Winning Happens While You Breathe: How the Isocapnic Changes the Game in MMA, Boxing, and the UFC

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 technique and physiology. The side with more physiological control dictates the pace, the chaos, and […]

Cold Plunge Breathing: How to Use the Isocapnic to Recover Faster, and Build Resilience

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 a recovery ritual. It turns into a scientifically grounded training method that enhances resilience, boosts […]

Respiratory Muscle Trainer: The Complete Guide (And Why Isocapnic Leads the Future of Breathing Performance)

Breathing is the most underrated performance system in the human body. You can have powerful legs, a strong heart, and elite conditioning — but if your respiratory system can’t keep up, everything else suffers. Athletes feel this as the familiar wall of breathlessness. Everyday people feel it as fatigue climbing stairs or during stress. Coaches […]

Conversation with the Roadman Cycling Podcast

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 video version here: Podcast summary and key points For decades, cyclists have obsessed over legs, […]

Improve FTP, VO₂ and Power : Lessons from Elite Cyclists Using Isocapnic Training

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 Isocapnic respiratory training moved the needle for these world-class riders. If athletes at this level […]

How Effective Is Breath Training?

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 effective is breath training? Very! It can be trained, just like muscles in your legs, […]

How to Strengthen Your Lungs and Breathing Muscles

The Smarter Way Forward Most people think of “lung training” as running harder, swimming longer, or holding their breath underwater. While those things certainly challenge your breathing, they don’t systematically strengthen the muscles that actually drive your breath—the diaphragm and accessory muscles. And unlike your biceps or quads, your breathing muscles are primarily endurance fiber. […]

Isocapnic Validation Study

A new study has just been published in the peer-reviewed journal Biology by Tomasz Kowalski of Warsaw, Poland. Keen observers may remember some of his earlier work with speed skaters and triathletes, which confirmed the physiologic benefits of respiratory muscle training. In his most recent publication, he investigates the effects of the BWB (Breathe Way […]

Rethinking Respiratory Limits in Exercise

Review of: Barstow TJ, Murphy K, et al., “Respiratory Limitations during Exercise,” Current Opinion in Physiology, Volume 10, August 2019, pp. 173–179. For decades, we’ve assumed that in healthy individuals, the lungs and respiratory system are “overbuilt”—more than capable of handling the demands of even the most intense workouts. Recent research, however, paints a different picture. Three […]

Athletes, Breathe Stronger, Perform Longer: How To Increase Lung Capacity with Isocapnic

Every athlete knows the feeling of burning lungs when pushing to the limit. That breathless sensation isn’t just discomfort – it’s a performance ceiling. Lung capacity can be the secret ingredient that separates a personal best from an average performance. To go faster or last longer, you don’t just need stronger legs or a bigger […]
