Better endurance
during long rides

By training the flexibility of the diaphragm and thorax joints, Airofit increases your vital capacity so you can inhale more air at once, reduce breathing rate and preserve energy.

Lower heart rate
in Zones 4 and 5

Increased respiratory muscle strength and accessible lung capacity has a direct correlation to lowered heart rate, allowing you to push harder, for longer periods of time.

Perform when it
counts the most

Airofit boosts your anaerobic threshold which prolongs the period of time you can perform at maximum power output, giving you the crucial competitive edge during sprints.

Jhonathan Restrepo's post-Covid comeback

After contracting COVID-19 in January 2021, Jhonatan had to deal with post-Covid symptoms that significantly affected his physical performance. Jhonatan could not figure out how to overcome it - until March, when he was introduced to Airofit and our Master breathing coach, Sean Coakley.

In just 11 days, his accessible lung capacity had increased from 4L to 8.1. His measurements were also confirmed in a professional environment in Hospital San Vincente Fundación. Shortly after his improvements, Jhonatan went to win Stage 7's ITT of Tour of Rwanda.

"I use Airofit to improve my breathing performance at the highest level of cycling and it has made a big difference for me! "

Alvaro Hodeg, after winning GP Marcel Kint

Sprinter, climber, TT specialist, GC contender... each stage, each race has a unique profile and demand to be met in order to stand on top of the podium. At the highest cycling levels, marginal gains are the difference between 1st and 2nd place. Airofit can help create that physiological differentiation guiding you to victory!

Quinn Simmons posts massive lung capacity test results before winning Tour of Wallonie

Quinn Simmons, 2019 World Junior Champion, posted impressive lung test numbers after using Airofit for 3 weeks. Quinn was measuring his accessible vital lung capacity of over 9 liters!Shortly after, he went to be victorious in Tour of Wallonie.

Not only for the Pros:

"After 1 week of using Airofit I set a new Functional Threshold Power during a race, whilst matching my previous maximum 20 minute power output for an entire 40 minutes."

Vincenzo Nibali's comeback story

Vincenzo Nibali is known on the world's biggest stages including the Tour de France. But at 34, biology started to catch up with him and he stopped winning races! Like a true champion, he tried everything - high intensity workouts, diet and supplements.

But over 2 years later none of it made enough difference.

For nearly two season, Vincenzo Nibali did everything he could, but failed to get a win. That is, until a friend introduced him to Airofit and it put him back in the race!

He posted this picture of Airofit on Instagram just days before winning the final stage and taking the overall victory at the Giro di Sicilia.

As with age our lung function decreases, breath training can slow down the deterioration or even reverse it!

This is what happened in Nibali's case.

Proven to be as effective as VO2max training:

Easier, more time-efficient and more convenient!

Respiratory muscle training has been proven to be as effective in improving cycling performance as high intensity interval training at VO2max!  Implementing additional 2 hours of high intensity cycling intervals a week into your current training could improve your cycling performance by 5%.

Alternatively, you could gain the same benefits by using Airofit only 4 minutes a day.

What is Airofit? 

Airofit is a respiratory training system that improves your general well-being through tested breathing exercises.

Whether you want more energy, want to sleep better, suffer from health issues or simply want to improve your quality of life, Airofit is for you.

We train your breathing muscles: the diaphragm and intercostals 

Just like any other muscle group, your breathing muscles respond to resistance training - and that is exactly what Airofit does. It’s like taking your diaphragm to the gym.

As the diaphragm is a large, but thin muscle, you can train it rather easily - just 5-10 minutes daily is enough for it to become faster, stronger and more efficient.

As you start training the diaphragm, you can breathe deeper as your lungs get more room to expand, your breathing rate decreases, and so does your heart rate.

How does it work?

The Airofit Breathing Trainer provides adjustable airflow resistance to your respiratory muscles. It measures your breathing volumes and strength and sends data to your Virtual Breathing Coach on your smartphone.

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.

What does the app do?

Airofit mobile app acts as a virtual breathing coach, giving you personalized training program based on your selected focus area, as well as your baseline lung function measurement.

It then considers your data, your age, size and gender to tailor each training session. The app gives you live feedback and ensuring all exercises are performed correctly.

Your training data is stored in your account which gives you an overview of your training progress over time.

Compatible with iOS and Android.

"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

"I have seen several patients completing a successful breathing training program with Airofit that significantly improved their quality of life."


M.D. Medical doctor,
Senior consultant

"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

"For those wanting to get better at running, swimming, cycling, using the Airofit PRO can be the key to getting ahead of the competition."

"It’s perfect for helping freedivers and surfers hold their breath longer, or giving endurance athletes a boost."

[In FR ] "Respiratory muscles develop like any other muscle group, and like them, they respond to resistance training."

"Many athletes notice an improvement in their primary sports in as little as three weeks."

"Getting out of breath is an instant limiter for any workout. But your respiratory muscles can be trained just like your guns."
