LQ⁵ Labs · Westlake, Austin
Know your body. Know your engine. Precise body composition, bone density, and cardiovascular fitness testing — with an expert walking you through every number.
What It Is
Together, DEXA and VO₂ max testing answer two of the most important questions about your health: what your body is made of, and how well your engine runs.
Body composition, made clear. A DEXA (dual-energy X-ray absorptiometry) scan is the gold standard for measuring bone density — and it maps your full body composition, breaking down exactly how much of you is lean mass, fat mass, and bone. Quick, painless, and precise.
Know your engine. VO₂ max measures how efficiently your body takes in, moves, and uses oxygen during exercise — the gold standard for measuring cardiovascular fitness, endurance, and metabolic efficiency.
Benefits
The data takes the guesswork out of progress.
See exactly how much muscle, fat, and bone you carry — not an estimate from a bathroom scale.
Most of us hit peak bone mass in our early 30s. DEXA shows where you stand so you can act early.
The “220 minus your age” formula can miss your true numbers by 20 beats per minute or more. A lab test measures you directly.
Low cardiorespiratory fitness is one of the strongest predictors of future health risk — and one you can train.
Easy days that are truly easy and hard days that are truly hard, so every session moves you forward.
Retest to see whether your training, nutrition, and recovery are actually working.
What to Expect
Simple prep, a straightforward test, and a clear walkthrough of your results.

Follow the simple prep guidelines below so your results are as accurate as possible.
DEXA: lie still for a quick, painless scan. VO₂ max: walk or run on a treadmill (or ride a bike) wearing a mask that measures your breathing as the effort gradually increases.
We walk you through your numbers before you leave — and what they mean for training, recovery, and longevity.

FAQ
DEXA (dual-energy X-ray absorptiometry) is the gold standard for measuring bone density. It also maps your full body composition — lean mass, fat mass, and bone — region by region.
DEXA uses a very low dose of X-ray energy — far less than a standard chest X-ray. If you are or may be pregnant, please let us know before booking.
For DEXA, wear comfortable, metal-free clothing. For VO₂ max, wear athletic clothing and avoid heavy meals and caffeine for 2 hours before your appointment.
You’ll walk or run on a treadmill (or ride a bike) wearing a mask that measures your oxygen use as you breathe. The exercise itself takes 10–15 minutes; plan for about an hour total.
Anyone who wants to train smarter, support long-term health, or stay active as they age — not just athletes.
A lot more accurate. Studies comparing smartwatch estimates to lab results found they’re off by 13–16% on average — sometimes far more. If your training decisions depend on the number, get it from a lab.
For VO₂ max, every 12 weeks if you’re following a specific training plan, or every 6–12 months for general tracking. Retesting DEXA alongside your training shows how your body composition is changing.
A DEXA scan is $50 ($40 for members) and VO₂ max testing is $99 ($79 for members). Every membership pathway includes both tests two to four times per year.
