Longevity & AgingLife Time Rolls Out VO2 Max Testing Nationwide to Track Your Biological Aging
Life Time fitness clubs are rolling out SpiroFit metabolic testing across North America, making VO₂ max measurement accessible to everyday gym members. Previously confined to elite sports labs, this wearable mask-based system captures how your body uses oxygen and burns fat versus carbohydrates during exercise. Results are translated into a five-zone training profile, helping users train smarter rather than harder. VO₂ max is now recognized as one of the strongest predictors of cardiovascular health, disease resilience, and long-term healthspan. By democratizing this once-exclusive testing, Life Time is positioning metabolic data as a practical tool for anyone serious about optimizing how they age — not just competitive athletes.
