Why I made this guide
Many of my patients report feeling stuck in their work outs, but understanding if they are making true functional progress.
That’s because conventional fitness metrics—like scale weight or hours logged at the gym—don’t tell the full story:
- Strength, mobility, and endurance decline long before injury or dysfunction shows up
- “Normal” fitness does not equate to optimized, longevity-focused function
- You can’t fix what you don’t measure
With this guide, you’ll uncover what you should be tracking—and how to make it actionable.
What’s Inside the Guide
What You’ll Learn:
- Targeted assessments: strength (muscle resilience), mobility (range-of-motion, balance), and cardio (heart/pulmonary efficiency)
- Optimal—not just “acceptable”—benchmarks that align with long-term joint health, metabolic efficiency, and functional independence
- How to interpret raw numbers into real decisions: not just data, but insights for progress
- Practical tools for self-assessment, including suggested routines, performance tests, and wearable/enhanced monitoring recommendations
- A foundational resilience checklist: early-warning signs for injury, decline, or metabolic disruption
Includes breakdowns for:
- Muscle strength (e.g., grip, push/pull ratios)
- Postural and balance screening
- Cardiovascular endurance (e.g., sub-max testing, recovery rates)
- Functional flexibility and movement patterns
Why It Matters
Fitness is about being adaptive and durable for decades to come.
By measuring key performance indicators now, you can:
- Mitigate injury, maintain joint function, and preserve quality of life
- Support metabolic and vascular health through muscular efficiency
- Extend your healthspan—not just your lifespan—by future-proofing your physical capacity
- Take ownership of your performance data instead of relying on arbitrary standards
