CHANHASSEN, MN – As VO2 max and metabolic health regain attention as critical indicators of fitness, performance and longevity, Life Time (NYSE: LTH) is reinforcing its long-standing leadership in the space with a national rollout of next-generation SpiroFit technology to all of its clubs. A pioneer in bringing VO₂ max and metabolic testing into a club setting in 2005, Life Time is introducing a system that furthers the benchmark for delivering lab-grade metabolic data to its members across North America.
Active metabolic testing shows members how many calories they burn at different heart-rate levels and whether those calories come primarily from fat or carbohydrates. As intensity increases, the body shifts from burning more fat to carbohydrates. Understanding that shift and when it happens helps members know how hard to train, when to push, and how to align workouts with goals like endurance, performance, weight management and overall metabolic health.
“More than 20 years ago, we brought metabolic testing into our clubs because we believed members deserved the same performance insights once reserved for elite athletes,” said Danny King, Director of Performance and Recovery at Life Time. “That belief still drives us today. With SpiroFit, we’re delivering clinical-level insight in a way that fits seamlessly into the club experience and helps members understand how their bodies burn sugar and fat and apply that knowledge across our programs to train smarter and see measurable progress.”
Life Time also integrates these insights directly into its in-club coaching and performance programs. Results inform personalized plans created by Dynamic Personal Trainers and enhance its Signature Group Training offerings such as Ultra Fit, GTX, Alpha and a new HybridXT class, helping members train in the right heart-rate zones, optimize effort and track measurable progress over time.
The SpiroFit mask enhances the experience with a cordless, wearable metabolic testing device that allows members to move naturally on a treadmill, rower or other equipment while maintaining lab-grade accuracy. Results are delivered quickly and clearly, making advanced metabolic data easier to understand and apply within Life Time’s broader training ecosystem.
“SpiroFit delivers lab-grade metabolic data with accuracy validated within one to three percent,” said Chad Goldberg, Sports Scientist at SpiroFit. “That precision gives Life Time members a reliable picture of how their bodies use oxygen and fuel—insights they can trust as they train.”
Using SpiroFit technology, Life Time assessments generate a personalized five-zone training profile that supports smarter workouts and measurable progress—whether members are focused on performance, weight management, or long-term health.
SpiroFit testing first debuted in select Minnesota Life Time clubs in late 2025 and has since been rolled out to all of the company’s athletic country clubs across North America.
