Sound familiar?
You train hard. But something is holding you back.
- Your performance has plateaued despite consistent training
- The same injury keeps setting you back
- Recovery takes longer than it should
- You take supplements without knowing what you actually need
- Fatigue and heaviness that don't match your training plan
- Your doctor only says “take a break”
Elite performance isn't about pushing harder. Biomechanics, metabolism, and the nervous system decide how your body performs, recovers, and stays healthy.
The Performance Lab.
Biomechanics
Movement analysis and functional orthopaedics: how you move, where you compensate, what slows you down.
Metabolism
Biomarker analysis and micronutrients dosed by lab values make energy, recovery, and resilience measurable.
Nervous system
HRV, sleep, and stress regulation: performance is built in recovery. We make it visible.
