How to Breathe Properly While Swimming: The Secret to Swimming Longer Without Getting Tired
It might sound counterintuitive, but for many people new to swimming—or even intermediate athletes—the biggest limiter isn’t muscle fatigue or poor kick technique. It’s breathing.
Mastering your breath in the water is arguably the most fundamental piece to unlocking endurance, efficiency, and enjoyment in your swim sessions. And after watching a recent video breakdown by a swimming coach with over 19 years of experience, I realized how often we overlook this simple truth: if you can’t regulate your breathing, your body will never relax enough to go the distance.
Key Takeaways
- Regulating your breath is the foundation to endurance—inhale above water, exhale below, and never aim to fill your lungs to 100% capacity.
- Sync your breath with stroke and rotation—turn your head as a natural part of your movement, not as an extra step.
- Avoid going too long between breaths—start with breathing every 2–3 strokes, then explore bilateral breathing.
- Relax your body while swimming—tension wastes energy and raises heart rate.
- Open water? Adapt but don’t abandon the principles. Choppy water may change your positioning, but not your breath control.
Why Most Swimmers Get Tired Too Soon
When I was training for my first Olympic-distance triathlon, there was one thing I dreaded more than cold water: gasping for air halfway through the swim. I figured it was a cardio problem. Maybe I just hadn't trained enough. But no—that wasn't it.
It turns out, I wasn't breathing correctly. Like many beginners, I made three major mistakes:
- I tried to inhale too much air—reaching for 100% lung capacity every breath.
- I held my breath underwater instead of properly exhaling.
- I waited too long between each breath.
The result? Fatigue, rising CO₂ levels, and panic. It wasn’t a fitness issue. It was a technique issue. Like trying to sprint on a treadmill while holding your breath.
How to Fix Your Breathing Technique for More Stamina
Master the Inhale/Exhale Rhythm
This is the core principle of swimming breathing regulation. Let your body find a pattern:
- Inhale when your mouth clears the surface as you rotate—and do not try to fill your lungs completely. Aim for around 70–80% to stay relaxed.
- Exhale slowly and fully through your nose or mouth while underwater. This purges CO₂ and prepares you for your next breath.
Why does this matter? When carbon dioxide builds up in your body, your perceived fatigue increases faster than your actual exertion. Controlled exhalation minimizes CO₂ buildup and prevents muscle fatigue caused by lactic acid accumulation.
Synchronize With Your Stroke and Rotation
If your breathing feels disconnected from the flow of your swimming, it often means you're turning your head too late or too abruptly. As your hand comes forward and your body naturally rotates to the side, that’s your cue to turn your head smoothly for a breath.
Think of your body like a wave, and your breath hitching a ride on its crest. No sharp pivots. No pausing mid-stroke. Just rhythm and timing.
Choose the Right Breathing Pattern for You
Don’t try to force fancy breathing patterns right away. The advice from the video is clear: keep it simple, especially if you're a beginner.
- Start by breathing every 2 strokes.
- Build up to every 3 strokes for bilateral breathing once you're comfortable.
Bilateral breathing (alternating sides) is great for stroke symmetry and open water navigation, but only if you’re not sacrificing oxygen in the process. Prioritize function over form until your breathing feels like second nature.
Relaxation Reduces Heart Rate
A relaxed swimmer is an efficient swimmer. Much like in running or cycling, tension equals inefficiency. Keep your shoulders loose, your body soft, and your movements fluid.
Tightness, especially in your chest and upper back, not only drives up your heart rate but can make breathing shallow and rushed. Think of your body like a seal gliding effortlessly—not a brick fighting to stay afloat.
Open Water Adaptations
It’s true—open water complicates things with unpredictable elements like chop, waves, and glare. But the fundamentals still apply. You just have to make small adaptations:
- Slightly extend your head turn when breathing if waves are blocking your path.
- You may need to sight forward and then breathe—or vice versa—to avoid confusing head movements mid-swim.
The key is to stay calm, stay rhythmic, and never let unpredictability shake your breath pattern.
Final Thought: Breathing Is Not Optional, It’s Foundational
Ever try to meditate while sprinting? Neither have I. But that’s essentially what you're trying to do when you ignore breathing technique in swimming. You wouldn’t overlook breathing in yoga or free diving—so why do we neglect it in the pool?
In my journey from couch potato to age-group triathlete, learning to regulate my breath was the single biggest turning point in my swim progress. It's not flashy. It’s not complicated. But it’s powerful.
The sooner you breathe better, the longer you'll last.
