Six Months, Built on Your Data
The O2Max VO2 Max Optimization Program starts with a full Metabolic & Respiratory Health Assessment. Your results set your training zones and show which systems to focus on: oxygen delivery, fuel use, breathing or recovery.
From there, you follow a structured six-month program and retest along the way, so you can see exactly what is changing.
