PrO2™ Fit

PrO2™ uses simple, resisted breath-training exercises personalized to your capability.

The PrO2™ Fit measures your aerobic fitness level with a patented single breath FIT score.

Once you have your FIT score, you can use the PrO2 Fit to maintain and increase your aerobic fitness with a workout automatically tailored to your abilities.

The PrO2 technology is backed by over 20 years of research and real-world results in both the medical and sports communities.

When you measure and train, you breathe IN through the device to maximally train your inspiratory muscles. By training these muscles you increase the time to fatigue during aerobic activity. PrO2 training can increase VO2 max up to 10% even in professionally trained athletes.

This training is ideal for maintaining aerobic capacity when a person cannot do their normal aerobic training due to injury or other factors.

The app plots inspiratory pressure against time and displays it real time. Your initial breath is your baseline and then you train against that baseline for 36 breaths with decreasing rest intervals. This training should be thought of as a weightlifting program. Remember, the PrO2 is training your inspiratory MUSCLES not your lungs. Training harder means more benefit.

The on-screen graphs and statistics provide a great motivation during the work out.

We always tell new users - if you aren’t fatigued at the end of the 36 breath work out – you didn’t do it right!
