The Science Behind Custom Fit SF’s Longevity Blueprint
The conversation around wellness is evolving. It's no longer just about extending your lifespan, but about enhancing your healthspan—the years you spend feeling healthy, strong, and capable. Modern science allows us to be proactive about aging rather than simply reacting to health issues as they appear [1]. The Custom Fit SF Longevity Blueprint is a tool for this data-driven approach to long-term health. It replaces guesswork with science to create a personalized plan just for you.
What is the Custom Fit SF Longevity Blueprint?
The Longevity Blueprint is our most comprehensive health and performance assessment at Custom Fit. Its purpose is to provide a complete, data-driven understanding of your body, along with a clear, actionable plan to improve your health. It moves beyond generic advice by using gold-standard testing methods trusted by scientists and medical professionals.
The Blueprint is built on four key pillars:
- DEXA Scan
- VO₂ Max & RMR Testing
- Advanced Bloodwork
- Genetic Testing
The Four Scientific Pillars of Your Personal Blueprint
Each test offers a unique and critical piece of the puzzle to understanding your overall health and longevity potential. Together, they create a detailed picture of your body's specific needs.
Pillar 1: DEXA Scan for Body Composition & Bone Health
A DEXA scan is the gold standard for measuring body composition, offering precise insights that go far beyond weight or BMI. It measures:
- True body fat percentage: The actual amount of fat tissue versus lean tissue.
- Lean muscle mass: Identifies how much muscle you have in each limb, helping to spot imbalances.
- Visceral fat: The hidden fat around your organs, a key indicator of metabolic health risk.
- Bone density: A crucial metric for long-term skeletal health and preventing fractures.
Understanding these metrics is powerful. For example, high visceral fat is linked to chronic disease, and strong bone density is vital for maintaining mobility. This data is a cornerstone of effective personal training and nutrition coaching [1].
Pillar 2: VO₂ Max & RMR Testing for Cardiovascular Fitness & Metabolism
VO₂ max is the most accurate measure of cardiovascular fitness and a strong predictor of longevity. This test reveals:
- Your VO₂ max score and how your fitness compares to your peers.
- Personalized heart rate training zones for more effective workouts.
- How your body uses fat versus carbohydrates for fuel.
This pillar also includes a Resting Metabolic Rate (RMR) test, which measures your unique metabolism—the calories you burn at rest. This data is essential for creating an accurate nutrition plan for any weight or performance goal.
Pillar 3: Advanced Bloodwork for Internal Health Signals
This test is like a look "under the hood" at your metabolic health. By analyzing over 50 markers, it provides key insights into:
- Blood sugar control and insulin sensitivity.
- Cardiovascular risk markers like cholesterol levels.
- Inflammation and recovery capacity.
- Thyroid and hormone health.
- Key nutrient deficiencies, such as Vitamin D or B12.
This allows for the early detection of potential issues, empowering you to make targeted changes before they become major problems.
Pillar 4: Genetic Testing for Personalized Insights
Genetic testing reveals your predispositions, not your destiny. This test provides personalized insights to help fine-tune your lifestyle based on your unique DNA, including:
- How your body may respond to macronutrients (fats, carbs, proteins).
- Your sensitivity to caffeine, alcohol, and sodium.
- Predispositions for inflammation and recovery needs.
- Your natural exercise response patterns.
This information helps you work with your body's unique makeup to optimize your nutrition and fitness.

A Proactive Approach to Your Healthspan
The science of aging is clear: our lifestyle choices have a huge impact on how well we age [3]. With studies showing that the average person spends nearly a decade of their life dealing with disease, it’s crucial to shift from a reactive model to proactive, personalized healthcare [2]. By understanding your body's unique data, you take a scientifically-backed step toward improving your healthspan. This proactive philosophy is central to all our custom wellness programs, which integrate training, nutrition, and recovery.
