Fitness Assessment: Your First Step to Smarter Training

Why does it work?

Whether you’re starting an exercise regimen, looking to find your "Zone 2" and VO2max, refining your nutrition demands, or restarting after injury, this test gets you all the data you need. The results provide you with customized, actionable recommendations and training zones based on physiological conditions instead of estimates.

What is a Fitness Assessment?

At our eLab in Mill Valley, our Fitness Assessment uses a clinical-grade metabolic measuring system to analyze VO₂max, anaerobic threshold, FATmax, and training zones. The result? Customized exercise recommendations tailored to your physiology.

What will you walk away with?

  • Key metrics: Training zones, cardiorespiratory fitness, VO₂max, and aerobic power

  • Fuel insights: How your body uses fat vs. carbs and calorie burn at different intensities

  • Economy data: Performance cues for running, cycling, or rowing

  • One-on-one consult: Get a full debrief with an exercise physiologist
