Breathing is often a limiting factor in your cycling performance

Cycle icon

Improved endurance

Breathing muscle fatigue during extended exercise causes limb blood vessels to constrict, which compromises blood & oxygen delivery to the muscles. 

Clock icon

Increased pace

Breath-hold exercises train your CO2 tolerance, which optimizes gas exchange and oxygen delivery to the muscles so you can push harder, for longer.

Higher energy levels

Strong breathing muscles allow you to reduce breath rate and heart rate. This allows you to use less energy on breathing itself and more on your limb muscles!

A data-driven approach to improve performance that matters to you!

The Airofit app delivers a personalized training plan based on your unique lung data, age, size, sex, and goal.

Trusted by the World’s best: Partnership with Lotto Soudal

Often we have seen the question – if Airofit works, wouldn’t pros be using it? And the simple answer is, they are and have been for quite a while!

Lotto Soudal has always been outspoken about only partnering up with companies and people that bring real value to their team. After several riders had started their breathing training journeys individually, they requested the team to bring everyone on board and exploit the benefits of better breathing together, as a team.

We could not be more proud of this opportunity and can’t wait to see where this takes us, Airofit and Lotto Soudal this season, and beyond!

table of how efficient airofit training is compared to high intensity cycling interval training

Scientifically proven to be as effective as VO2Max training

Easier, more convenient, and far more time-efficient.

Implementing additional 2 hours of high intensity cycling intervals every week into your current training could improve your cycling performance by 5%.

Alternatively, you can gain the same benefits by using Airofit only 4 minutes a day from the comfort of your home.

Airofit is your virtual breathing coach

All Airofit exercises are developed by industry-leading breathing experts. While Airofit’s resistance training improves your breathing muscle strength, the mobile app teaches you how to use those muscles and how to breathe correctly.

By measuring your lung function, Airofit tailors all exercises to you based on this data, your age, size, gender and the chosen training goal.

Via live feedback and guidance, the app ensures you perform all training correctly and teaches yourself optimal breathing patterns.
