Train both inhalation and exhalation at high volume. Build respiratory endurance, feel less gassed and recover faster between hard efforts.
BWB-specific research has been published in Warsaw, with ongoing work at UBC. Duke University physician-researchers have used Isocapnic systems in clinical research and special-operations performance training.
Unlike resistance-only trainers, BWB supports sustained, high-volume training of both inhalation and exhalation. Its calibrated rebreathing circuit recaptures a controlled portion of exhaled air while continuously admitting fresh air to maintain CO₂ and support normal oxygen saturation.
Build the usable volume of air you can move and sustain under load.
Condition demanding ventilation so breathing is less likely to limit repeated hard efforts.
Train powerful, controlled inhalation and exhalation through a greater range of motion.
Use app-guided protocols to challenge CO₂ tolerance, breathing control and recovery between efforts.
The BWB trains inhalation and exhalation at high volume while its calibrated rebreathing circuit helps maintain CO₂ and support normal oxygen saturation.
Guided sessions, progressive programs and pacing tools give every workout a purpose. The app is included with no subscription.
Use the manual, research library and advanced protocols to progress from your first warm-up to sport-specific and advanced training.
The compact mouthpiece system recommended for most athletes and straightforward daily respiratory training.
Nose clips, bags and monitoring tools that support specific protocols and training setups.
