Description
PrO2 Fit measures your aerobic fitness level with a single breath FIT score. While other fitness devices measure what you have done, PrO2 tells you whether it’s working!
Once you have your FIT score, you can use the PrO2 Fit to increase your aerobic fitness level with a workout automatically tailored to your abilities.
Everyone from couch potatoes to olympic athletes can benefit from the PrO2!
