Fit3D vs Home Smart Scales: Is It Worth Coming In for a Body Fat Test?

You’ve Got a Scale That Tracks Body Fat — So Why Bother With Fit3D?

Home smart scales are everywhere. They’re cheap, easy to use, and claim to measure body fat, muscle mass, and more. So the question comes up:

“If I have a smart scale at home, do I really need to do a Fit3D scan?”

At Excel Health & Fitness in Manteca, we get it, convenience matters. But when you look deeper at what you’re really getting from each, the difference becomes clear.

Let’s break it down.

How Smart Scales Work

Most home smart scales use BIA — bioelectrical impedance analysis. They send a small electrical current through your body (you don’t feel it) and estimate fat and lean mass based on resistance.

Pros:

  • Convenient

  • Affordable ($25–$150)

  • Syncs to your phone or app

Cons:

  • Easily thrown off by hydration, time of day, food, alcohol, and even your foot placement

  • Doesn’t track shape, posture, or visible change

  • Not reliable for small body changes or short-term tracking

How Fit3D Scans Work

Fit3D uses infrared cameras to scan your body from head to toe. You get a 3D model, body fat estimate, and precise measurements from over 400 data points — including posture and balance.

Pros:

  • Extremely consistent and visual

  • Shows you how your body is changing, not just your weight

  • No contact, no current, no weird readings

  • Gives more than just numbers, it gives context

Cons:

  • You need to come into the gym

  • Not something you do every day (and you shouldn’t)

Fit3D vs Smart Scale: Key Differences

Accuracy

  • Smart Scale: Often inconsistent, especially day-to-day

  • Fit3D: Designed for consistency and repeatable comparisons

What You Can Track

  • Smart Scale: Body fat %, weight, maybe hydration

  • Fit3D: Full-body shape, symmetry, body fat %, posture, measurements, progress visuals

Frequency

  • Smart Scale: Daily (but can be misleading)

  • Fit3D: Monthly or every 6 weeks — when real change happens

Motivation

  • Smart Scale: Often frustrating

  • Fit3D: Encouraging, detailed, and easy to understand

When to Use Each

If you just want a quick check-in and don’t care about precision, your smart scale is fine.

But if you:

  • Are serious about tracking fat loss or muscle gain

  • Need motivation from something more than the number on the scale

  • Want to compare real changes in your shape and size over time

Then Fit3D is absolutely worth it.

Why Our Members Do Both

A lot of our members still use smart scales — and that’s okay. But they come in every 4 to 6 weeks for a Fit3D scan to get the full picture. That way, they aren’t guessing. They know exactly how their body is changing.
