Once you've mastered basic breathing, refining your technique will help you swim longer distances with less effort and fatigue. Efficient breathing is the difference between gasping after 50 meters and swimming 500 meters comfortably.
The Problem with Poor Breathing
Common breathing issues that cause fatigue:
- Holding your breath between breaths
- Lifting your head too high
- Not fully exhaling
- Irregular breathing rhythm
- Breathing too frequently or infrequently
Continuous Exhalation
The single most important breathing technique.
Why It Matters
When you hold your breath:
- CO2 builds up in your lungs
- Creates the urge to gasp
- Increases heart rate
- Causes panic and fatigue
How to Do It
Exhale the entire time your face is in the water:
- Begin exhaling immediately after inhaling
- Blow bubbles continuously through your nose
- Exhale slowly and steadily (not all at once)
- By the time you turn to breathe, your lungs are empty
- Inhale fresh air quickly
Practice: Swim 25 meters focusing only on humming underwater the entire time.
Bilateral Breathing in Freestyle
Breathing on both sides has major benefits.
Why Breathe Bilaterally?
- Balanced stroke: Prevents lopsided technique
- Better awareness: See both sides of the pool
- Versatility: Handle sun, waves, or competitors on either side
- Symmetry: Develops even muscle development
Breathing Patterns
Every 3 strokes (most common):
- Right, left, right → breathe right
- Left, right, left → breathe left
- Alternates sides each breath
Every 5 strokes (advanced):
- More breaths on one side
- Good for races or when you need more air
Every 2 strokes:
- Same side every time
- Easier but creates imbalance
Learning Bilateral Breathing
Week 1: Alternate by length
- Breathe right side for one length
- Breathe left side for the next length
Week 2: Alternate every 50 meters
- Practice breathing every 3 strokes
- Focus on smooth rotation both ways
Week 3+: Breathe every 3 strokes all the time
- Make it your default pattern
- It becomes natural with practice
Head Position and Rotation
Small adjustments make huge differences in efficiency.
Proper Head Position
- Look down: Not forward
- Neutral spine: Head aligned with your body
- Waterline: At your hairline or goggles
- Still head: Move as little as possible
Think: Your head is an extension of your spine, not separate.
Breathing Rotation
Common mistake: Lifting your head forward to breathe.
Correct technique:
- Rotate your head to the side
- Keep one goggle in the water
- Create a bow wave that gives you an air pocket
- Breathe in the trough created by your head
- Rotate back smoothly
Drill: Swim with one arm, practice rotating to breathe while keeping bottom goggle underwater.
Breathing Rhythm and Timing
Consistency is key to efficient breathing.
Find Your Rhythm
- Sprint distances (50m): Every 4-5 strokes or hold breath
- Middle distance (100-200m): Every 2-3 strokes
- Long distance (400m+): Every 2-3 strokes consistently
Matching Effort to Breathing
Easy swimming: Breathe every 3-5 strokes Moderate pace: Breathe every 2-3 strokes Hard effort: Breathe every 2 strokes or as needed
Important: Never sacrifice breathing for speed. Getting enough oxygen is more important than a perfect pattern.
Breathing in Other Strokes
Backstroke
- Your face is always up—breathe anytime
- Still maintain a rhythm (inhale on one arm, exhale on the other)
- Don't hold your breath
Breaststroke
- Breathe on every stroke
- Quick breath during arm recovery
- Exhale during the glide phase
Butterfly
- Breathe every stroke (beginners) or every other stroke (advanced)
- Breathe forward as arms recover
- Exhale during the underwater pull
Advanced Breathing Techniques
Hypoxic Training
Swimming with reduced oxygen to build lung capacity.
Example: Breathe every 5, 7, or 9 strokes Benefits: Increases CO2 tolerance, mental toughness Warning: Only for experienced swimmers, can cause dizziness
Sample set:
- 4 x 50m breathing every 5 strokes
- Rest 30 seconds between
- Build gradually
Explosive Breathing
Quick, powerful exhale-inhale.
How to practice:
- Exhale forcefully through mouth and nose together
- Inhale immediately and powerfully
- Creates a explosive "huff" sound
- Used in sprint swimming
Common Breathing Problems & Fixes
Running Out of Air
Problem: Feel like you can't get enough oxygen Causes:
- Swimming too fast for fitness level
- Not exhaling fully underwater
- Breathing too infrequently
Fix:
- Slow down your pace
- Focus on full exhalation
- Breathe every 2 strokes until fitness improves
Swallowing Water
Problem: Getting water in your mouth when breathing Causes:
- Lifting head too early or too late
- Mouth too low in the water
- Not timing with body rotation
Fix:
- Rotate more fully
- Open mouth in the air pocket behind your head
- Practice timing on drills
Neck Pain When Breathing
Problem: Neck hurts after swimming Causes:
- Twisting head too far
- Lifting head instead of rotating
- Tension in neck muscles
Fix:
- Rotate your whole body, not just your head
- Keep one goggle in the water
- Relax your neck
Breathing Practice Drills
Side-Kick Breathing Drill
- Kick on your side, bottom arm extended
- Practice breathing without stroking
- Focus on rotation, not lifting
- 25 meters each side
3-3-3 Breathing Progression
- 3 strokes breathing right only
- 3 strokes breathing left only
- 3 strokes bilateral (every 3)
- Repeat the sequence
Golf Drill for Breath Control
- Swim 25 meters
- Count strokes + breaths = score
- Try to lower your score
- Encourages fewer, more efficient breaths
Breathing Pattern Pyramid
- 25m breathe every 3
- 25m breathe every 5
- 25m breathe every 7
- 25m breathe every 5
- 25m breathe every 3
Sample Breathing-Focused Workout
Warm-up:
- 200m easy freestyle, bilateral breathing
Main Set:
- 4 x 50m side-kick breathing drill (alternate sides)
- 4 x 75m breathing pattern (25m every 3, 25m every 5, 25m every 3)
- 6 x 100m bilateral breathing every 3 strokes
Cool-down:
- 100m easy backstroke
Key Takeaways
- Exhale continuously underwater—never hold your breath
- Bilateral breathing creates balanced technique
- Rotate to breathe, don't lift your head
- Find a breathing rhythm that matches your effort
- Practice breathing drills regularly
- Breathing efficiency comes from relaxation and technique
Master efficient breathing and you'll unlock the ability to swim much longer distances comfortably. It's the foundation of endurance swimming!
