Hume Pod vs. DEXA vs. InBody: Which Body Composition Tracker Is Right for You?

I’ve spent more than 15 years helping people improve their fitness as a Master Fitness Trainer, and one thing I’ve learned is that the scale rarely tells the whole story. Whether I’m training clients, coaching athletes, or tracking my own progress, body composition data matters.

I’ve personally tested the following three: DEXA scans, InBody scans, and the Hume Pod. Each takes a different approach to measuring body composition, and each comes with its own advantages and trade-offs.

If you're trying to decide which option makes the most sense for your goals, budget, and lifestyle, it’s worth taking a closer look at how they compare when it comes to accuracy, convenience, cost, and long-term tracking. Here are my honest thoughts after trying all three.

If You’re Looking at Cost Per Scan... Hume Pod

DEXA scans provide detailed body composition data, but they typically cost $50-$200+ per session depending on the facility and region, which gets expensive quickly. They’re also not usually covered by standard insurance for body composition purposes. I had to drive over 2 hours to get a DEXA scan, so if you factor in gas prices, this was a really expensive option.

InBody scans are more affordable at around $10-$50 at most gyms and wellness facilities, but you’re still paying per scan and are limited by where the machines are available. Luckily I do have access to one through my gym, but that may not be the case for everyone.

The Hume Pod is a one-time purchase. Once it’s in your home, you can scan as often as daily with no per-session cost. It’s also HSA/FSA eligible, which makes clinical-grade data even more practical long term. I personally like to scan myself every morning, so this has been a gamechanger for me.

Winner: Hume Pod

If You Want The Most Accurate Results...DEXA

DEXA deserves respect. It’s the clinical gold standard, using X-ray based, direct tissue measurement, with a ±1-2% margin of error. It’s also not sensitive to hydration or meal timing.

InBody is BIA-based, which means hydration can throw off results. A single glass of water can shift fat readings by 2-5 percentage points, so accuracy under real-world conditions can be significantly lower.

The Hume Pod delivers 98% DEXA-level accuracy from home, which is more than enough for my day to day tracking. While DEXA may win for gold-standard accuracy, Hume Pod wins in my eyes for consistent, trackable, everyday use.

Winner: DEXA

If Convenience and Access Matter... Hume Pod

DEXA requires booking an appointment, traveling to a specialized facility, fasting for 4-6 hours, and wearing specific clothing. Most people can realistically do it every 3-6 months.

InBody is faster, more accessible, and available at many gyms, but you still need to leave home and match testing conditions each visit.

The Hume Pod gives me a 30-second scan at home, any time, with bare feet. No appointments, no facilities, and no fasting requirements required.

Winner: Hume Pod

If You Want Depth in Metrics... Hume Pod

DEXA tracks bone density, fat mass, lean mass, visceral fat, and regional breakdowns. It’s strongest for bone density data specifically.

InBody tracks muscle mass, body fat percentage, hydration, and segmental analysis, but it does not measure bone density.

The Hume Pod tracks 45+ body composition metrics, including fat mass, muscle mass, visceral fat, bone density, hydration, and metabolic age. That’s far beyond what a standard scale offers. All results are synced up to the Hume app which is organized into trend charts, progress tracking, and seamless integration with Apple Health, Google Fit, and Fitbit.

Winner: Hume Pod

If You Want More Useful Data Over Time... Hume Pod

DEXA and InBody are both designed for periodic check-ins, usually every 1-6 months. That can make meaningful change hard to detect at that sort of frequency.

The Hume Pod is designed for consistent, daily use, so I can see how my body responds to training blocks, nutrition shifts, and recovery in real time. That week-over-week feedback is the kind of data I can actually use.

Winner: Hume Pod

The Ultimate Winner... Hume Pod

DEXA is still the clinical benchmark, and InBody can be useful when it’s available. But for regular, actionable body composition tracking, I’d choose the Hume Pod.

It gives me 98% DEXA-level accuracy in a 30-second scan, 45+ body composition metrics, daily tracking built in, seamless app integration, and HSA/FSA eligibility.For me, the best body composition tracker is the one I can use consistently. That’s why the Hume Pod comes out on top.
