Increased pace
Airofit strengthens your diaphragm so you can breathe more effectively during a high-paced activity, reducing heart rate and breathlessness.
Better endurance
Airofit increases your accessible lung capacity so you can inhale more air at once, reduce breathing rate and preserve energy.
Longer sprints
High anaerobic threshold prolongs the time you can perform at maximum power output, giving you a competitive edge during sprints.
What is Airofit?
Airofit is a respiratory training system that improves your physical performance, as well as general well-being through tested breathing exercises.

What our customers say

See what an ultra-marathon runner has to say about Airofit:
“The bedrock of endurance sports is efficient recovery, and Airofit is my key to unlocking another level of muscle revival. Breathing fuels my body with the energy it requires to repair itself, and through training my respiratory muscles my strength is restored more expertly and expansively than ever before.”

Used separately from other physical activity

And it only takes 5-10 minutes a day.
“Diaphragmatic breathing improves focus, lowers blood pressure, facilitates athletic performance and recovery, helps you sleep better.”

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

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.
