Why personal training alone often falls short.
A trainer can manage your workouts. But they never understand the underlying physiology driving your results—they don't have a clear picture of your hormone profile, nutrient deficiencies, body composition, metabolic or cardiovascular health.
They count your reps for an hour in the gym while the rest goes unmanaged.
Valence Health solves that. Your Performance Physical establishes the baseline. Our team reviews your data and develops a coordinated training, nutrition, supplementation, and recovery plan.
We test, look at your results, implement, then re-test again—so progress is measured, not assumed.
This isn’t personal training. It’s a protocol built around your unique physiology.
The Performance Physical.
Every well-executed plan starts with data:
Advanced blood panel — Comprehensive biomarkers to assess your hormonal, metabolic, cardiovascular, and general health — measured against optimal, not “sick-population average” ranges.
DEXA scan — DEXA provides the most accurate assessment of your body composition available: lean mass, body fat, visceral fat, and bone density.
VO₂ max — The gold-standard objective measure of cardiorespiratory fitness and aerobic capacity, establishing a measurable baseline for endurance, energy, recovery, and long-term physical capacity.
Resting metabolic rate — A direct measurement of how much energy your body uses at rest, grounding your nutrition recommendations in your actual physiology instead of generalized calorie targets.
Then we synthesize your testing into a Clinical Review & Personalized Plan — identifying your baseline, highest-leverage opportunities, and a practical roadmap for training, nutrition, and recovery prioritized over the next 90 days.

Health data is only useful when it changes what you do.
Most men already have pieces of the picture.
Annual bloodwork. A fitness tracker. A training program. Perhaps a body-composition scan or nutrition plan.
The problem is rarely a complete absence of information. It is that the information sits in separate places, was gathered at different times, and has never been translated into one coherent course of action.
The Valence Performance Physical brings the most relevant measures of health and physical performance together in a single assessment.
Your results are reviewed as a whole, then translated into a personalized plan for training, nutrition, recovery, and the priorities that deserve your attention first.
No collection of disconnected reports. No generic list of recommendations.
A measured baseline—and a clear plan built from it.
Everything you need to know before applying.
