Testing that explains what your training has been missing
The Performance and Recovery Lab is designed to replace guessing with real numbers you can use. We measure how your body produces energy, how efficiently you use oxygen, and where fatigue begins to ramp up. That means you stop relying on general formulas and start training based on your physiology.
This is not just a “test and done” appointment. The value is in turning the results into direction: what intensity you should train at, what sessions will move the needle, and how to align fueling and recovery so your body adapts instead of stalling. Whether your goal is better endurance, better body composition, or simply knowing where you stand, this gives you a clear baseline and a path to measurable improvement.
Actionable insight
Get real data on how your body performs at different intensities, not just estimates from a watch.
Better training targets
Know your exact training zones so every workout has a clear purpose and measurable impact.
Nutrition and recovery direction
Understand your metabolic needs to fuel and recover properly, not guess based on generic advice.
- What we test
The 3 core tests that shape your plan
Each test answers a different “why” behind performance and progress. Some people need metabolism clarity, others need endurance zones, and many benefit from combining tests into a package. Below are the core assessments offered in the lab and what they reveal, so you can choose the option that matches your goal.
- Resting Metabolic Rate measurement
- Know exactly how many calories you burn at rest
- Peak oxygen capacity during max effort
- Defines your aerobic fitness ceiling
- Find the intensity where lactate builds faster than you can clear it
- Sets your most important training zones
- Who This Helps Most
Built for people who want clarity, not confusion
