Stop estimating your body.Measure it in the South Bay.
Clinical-grade DEXA body composition, VO₂ Max, and RMR testing is coming to Artesia Blvd in Redondo Beach, running on the same equipment class that research labs and medical practices rely on.
The measured truth beneath every plan you have ever tried.
A scale reports one number. A watch closes a ring. A blood panel flags one marker. Not one of them tells you what your body is built from, what it can do under load, or how much fuel it burns to stay running.
DexaFit started in Chicago in 2011 on a single principle: measure the body directly rather than infer it from the outside. That work has since grown into a network across four continents, grounded in over a decade of real-world data. That standard is now setting up in the South Bay, a short drive from the beach cities of Redondo, Manhattan, and Hermosa, and open to the whole of Los Angeles County.
You will not walk out with a diet, a supplement, or a training split. You will walk out with the numbers that show whether the routine you already keep is doing what you think it is. Measure first. Decide after.
Three tests that trade guesswork for a clear read on your body.
Each one covers a blind spot your scale, your mirror, and your wearable leave wide open.
DEXA Scan
Fat, muscle, and bone, mapped region by region.
An open-air scan sweeps you from head to toe and separates fat, lean muscle, and bone density, down to the visceral fat wrapped around your organs. It reads body fat to within roughly ±2%, while a smart scale can drift 8 to 15% off.
VO₂ Max Test
The real ceiling of your cardio engine.
A guided effort test measures how well your body takes in and uses oxygen, whether you run The Strand at sunrise or train for the LA Marathon. Across 122,007 people, this marker tracked all-cause mortality more closely than smoking, blood pressure, or cholesterol. Your watch guesses at it. We measure it.Mandsager et al., JAMA 2018; N = 122,007.
RMR Metabolism Test
The calories your body burns at rest.
A few calm minutes of easy breathing read your resting metabolism straight from your breath, instead of dropping you into a generic formula. App and calculator estimates can be off by 20 to 30%. Your nutrition should be built on your real number.
Clinical-grade results, read against the benchmark that fits you.
A raw number tells you close to nothing on its own. Every result here is measured against age and sex matched reference ranges, then put into plain language you can use. You leave knowing where you stand and what to do next.
DexaFit works alongside your physician, your coach, and your wearables, never in place of them. We are the baseline everything else in your plan gets checked against.
Return a few months on and the numbers report back without spin: what improved, what held, and whether the work you put in actually paid off.
