exactly the point of the scan — to see where things actually stand so the team can build a program around your real numbers. Your starting point is just data, not a judgment. The PEAKFIT team has seen every body type and fitness history; the results guide the program, they don’t define you. See what real clients say about their experience getting started at PEAKFIT.
