30% increase of breathing strength
in 4-6 weeks
We treat breathing as an ecosystem.
The science of RMT
Think of Respiratory Muscle Training (RMT) as strength training for your breathing muscles. Controlled resistance challenges your diaphragm and other respiratory muscles, helping them grow stronger and more efficient over time.
But Airofit takes RMT to the next level. Our system helps you understand, measure and improve your breathing.
20% more lung capacity in 4-6 weeks.
Your lungs are like a fuel tank. Most people use only a fraction of it because their breathing muscles aren't strong enough to pull in more.
Breath training strengthens your diaphragm and breathing muscles so they can pull down deeper and expand wider, giving you instant access to how much oxygen your body actually needs.
Illustrative — your starting point is measured on your first session.
