Most swimmers assume backstroke breathing takes care of itself. Your face stays above water, so what could go wrong? More than you’d expect. Without a deliberate breathing pattern, CO2 builds up in your bloodstream, your stroke rhythm breaks apart, and your body position suffers. Uncontrolled breathing actually causes more problems in backstroke than most beginners experience in freestyle.
At Rocket Swim Club in Greater Toronto Area, our coaches, former Moldova National Swim Team members trained in Eastern European methodology, correct this issue with new swimmers across the Greater Toronto Area almost every week. The fix is straightforward: a reliable inhale-exhale pattern synced to your arm strokes, a few adjustments for common mistakes, and targeted drills to make the rhythm automatic.
Do you need a breathing pattern for backstroke?
Yes. Without a deliberate pattern, CO2 accumulates in your bloodstream, causing hyperventilation and fatigue. Tying your inhale and exhale to specific arm recoveries keeps gas exchange consistent and prevents your stroke rhythm from breaking down.
The Biggest Misconception About Backstroke Breathing
“Just breathe whenever you want” is the most common advice swimmers hear about backstroke. And it’s wrong. Your body needs a consistent rate of gas exchange to clear CO2 from your bloodstream. When you breathe at random intervals, that exchange becomes irregular. CO2 accumulates faster than your body can expel it, which triggers a hyperventilation response. You start breathing faster and shallower, your stroke tempo becomes erratic, and your body position deteriorates as your core tension drops.
This pattern mirrors what happens in freestyle when a swimmer skips breaths or breathes on random strokes. Every competitive stroke uses coordinated breathing for a reason. Backstroke is no different. The fact that your face is above water gives you access to air at any time, but access and control are two different things.
Can you breathe anytime during backstroke?
Technically yes, because your face is above water. But breathing at random intervals disrupts CO2 and oxygen exchange, triggers hyperventilation, and destabilizes your body position. A consistent pattern tied to your arm strokes produces better results.
Why do I get out of breath swimming backstroke?
Most likely you’re holding your breath without realizing it or breathing at irregular intervals. Both cause CO2 buildup, which triggers rapid, shallow breathing. A steady exhale through your nose during each stroke cycle solves this.
How to Breathe During Backstroke (Step by Step)
The Inhale-Exhale Pattern Synced to Your Arms
The pattern is simple. As one arm recovers over the water, you inhale through your mouth. As the other arm recovers, you exhale through your nose and mouth. It doesn’t matter which arm you assign to inhale or exhale. Pick one and stay consistent.
The timing detail that matters most: wait until the recovering hand has passed your face before you start the inhale. This accounts for surface tension. For a brief moment after your arm exits the water, water molecules cling to your arm and then drop off. If you inhale during that window, you pull water into your mouth or nose. Waiting until the hand clears your face eliminates this problem entirely. This is a coaching cue that comes directly from Eastern European swim training, where backstroke technique is drilled with this level of precision from the start.
The pattern adapts naturally to different speeds. During a 200m backstroke, your inhales and exhales are longer and more relaxed. During a 50m sprint, they shorten, but the sequence stays the same. Your body adjusts the volume of each breath to match your tempo without you needing to think about it.
When do you inhale and exhale during backstroke?
Inhale as one arm recovers over the water and exhale as the other arm recovers. Wait until the recovering hand passes your face before starting the inhale to avoid swallowing water from surface tension.
The Breathing Pocket – Your Built-In Splash Guard
When you rotate your body during the stroke, the shoulder and armpit on your recovery side rise above the waterline. This creates a physical barrier between your face and the splash zone. Think of it as a wall that shields your mouth and nose from surface water during your inhale.
If water keeps hitting your face while you swim backstroke, you’re probably not rotating enough. A stronger body roll widens the breathing pocket and gives you a cleaner window to breathe. This connection between backstroke body rotation and breathing is one of the most overlooked aspects of the stroke.
How to Tell If Your Backstroke Breathing Needs Work
These are the patterns our coaches at Rocket Swim Club see most often with beginner and intermediate swimmers. Match your symptoms to the cause and fix below.
| Problem | Likely Cause | Fix |
| Gasping after 50m | Holding your breath without realizing it | Exhale steadily through your nose during the entire stroke cycle |
| Water going up your nose | Inhaling too early during arm recovery, before the hand clears your face | Wait until the recovering hand passes your face before inhaling |
| Feeling dizzy or lightheaded | Overbreathing or hyperventilating | Tie your breathing to one specific arm and maintain the pattern consistently |
| Hips sinking | Over-inflating your lungs, shifting buoyancy toward your chest | Control breath volume and avoid gulping maximum air on each inhale |
Most of these problems share a root cause: no consistent breathing pattern. Once you tie your inhale and exhale to specific arms and commit to the rhythm, the secondary issues tend to correct themselves.
Why do I get water in my nose during backstroke?
You’re likely inhaling too early during arm recovery, before the hand clears your face. Water clings to the arm briefly after it exits the pool due to surface tension, then drops off near your face. Waiting solves this.
Why do my hips sink in backstroke?
Over-inflating your lungs shifts your center of buoyancy toward your chest, which pushes your hips and legs down. Control your breath volume on each inhale and avoid gulping maximum air to keep your body balanced.
Drills to Build a Consistent Backstroke Breathing Rhythm
Single-Arm Backstroke Breathing Drill
Swim backstroke using only one arm while the other stays at your side. Focus all your attention on timing the inhale to the recovery phase and the exhale to the pull phase. This drill isolates breathing-arm coordination without the complexity of full stroke. You’ll notice immediately whether your timing is off because you’ll either run out of air or swallow water. Recommended: 4 x 25m per arm.
Tempo Breathing Drill (Slow to Fast)
Start with very slow backstroke, breathing in on one arm recovery and out on the other. After each 50m, increase your stroke rate slightly while keeping the same breathing pattern. At faster tempos, your inhales and exhales shorten but the rhythm stays locked. This drill teaches you how competitive backstrokers adjust breathing for 50m sprints versus 200m races. The tempo drill is a staple of Eastern European swim training methodology, and one of the first drills our coaches use at Rocket Swim Club for backstroke development. Recommended: 4 x 50m building speed.
Cup-on-Forehead Stability Drill
Place a plastic cup half-filled with water on your forehead. Swim backstroke while keeping the cup stable. If the cup falls, you’re moving your head too much. Head movement disrupts the waterline around your face and makes it harder to breathe cleanly. This drill forces a still head position, which directly supports better breathing mechanics. Recommended: 4 x 25m.
How can I practice breathing in backstroke?
Three effective drills: single-arm backstroke to isolate breathing-arm coordination, tempo breathing drill to practice rhythm at increasing speeds, and the cup-on-forehead drill to stabilize head position during the stroke.
What drills help with backstroke breathing?
The single-arm drill isolates inhale-exhale timing. The tempo drill teaches you to maintain the pattern at different speeds. The cup-on-forehead drill corrects head movement that disrupts your breathing window.

How Breathing Affects Your Body Position in Backstroke
Your lungs are the most buoyant part of your body. How much air you hold in them at any given moment shifts your center of buoyancy. Hold too much air and your chest rises while your hips and legs drop. Exhale too aggressively and you lose upper body buoyancy, which lets your face dip closer to the waterline.
The right breathing pattern keeps your lung volume at a steady average. You never fully inflate and never fully deflate. This consistency means your body sits at the same depth throughout the stroke, which reduces the workload on your flutter kick for backstroke. If your kick has to compensate for a body position that shifts up and down with every breath, you’re spending energy on stabilization instead of propulsion.
Does breathing affect body position in backstroke?
Yes. Your lungs are the most buoyant part of your body. Holding too much air raises your chest and sinks your hips. Steady, controlled breathing keeps lung volume consistent and maintains a balanced body position throughout the stroke.
Conclusion
Backstroke breathing is simpler than most swimmers make it. Sync your inhale and exhale to your arm recoveries, let your body rotation create a breathing pocket, and keep your breath volume steady. The drills above give you a structured way to build the rhythm until it becomes automatic. Once your breathing is locked in, you can shift your focus to refining your backstroke kick technique and backstroke body rotation for a faster, more connected stroke.
