What Does a DEXA Scan Show About Muscle, Fat, and Bone?
See what a DEXA body-composition scan measures and how DexaFit Seattle adds trained technologists, report review, visceral-fat analysis, and expanded testing options.
What Is Physical Reserve? How to Build More Capacity for Life
Physical reserve is the capacity your body has beyond what an ordinary day requires. Learn how muscle, bone, aerobic fitness, and measured energy needs can inform a focused 90-day plan.
DEXA, RMR and VO2 Max: What These Tests Tell You About Your Body
DEXA, RMR and VO2 Max measure three very different parts of your physiology: body composition, resting metabolism, and cardiovascular fitness. Learn what each test reveals, where each has blind spots, and why combining all three can lead to better training and nutrition decisions.
The Engine's Ceiling: Why VO2 Max Is the Single Best Predictor of How Long You Will Live
VO2 Max is the single strongest predictor of all-cause mortality in the clinical literature — stronger than smoking, diabetes, or coronary artery disease. Learn what it actually measures, why the "220 minus age" formula is getting your training zones wrong, and how a 12-minute clinical test reveals the cardiovascular ceiling that limits everything else.
The Armor You Cannot See: Why Bone Density Is the Most Overlooked Performance Metric
Bone mineral density governs your ability to run, lift, and absorb impact for the next three decades. Most people will never measure it until something breaks. Learn why your T-score may be the most important number you don't know — and how a DEXA scan changes the prescription.
The Idle Engine: Why You Can't Out-Train a Starved Metabolism
If you are training hard, eating less, and seeing the scale refuse to budge, you might be trying to out-train a starved metabolism. Learn why generic calorie calculators set you up for failure, and how discovering your exact 'Metabolic Floor' through clinical RMR testing is the only way to restart stalled progress.
The Muscle Tax: What the Scale Isn't Telling You About Your Weight Loss
Losing weight without measuring body composition means paying the Muscle Tax. Learn how DEXA scans and RMR testing protect lean mass during GLP-1 use and rapid weight loss to prevent metabolic rebound.
The Female Longevity Exception: Why Women Need Different Data After 40
Your body is not a bank account, and women do not age like men. Biology operates on a different hormonal timeline where menopause isn't just a transition… it’s a cliff. Stop using a male-centric longevity map and start building a blueprint based on your specific clinical data.
The Durability Decade: Why Your Movement Quality Today Dictates Your Quality of Life in 10 Years
Your body isn't a bank account. You can't just make a few deposits and expect passive interest. In biology, there is no neutral gear… you are compounding strength or decline.
Why You Crash at 2 PM: The Science of Metabolic Flexibility
Suffering from the dreaded 2 PM crash? It’s not a caffeine deficiency, it’s a fuel line problem. Discover why your metabolism is stuck in "Gas Guzzler" mode and the exact 3-step protocol to build a "Hybrid Engine" that burns fat for all-day energy.
The Most Important Vital Sign Your Doctor Isn't Checking
Is your doctor checking the #1 predictor of your lifespan? Discover why VO₂ Max is more critical than cholesterol or BMI for longevity, and how to measure your true biological age in Seattle.
Fix the Bottleneck, Not the Goal:
Most January fitness plans stall because of hidden physiological bottlenecks, not a lack of effort. Learn how to identify if your constraint is metabolic, structural, or aerobic—and how to fix it.
Why Most January Health Plans Fail by February
Motivation is high in January, but by February 15th ('Quitter's Day'), most plans fail. Discover why relying on assumptions instead of biological baselines is the trap—and how to fix it.
Stop Setting Fitness Goals. Start Building a Biological System.
You do not rise to the level of your goals; you fall to the level of your systems." Discover why traditional resolutions fail and how to install a data-driven "Biological Operating System" for 2026 using DEXA and RMR feedback loops.
The "January 1st" Trap: Why the Best Transformations Start in December
Most people treat December as a "lost" month. High performers treat it as a strategic audit. Discover the biological science of the "30-Day Lag," why waiting until January 1st puts you weeks behind, and how to use your data to engineer a strong start to 2026.
Stress, Sleep, & Strength: Engineering Holiday Resilience with Data
The holidays are a test of your nervous system, not just your willpower. Discover why chronic stress shuts down fat burning, how muscle acts as "metabolic armor," and how to use your data to engineer resilience this season.
Holiday Metabolism Myths: Why Your Body Needs a Reset, Not a Diet
The holidays don’t “break” your metabolism—stress does. Discover why "saving calories" for big meals actually backfires, how cortisol suppresses your burn rate, and how to use this winter as a strategic "foundation phase" to build muscle rather than just surviving the season.
Power Isn’t Just for Athletes — It’s the Secret to Staying Strong for Life
Most people test strength or muscle.
Almost no one tests how they work together.
That’s the missing link.
Our DEXA + Proteus Power Test shows whether your muscle is truly functional — so you can move faster, react quicker, and stay powerful for life.
👉 Book your test and find out which Power Profile you’re in.
Is Your VO₂ Max Lying to You?
Most people look at VO₂ Max as the gold standard of fitness—but without factoring in lean mass, it can be misleading. Discover how DexaFit’s VO₂ + DEXA combo reveals your true aerobic efficiency and longevity potential.
The Truth About RMR and What It Really Tells You
Your metabolism isn’t just a number — it’s the engine driving your energy, weight, and performance. Learn what your Resting Metabolic Rate (RMR) really reveals about your health, why generic calculators get it wrong, and how DexaFit Seattle uses clinical testing to design precise nutrition plans that work.
