Learning how to breathe while swimming freestyle is often more difficult than learning the arm movement itself. You may feel comfortable moving through the water until you turn your head for air, lose your balance and suddenly feel as though you cannot breathe quickly enough.
Efficient freestyle breathing is not about taking the biggest possible breath. It comes from exhaling while your face is underwater, rotating your head with your body and taking a short, relaxed breath without interrupting your stroke.
Once these movements begin working together, breathing becomes part of your swimming rhythm rather than something that stops it. This guide explains the complete technique, the most common mistakes and the drills that can help you breathe more comfortably in both the pool and open water.
How should you breathe during freestyle?
Exhale steadily while your face is underwater. As your body rotates, turn your head to the side, keep the lower goggle close to the surface and take a quick breath through your mouth. Return your face to the water before the recovering hand enters in front of you.
Why freestyle breathing feels difficult
Breathing on land happens automatically. You can inhale and exhale whenever you need to without coordinating the breath with another movement. Freestyle swimming is different because your face spends most of the stroke underwater.
You only have a short window in which to inhale. That breath must also be coordinated with your body rotation, arm recovery, kick and forward movement.
Several breathing problems can therefore occur at the same time:
- You hold your breath while your face is underwater.
- You try to exhale and inhale during the same short breathing window.
- You lift your head instead of rotating it to the side.
- Your hips and legs sink when your head moves out of position.
- You turn your face too far and look toward the ceiling.
- You begin the breath too late in the stroke.
- You swim faster than your current breathing technique can support.
These mistakes increase drag and energy consumption. The harder you work, the more oxygen you require, which can make the breathing problem feel progressively worse.
The goal is to create a calm and repeatable pattern. You should not need to fight the water every time you take a breath.
How to breathe while swimming freestyle
Keep your head in a neutral position
Look mostly downward when your face is in the water. Your head should remain aligned with your spine rather than being lifted toward the end of the pool.
Some swimmers look directly beneath themselves, while others look slightly forward. The important point is that your neck remains relaxed and your head does not rise above its natural position.
A neutral head position helps keep your hips close to the surface and reduces frontal resistance.
Begin exhaling underwater
Start releasing air shortly after your face returns to the water. You can exhale through your nose, your mouth or a combination of both.
The exhalation should be controlled rather than explosive. You can release slightly more air immediately before turning to breathe, but you should not hold a full breath throughout the stroke.
Most of the previous breath should already be gone before your mouth reaches the surface.
Rotate your shoulders and hips
Your body should naturally rotate from side to side during freestyle. Use this movement to help bring your mouth toward the surface.
Do not keep your chest completely flat while turning only your neck. Your head should initially move with your shoulders before making a small additional rotation to clear your mouth from the water.
The rotation should remain controlled. Excessive rolling can disrupt your kick and cause your legs to cross over.
Keep the lower goggle close to the water
A useful technique cue is to keep the lower goggle beneath or very close to the surface while the upper goggle clears the water.
You do not need to turn your entire face upward. Your mouth only needs to reach the small pocket of air created beside your head as you move forward.
The lower goggle may not remain completely submerged in every situation. The cue is mainly intended to prevent you from lifting or over-rotating your head.
Take a quick breath through your mouth
Inhale through your mouth during the short breathing window. The breath should be quick but relaxed.
You do not need to completely fill your lungs on every breath. Trying to take the largest possible inhalation can create unnecessary tension in your jaw, neck and shoulders.
Take enough air to support the next strokes and then continue the movement.
Return your face before the hand enters
Begin returning your face to the water as the recovering arm moves forward. Your head should return to neutral before or as the hand enters the water.
Avoid following the recovering arm with your eyes. Turn your head back toward the bottom of the pool while your body completes its rotation.
Once your face is submerged, begin the next controlled exhalation.
Exhale underwater instead of holding your breath
Holding your breath is one of the most common reasons swimmers feel breathless. Many beginners instinctively close their mouth and wait until they turn to the side before releasing their air.
This leaves very little time to complete two separate actions:
- Exhale the used air from the previous breath.
- Inhale enough fresh air for the next strokes.
The breathing window becomes rushed, and the swimmer often takes an incomplete breath before the face must return to the water.
Holding your breath can also increase the feeling of air hunger. Even when you have inhaled enough oxygen, the build-up of carbon dioxide can make you feel as though you urgently need another breath.
Bubbles underwater, breath to the side
You should see or feel a controlled stream of bubbles while your face is submerged. By the time you rotate to the side, your lungs should be ready to receive the next breath.
You do not need to force every last bit of air out immediately. Completely emptying your lungs too early can also make you feel desperate to breathe. Aim for a controlled release that finishes shortly before your mouth reaches the surface.
Rotate your head instead of lifting it
When you lift your head to breathe, your upper body rises while your hips and legs tend to sink. This increases frontal resistance and makes every stroke more demanding.
Efficient breathing is created through rotation rather than elevation. Your head should travel around the long axis of your body while remaining close to the surface.
Rotating to breathe
- Your head remains aligned with your spine.
- Body rotation helps expose your mouth.
- The lower goggle stays close to the water.
- The breath is taken beside your body.
- Your hips remain close to the surface.
Lifting to breathe
- Your head moves forward and upward.
- Both goggles rise far above the surface.
- You look across the pool or toward the ceiling.
- Your lead arm presses downward for support.
- Your hips and legs drop deeper into the water.
Imagine that a straight line runs from the top of your head through your spine. Rotate around this line rather than bending your neck upward.
When should you breathe during the freestyle stroke?
Correct timing makes the breathing window feel longer and more controlled. Begin rotating toward the breathing side as the arm on that side completes its underwater push and prepares to leave the water.
The correct movement sequence
When breathing to your right side, the stroke normally follows this sequence:
- Your left arm remains extended or begins its catch in front of you.
- Your right arm finishes pushing water behind your body.
- Your shoulders and hips rotate toward the right.
- Your head rotates with your body.
- You inhale while your right arm recovers over the water.
- Your face returns before your right hand enters or extends forward.
A common mistake is turning too late. When the recovering arm has already passed your shoulder before you begin to breathe, the available breathing window becomes extremely short.
Another mistake is pressing the lead arm downward to lift your head. Try to keep the lead arm stable in front of you while you rotate. This gives your body support without creating unnecessary vertical movement.
Do not wait for your arm to reach your head
Your head should begin rotating before the recovering hand passes your face. Start the movement as the breathing-side arm finishes its underwater push.
How often should you breathe?
There is no single breathing pattern that is ideal for every swimmer, speed or situation. You should breathe frequently enough to receive the oxygen you need while maintaining good technique.
| Breathing pattern | How it works | When it can be useful |
|---|---|---|
| Every 2 strokes | You repeatedly breathe to the same side. | Steady swimming, harder efforts and races where oxygen demand is high. |
| Every 3 strokes | You alternate between the left and right sides. | Technique practice, balanced rotation and comfortable aerobic swimming. |
| Every 4 strokes | You breathe to the same side with a longer interval. | Controlled drills and easy swimming for experienced swimmers. |
| Mixed pattern | You change between two-, three- or four-stroke patterns. | Adapting to fatigue, speed, waves, sunlight and nearby swimmers. |
Breathing every three strokes is commonly called bilateral breathing because it naturally alternates between both sides. It can help you become comfortable breathing left and right, but it is not necessary during every length.
Breathing every two strokes is not poor technique. It provides more frequent access to oxygen and is commonly used during harder swimming. Many triathletes primarily breathe every two strokes while still practising the ability to breathe to either side.
Breathing comfortably to both sides
Bilateral breathing does not have to mean breathing every three strokes. You can breathe to the right for one length and to the left for the next, or use mixed patterns such as 3-2-3-2. The objective is to remain capable of breathing on either side.
Should you breathe through your nose or mouth?
Inhale through your mouth
Your mouth allows you to take in air quickly during the short period when your face is turned to the side.
Exhale through your nose, mouth or both
Exhaling partly through your nose can help keep water out of the nasal passages, while your mouth makes it easier to release a larger amount of air.
Many swimmers naturally use a combination of nasal and mouth exhalation. The exact balance is less important than making sure you release the air before turning to inhale.
Freestyle breathing drills
Breathing drills allow you to practise individual parts of the movement before combining them during continuous freestyle. Perform each drill slowly and prioritise control rather than speed.
Wall breathing drill
Hold the side of the pool with both hands. Place your face in the water and exhale steadily until you see bubbles. Rotate your head to the side, inhale through your mouth and return your face to the water.
Focus: Separating underwater exhalation from above-water inhalation.
Side-kick drill
Kick gently while lying on one side. Keep your lower arm extended and your upper arm resting beside your body. Practise rotating your face between a downward position and a side-breathing position.
Focus: Keeping your head low while breathing.
Six-kick switch
Kick on one side for approximately six kicks, take one stroke and rotate to the opposite side. Breathe during the rotation when required.
Focus: Connecting body rotation, stroke timing and breathing.
Single-arm freestyle
Swim using one arm while the other remains extended in front of you or rests beside your body. Breathe toward the working arm and concentrate on turning with your shoulder.
Focus: Timing the breath with the arm recovery.
Catch-up freestyle
Keep one arm extended until the other hand reaches the front. Use the slower rhythm to practise breathing while maintaining support from your lead arm.
Focus: Preventing the lead arm from collapsing during the breath.
Fingertip-drag freestyle
Lightly drag your fingertips across the surface during the arm recovery. Breathe early enough that your face returns to the water before the recovering hand moves forward.
Focus: Relaxed recovery and correct breathing timing.
Use fins while learning the movement
Swimming fins can provide additional propulsion and help your body remain close to the surface. This gives you more time to concentrate on your head position and breathing timing. Gradually repeat the same drills without fins as your technique improves.

Common freestyle breathing mistakes
| Mistake | What happens | How to correct it |
|---|---|---|
| Holding your breath | You feel increasingly desperate for air and must exhale and inhale at the surface. | Release bubbles gradually while your face is underwater. |
| Lifting your head | Your hips sink and drag increases. | Rotate to the side and keep the lower goggle close to the water. |
| Turning too far | You look upward and lose your balance in the water. | Rotate only until your mouth clears the surface. |
| Breathing too late | The recovering arm reaches the front before you complete the breath. | Begin rotating as the breathing-side arm finishes its underwater push. |
| Pressing the lead arm down | Your front support disappears and your head rises. | Keep your lead arm extended while rotating around your body axis. |
| Taking an oversized breath | Your jaw, neck and shoulders become tense. | Take a quick, relaxed breath rather than trying to fill your lungs completely. |
| Swimming too quickly | Your oxygen demand exceeds your ability to maintain the breathing rhythm. | Slow down until you can control your exhalation and head position. |
| Only breathing to one side | You may struggle when waves, sunlight or another swimmer blocks your preferred side. | Include short repetitions breathing toward your less comfortable side. |
How to avoid feeling out of breath
Feeling breathless does not always mean that you lack cardiovascular fitness. It is frequently caused by tension, breath-holding or swimming faster than your current technique can support.
- Swim more slowly than you think is necessary.
- Use short repetitions of 25 or 50 metres.
- Rest long enough to regain calm breathing between repetitions.
- Practise exhaling while holding the side of the pool.
- Use fins temporarily if your legs sink during breathing drills.
- Breathe every two strokes if every three strokes leaves you short of air.
- Stop the repetition when your technique begins to collapse.
Trying to force yourself through longer distances with poor breathing technique can reinforce the movement patterns you are attempting to correct. Increase the distance gradually as the breathing rhythm becomes more reliable.
Avoid prolonged underwater breath-holding
Do not practise extended underwater swimming or repeated breath-holding alone. Breathing drills should improve technique and rhythm rather than test how long you can remain underwater.
Breathing while swimming in open water
Open-water breathing uses the same fundamental technique as pool swimming, but waves, wind, sunlight and nearby athletes can affect which side is most practical.
Triathletes should therefore learn to breathe comfortably on both sides, even if they continue using one preferred side during most of their swimming.
Breathe away from approaching water
If waves repeatedly approach from one side, breathing toward the opposite side can reduce the risk of swallowing water.
Use other swimmers as a reference
Breathing toward a nearby swimmer can help you monitor their position, although you may choose the opposite side when there is heavy splashing.
Change sides when visibility is poor
A low sun can make one breathing side uncomfortable. Being able to breathe on either side gives you more flexibility during a race.
Separate sighting from breathing
Normal freestyle breathing happens to the side. Sighting requires briefly looking forward to check your direction.
A simple sighting sequence
- Press slightly downward with your lead arm and lift your eyes just above the surface.
- Check your direction quickly.
- Rotate immediately to the side and take a normal breath.
- Return your face to the water and resume your regular stroke.
Trying to look forward and inhale at the same time often causes your head to rise too far. Keep the sighting movement brief and use the following side rotation for the breath.
Read our open-water swimming guide for more advice on sighting, navigation, drafting and swimming confidently outside the pool.
How breathing changes with swimming intensity
Your breathing pattern may change as your swimming speed increases.
Every two or three strokes
Easy swimming is a good opportunity to practise both sides and concentrate on smooth rotation and controlled exhalation.
More frequent breathing
Breathing every two strokes often provides the oxygen required to sustain a harder effort. The breath should remain quick and integrated into the stroke.
Reduced breathing frequency
Experienced swimmers may take fewer breaths during very short sprints, but this should not be copied during normal endurance training or longer triathlon swims.
For triathlon training, there is normally little benefit in deliberately restricting your breathing for long periods. Your goal is to swim efficiently while receiving enough oxygen to maintain the effort and prepare for the bike and run.
How long does it take to improve freestyle breathing?
Some swimmers notice an improvement after a few focused sessions, while others need several weeks before the movement begins to feel automatic.
Progress depends on more than breathing alone. Body position, balance, rotation, arm timing and kick efficiency all affect how easily your mouth reaches the surface.
First sessions
Focus on exhaling underwater and completing relaxed 25-metre repetitions.
Developing consistency
Practise rotating without lifting your head and begin combining drills with normal freestyle.
Increasing distance
Extend repetitions to 50 and 100 metres while maintaining the same breathing rhythm.
Open-water adaptation
Practise breathing on both sides and combine normal breathing with controlled sighting.
Practising for a short period during every swim is usually more effective than dedicating one entire session to breathing and then ignoring it for several weeks.
You can also ask a coach or training partner to record a short video from the side. Head lifting, late breathing and excessive rotation are often easier to identify on video than they are to feel while swimming.
Frequently asked questions
Should I breathe every two or three strokes?
Use the pattern that allows you to maintain relaxed and efficient swimming. Breathing every two strokes provides more frequent oxygen, while every three strokes naturally alternates sides. Many swimmers use both patterns depending on the intensity and situation.
Why do I run out of breath after one length?
You may be holding your breath underwater, swimming too quickly or using unnecessary energy because your head and hips are out of position. Slow down, exhale continuously and practise shorter repetitions with adequate rest.
Should I breathe through my nose while swimming?
Inhale through your mouth. Underwater, you can exhale through your nose, your mouth or both. A partial nasal exhalation can help prevent water from entering your nose.
Why do I swallow water when breathing?
You may be breathing too late, lifting your head, turning too far or attempting to inhale while your mouth is still too close to the surface. Begin the rotation earlier and keep the breath quick. In open water, breathe away from approaching waves when possible.
Is it bad to breathe only to one side?
Breathing primarily to one side is not necessarily bad, especially during harder swimming. However, learning to breathe on both sides gives you more flexibility and may help you develop more balanced rotation.
Should I completely empty my lungs underwater?
You should release most of the used air before turning to breathe, but you do not need to force every last bit of air out early. Use a controlled exhalation that allows you to inhale comfortably at the surface.
Can I use a nose clip for freestyle swimming?
You can use a nose clip, but most freestyle swimmers learn to control water by exhaling through the nose. A nose clip may be useful in certain situations, although it removes the option of nasal exhalation.
Final thoughts
Efficient freestyle breathing is built around a few fundamental actions: exhale underwater, rotate with your body, keep your head close to the surface and take a quick breath without interrupting the stroke.
Do not measure progress only by how far you can swim without stopping. Pay attention to whether you remain relaxed, maintain your body position and repeat the same breathing movement from one length to the next.
Start with short repetitions, use drills to isolate the movement and gradually increase the distance as your technique becomes more automatic. For a broader explanation of the complete stroke, read our freestyle swimming guide.
