Metabolic Testing
Test — and train with precision.
Every athlete’s physiology is unique — that’s why I don’t guess, I test. Using portable, lab-grade technology, I measure your VO₂max, lactate thresholds, and resting metabolic rate (RMR) to uncover exactly how your body produces and uses energy. This data removes all the guesswork from training, revealing your true endurance zones, fueling needs, and recovery requirements for faster progress.
Whether in the lab or in the field, my on-the-go metabolic testing captures how your body performs in real conditions —so every workout, interval, and recovery day is guided by data, not estimates.
Train smarter, perform stronger, and know with confidence that every session moves you closer to peak performance.
Starting at $150
I help endurance athletes train smarter — not harder — through 1-on-1 coaching and cutting-edge physiological testing. Using VO₂max, metabolic, and threshold data, we design individualized training, fueling, and recovery plans that align with your unique physiology and lifestyle.
Whether you’re a trail runner, cyclist, or mountain athlete, I’ll help you break through plateaus, recover stronger, and perform at your best without adding more hours to your week.
If you’re ready to finally understand your body, optimize your training zones, and see measurable results, this is where science meets performance.

After years of research, coaching Olympic medalists and championship teams, and overcoming my own burnout as an athlete, I realized real progress doesn’t come from doing more — it comes from training smarter. Through individualized 1-on-1 coaching and advanced metabolic and biomechanicall testing, I help trail runners, cyclists, and endurance athletes optimize their physiology, balance their training with life, and perform at their best without sacrificing health or time.
