What you get
A system built around your performance.
Adaptive Training Plan
A personalised 12-session programme that evolves with your performance. CO₂ tables, O₂ tables, apnea holds, and thoracic stretching — weighted to your exact level.
Guided Live Sessions
Real-time progress ring, phase-by-phase instruction, and haptic cues keep you fully in the zone. Log diaphragmatic contractions to measure your ease ratio.
Technique Unlocks
Earn new breathwork skills as you advance — belly breathing, contraction tracking, and more. Each unlock comes with the science behind it, not just a how-to.
I went from 45 seconds to over 2 minutes in my first phase. The programme just works.
