# How to Breathe so Running Feels EASIER!

Professional triathlete and coach Nicklas Rossner outlines five specific breathing protocols to increase running speed, reduce breathlessness, and accelerate recovery without expending extra effort. By shifting breathing habits before, during, and after a run, runners can significantly enhance their oxygen intake and overall stamina. **Key Points:** - Running struggles in the first few minutes stem from the body operating in a parasympathetic resting state instead of an activated sympathetic state. - Power breaths involve taking 5 to 10 deep nose inhalations followed by forceful exhales while standing still to signal the body that it is time to run. - The feeling of being out of breath during strenuous exercise is caused by a buildup of carbon dioxide in the blood triggering the brain to breathe faster rather than an actual lack of oxygen. - Forceful exhales, performed by blowing out air like blowing out a candle during intense running efforts, help eliminate excess carbon dioxide and restore breath control. - Rhythmic breathing, such as a 3:2 pattern where you inhale for three steps and exhale for two steps, creates a natural flow that reduces fatigue and improves focus. - Diaphragmatic belly breathing ensures that air fills the lower lungs rather than just the chest, maximizing oxygen intake and preventing panic attacks. - Box breathing, consisting of a four-second inhale, four-second hold, four-second exhale, and four-second hold, activates the parasympathetic nervous system to speed up post-run recovery. ![Screenshot at 00:19: The five distinct breathing protocols outlined by Nicklas Rossner to improve running performance immediately.](https://ss.rapidrecap.app/screens/pxn34Lx3CYY/00-00-19.jpg) **Context:** Professional triathlete and running coach Nicklas Rossner spent ten years training and working with hundreds of runners before discovering that many exhaustion issues are rooted in poor breathing techniques rather than poor physical conditioning. ## Detailed Analysis Many runners hit a wall at the start of a workout or feel out of breath prematurely because they misunderstand how their nervous system and respiratory mechanics function. To solve this, Nicklas Rossner presents five specific breathing protocols. The first protocol uses power breaths before running to transition the body from a parasympathetic rest state into a sympathetic fight-or-flight state. The second protocol explains that breathlessness is actually caused by carbon dioxide buildup, which can be managed during a run by using forceful exhales to clear out CO2. The third protocol introduces rhythmic step breathing, specifically a 3:2 pattern of three steps inhaling and two steps exhaling, to maintain a steady cadence. The fourth protocol emphasizes diaphragmatic belly breathing instead of shallow chest breathing to expand the lungs fully. Finally, the fifth protocol utilizes box breathing immediately after a run to stimulate the parasympathetic nervous system, lower the heart rate, and accelerate recovery. ### Protocol 1: Sympathetic Activation Activating the sympathetic nervous system before starting a run prevents the uncomfortable sluggish wall runners typically experience in the first few minutes. - The body operates between a parasympathetic rest-and-digest state and a sympathetic flight-or-fight state. - Starting a run directly from a parasympathetic state causes a mismatch between body readiness and physical demand. - Perform power breaths by standing up straight, taking a deep controlled breath through the nose, and exhaling forcefully. - Repeat this breathing sequence five to ten times to signal the body that it is time to exert effort. ![Screenshot at 01:50: Demonstrating the deep nose inhalation used during the power breath warmup.](https://ss.rapidrecap.app/screens/pxn34Lx3CYY/00-01-50.jpg) ### Protocol 2: The Forceful Exhale Managing breathlessness during a run requires expelling carbon dioxide efficiently rather than trying to inhale more oxygen. - The sensation of running out of breath is caused by rising carbon dioxide levels in the blood, which triggers the brain to demand faster breathing. - Hyperventilating by trying to breathe in harder only worsens the situation and forces runners to slow down. - Execute forceful exhales when pushing the pace by blowing out air firmly as if blowing out a candle. - This intentional exhale clears out excess carbon dioxide and helps regain control over respiratory rhythm quickly. ![Screenshot at 03:20: Showing the forceful exhale technique used to clear carbon dioxide during high-intensity running intervals.](https://ss.rapidrecap.app/screens/pxn34Lx3CYY/00-03-20.jpg) ### Protocol 3: The Rhythmic Step Syncing breathing patterns with running strides creates a natural flow that reduces effort and keeps focus sharp. - Elite runners maintain rhythmic breathing tied directly to their stride rather than breathing randomly. - A reliable pattern is the 3:2 rhythm, where runners inhale for three steps and exhale for two steps. - This pattern is generally considered the easiest to maintain for most athletes, though individuals can adapt the ratio. - Maintaining a consistent breathing rhythm makes it much easier to sustain pace over long distances. ![Screenshot at 04:46: Explaining the 3:2 step-to-breath cadence pattern used to maintain running rhythm.](https://ss.rapidrecap.app/screens/pxn34Lx3CYY/00-04-46.jpg) ### Protocol 4: The Balloon Shifting from shallow chest breathing to diaphragmatic breathing ensures the lungs receive maximum oxygen capacity. - Shallow chest breathing fills only the top of the lungs and can lead to dizziness and panic-like feelings during hard efforts. - The lungs are anatomically designed to expand all the way down into the belly. - Practice diaphragmatic breathing by placing one hand on the chest and one on the belly, making sure only the belly rises during inhalation. - Visualize the lungs expanding like a balloon to capture more oxygen and run more efficiently. ![Screenshot at 06:09: Placing hands on the chest and belly to practice correct diaphragmatic breathing mechanics.](https://ss.rapidrecap.app/screens/pxn34Lx3CYY/00-06-09.jpg) ### Protocol 5: The Box Breath Post-run recovery can be significantly accelerated by engaging the parasympathetic nervous system through structured breathing. - Post-workout recovery requires lowering the heart rate and breath rate quickly to transition back to a resting state. - After walking for a few minutes following a run, begin box breathing by inhaling through the nose for four seconds. - Hold the breath on top for four seconds, exhale for four seconds, and hold at the bottom for four seconds. - Maintaining this four-second box pattern rapidly calms the mind and speeds up physical recovery. ![Screenshot at 07:55: The four-part box breathing pattern used to trigger the parasympathetic recovery state.](https://ss.rapidrecap.app/screens/pxn34Lx3CYY/00-07-55.jpg)
