The Science
The principles have been researched and refined for over 60 years. Two systems explain how it works: your blood chemistry, and your nervous system.
Even at 100% blood oxygen, your cells can be under-oxygenated. We want to close that gap.
The Mechanism
Each one is a different view of the same thing: getting more oxygen from less air.
Oxygen Efficiency
More oxygen delivered to your cells from less air. The outcome the whole method points toward, and what improves as you train.
Read more →CO₂ Tolerance
A trained ability to stay calm as CO₂ rises. The higher your tolerance, the more oxygen your blood releases to your cells, and the less air you need.
Read more →The Oxygen Traffic Jam
Your blood can be full of oxygen while your cells stay starved, because the blood won't release it. Breathing training clears the jam.
Read more →Minute Volume
How much air you breathe per minute. As it settles toward healthy values, oxygen delivery rises. Less air in, more oxygen out.
Read more →The Nervous System
Each one is a different view of the same thing: training your nervous system to stay calm under load.
Nervous System
Your heart rate and stress hormones are set by a part of your nervous system that takes no orders. Only the breath can be reached directly.
Read more →Instinctual Response
One breath after every breath-hold shows exactly how it went, straight from your nervous system.
Read more →Stress Detection
The app reads whether you stayed calm or tensed, straight from your breathing. Nothing to wear.
Read more →Pushing Too Hard
Forcing a breath-hold sets off the very stress response the practice is meant to quiet, and cancels the gain it was building.
Read more →Adaptive Intensity
The breath-hold target is not fixed. It starts from your style and level, then adapts round by round to your own score.
Read more →Better oxygen delivery means better cell performance. We train what controls that delivery.
