"Lately I've been finishing my races STRONG! Mostly that's due to my Airofit." 

Ironman Competitor

What is Airofit? 

Airofit is a respiratory training system that improves your physical performance, as well as general wellbeing through tested breathing exercises.

Whether you're an athlete, suffer from health issues or simply want to improve your quality of life, Airofit is for you.

Airofit generates resistance on your respiratory muscles. This causes fatigue, which is then compensated by muscle tissue growth, making your breathing muscles faster, stronger and more efficient - just like any other muscle group.

Maintain control
despite fatigue 

Airofit helps strengthen your diaphragm so you can breathe more effectively and get more oxygen even in the riding position, which usually would limit the lung capacity dramatically.

Better endurance
during long races

By training the flexibility of the diaphragm and thorax joints, you increase your vital capacity. You can inhale more air at once, reduce breathing rate and preserve energy - especially during swimming.

Perform when it
counts the most

 Boosts your anaerobic threshold and prolong the period you can perform at maximum power output, giving you the crucial competitive edge during high intensity performance.

Airofit is for triathletes,
as well as everyone else

Airofit is for anyone who is interested in improving their physical performance, health or general wellbeing - regardless of age or current fitness level. You don't have to be a professional athlete to use our system.

Many singers use it to improve their lung capacity and even people who suffer from asthma and COPD benefit greatly from daily breathing training with Airofit.

If you have ever run out of breath, Airofit is for you.

Used separately from other physical activity 

Airofit is designed to be used separately from training and other physical activity. This means that you can use Airofit in any free moment - before bed, at work, after a gym session or whatever suits you best. And it only takes 3-5 minutes a day.

Airofit PRO™ 

Until now measurable breath training was only available to the highest level athletes in a laboratory environment.

Airofit brings the advantages of breath training out of the lab and into your hands. Olympians and World Champions are using Airofit as a daily part of their training regimen and seeing incredible results.

Simple to use - Airofit is easy to add to your training protocol. You only need to use it 8-10 minutes per day to get incredible results.

Virtual Breathing Coach

Airofit has combined the best respiratory training with the latest technology.

The app acts as a virtual breathing coach, giving you live feedback and ensuring all exercises are performed correctly.

The app also allows you to track your training in real-time providing a personal dashboard to monitor your progress over time.

Airofit measures your current lung function.

Training without data is guessing! 

Triathlon is at a modern-day crossroads. Those not embracing and mastering data-driven training will inevitably get left behind by their data-savvy competitors.

Respiratory data on your vital lung capacity - respiratory strength - breath control - aerobic and anaerobic thresholds just got added to the game.

Know your numbers - train to win!

"Training with Airofit gives athletes larger vital lung capacity, stronger breathing muscles, and higher anaerobic tolerance. It´s not my opinion, it's a medical fact."

Professor at Pavia University, Scientist, Former World Champion in Freediving

"Airofit's ability to measure and track respiratory training has been a game changer. Airofit makes training simple and provides the feedback needed to validate and guide people to improved performance."

Master Airofit Instructor, Degree in Public Health, Epidemiology and Nutritional Sciences

"After training only 3 weeks with Airofit, I increased my top speed from 60 to 67 km/h. It meant that instead of losing the sprints, I began winning them, and it made me a National Champion!"
