Data-Driven Testing for Longevity and High Performance
You’re Doing the Work. You Just Want to Know It’s the Right Work.
Most people guess their way through training and “healthy living.” One coach talks intervals, another talks mobility, your doctor talks blood work and none of it connects.
We built Nxxt Labs to fix that.
We measure three pillars that drive performance and long-term health:
- Heart & Metabolism: VO2 Max, thresholds, and resting metabolic rate
- Movement & Joints: AI-based 3D movement analysis, range of motion, asymmetries
- Neuromuscular Control: Force plate testing for power, stability, and force absorption
Start With the Outcome You Care About Most
Different goals, same philosophy: objective data, explained in plain language, and immediately actionable.
