Causality over interpretation
Training and performance are approached through physiological cause–effect relationships and mechanisms — not opinions, philosophies, or heuristics. Understanding why something works comes before deciding what to do.
Reverse Engineering Performance
A 4-Day Hands-on Camp on Physiology, Diagnostics, Nutrition, and Training Adaptation
Most coaching education focuses on methods, experience, and interpretation. Reverse Engineering Performance focuses on cause–effect.
This 4-day immersive camp teaches how performance emerges from physiology — and how training and nutrition adaptations follow from it.
By the end of the camp, you will be able to assess an athlete’s metabolic profile and, based on the data, immediately make physiology-informed decisions on how to design training and nutrition strategies that improve performance.
No opinions. No training philosophies. Just scientific causal relationships and physiological mechanisms.

The camp
This exclusive clinic includes:
Workshops: Get hands-on experience on physiological testing, creating a 360° physiological athletic profile across different sports. Learn how to measure and analyze key performance metrics such as VO2max, VLamax, FatMax, substrate utilization, running economy and more.
Masterclasses: Each day, dive deep into key topics like energy metabolism, athlete profiling, and nutrition strategies for endurance athletes. Gain expert knowledge to apply directly to your coaching and lab practice.
Mentorship: Work closely with our expert to develop personalized training plans using real athletes’ data. This is your chance to refine your skills and confidently apply the knowledge gained in workshops and masterclasses.
Four days, 24 sessions
By the numbers
10
sessions, including; energy metabolism, fat combustion, aerobic & anaerobic capacity, lactate as a fuel.
7
sessions on adaptation to training: phenotype-based, reasoning behind low-intensity high volume vs. high-intensity interval training, etc.
2
sessions on metabolic testing (VO2, lactate sampling, running economy, VLamax, VO2max, and thresholds, using the most trusted testing devices).
5
sessions on interpretation and application of the results of metabolic testing (training zones, how to identify performance limiting factors, nutrition to maximize training adaptation).
Hands-on
Highlights that make the difference
- Hands-on learning with athletes and coaches in the field. This means testing athletes, applying test data to training, and understanding the unique needs of each athlete. True insiders look at world-class training and testing.
- Become an expert in metabolic testing. You will conduct lactate and VO2 testing: at the running track, and on the road.
- Learn how to interpret and apply metabolic data to inform training programs with the highest efficacy.
- What it feels like to be part of this camp. From basing training programs on experience and philosophy — to mastering the mechanisms that drive performance.

Why this camp
Why This Camp Stands Out
No philosophies. No opinions. No generic frameworks.
Theory and practice — fully integrated
This camp connects theory and practice in a continuous loop. Physiological concepts are immediately linked to real testing, data, interpretation, and application. Diagnostics, analysis, and training design are learned as one coherent process — not as isolated disciplines.
Applied physiology, not textbook science
The focus is strictly on applied exercise physiology.Only concepts that are relevant for performance, diagnostics, and training adaptation are taught — always grounded in current science, but translated into practical, usable understanding rather than academic detail.
Interactive learning, not frontal teaching
Learning happens through interaction.Participants work with real physiological profiles and interactive athlete models, engage in breakout groups, discussions, and Q&A sessions. This is not a lecture-only based format, but an environment designed for deep understanding and skill development.
A learning environment of experienced practitioners
The camp brings together endurance coaches, performance practitioners, and scientists with diverse backgrounds and experience levels. Learning happens not only from the content, but through shared discussion, comparison, and exchange across disciplines.
