Life Time has rolled out SpiroFit technology — a cordless wearable metabolic testing device that delivers lab-grade data with accuracy validated within one to three percent. This innovation has been deployed nationally across Life Time’s athletic country clubs.
The SpiroFit technology generates a personalized five-zone training profile that shows members how many calories they burn at different heart rate levels, whether those calories come primarily from fat or carbohydrates, and exactly when the body shifts from fat-burning to carbohydrate-burning as intensity increases. The results from the wearable metabolic testing device are integrated directly into the company's dynamic personal training and signature group training programs, such as Ultra Fit, GTX, Alpha, and HybridXT.
This innovation may benefit someone who has been exercising consistently but not seeing the changes they want in body composition, endurance, or metabolic health.
