Learn how runners and triathletes can build respiratory endurance, usable breathing volume, and control without adding more fatigue to the legs.
See how testing identified Cory Wallace’s respiratory limiter, how his recorded FEV1 and FEV6 changed, and how Isocapnic fits his training.
A complete guide to hypercapnic-hypoxic training, simulated altitude, independent BWB research, acute mountain sickness evidence and safety.
Learn how cyclists can train respiratory endurance, breathing volume, and control off the bike without adding more fatigue to the legs.
Compare voluntary isocapnic hyperpnea with resistance breathing trainers for respiratory strength, endurance, CO₂ control, and athletic performance.
If you are using the Isocapnic BWB, or thinking about it, one of the biggest questions is usually this: Where does this fit into my training? That is a fair question. A lot of athletes understand how to think about
Acute mountain sickness (AMS) is the classic tax you pay when you gain altitude faster than your physiology can keep up. Headache, nausea, fatigue, poor sleep, that “my brain is wrapped in cotton” feeling. It is common, it is miserable,
respiratory training during the holidays For many people, the holidays are a strange mix of joy, chaos, indulgence, and good intentions. Training plans get disrupted. Sleep gets shorter. Calories go up. Schedules fill with family, travel, kids’ activities, and the
Exercise has long been celebrated as one of the most potent tools for sharpening the mind. Even a single workout can lift mental clarity, improve focus, and improve the brain’s ability to juggle tasks. But not everyone can access those
Combat sports reward preparation, but they reveal truth. You might enter the cage sharper, stronger, faster, and smarter — but when your body slips into redline, skill becomes inaccessible and strategy fades into instinct. The fight becomes a negotiation between
Cold plunge breathing isn’t just about surviving the shock of icy water — it’s about mastering your body’s most powerful lever for control: your breath. When combined with the Isocapnic Breathe Way Better (BWB) system, cold plunging becomes more than
Learn how respiratory muscle training develops breathing strength, endurance, volume and control, how the main methods differ, and how athletes can progress safely.
Dr. Andrew Sellars sat down for a conversation with Anthony from the Roadman Cycling Podcast to discuss his experience with integrating respiratory training into endurance training protocols. Check out the full podcast in audio form HERE OR Check out the
Elite professional cyclists already train at the edge of human capacity. Their lungs are huge, their hearts powerful, and their muscles efficient. Pushing their performance even a few percent higher is notoriously difficult. Yet a new study shows that adding
Most people never think about training their breathing. It feels automatic — air goes in, air goes out, job done. But for athletes and anyone chasing better fitness or health, the respiratory system can be a hidden limiter. So, how
