One of the hottest debates in the swimming and triathlon world is whether you should breathe bilaterally when you swim (i.e. regularly swapping breathing sides). If you have a look around the internet you'll soon find some swim coaches arguing that you are best off not bothering and just breathe to one side instead. This is a tempting argument to subscribe to if you find bilateral breathing hard - as many swimmers do!
At Swim Smooth we think quite differently. Breathing regularly to both sides is such a powerful way to develop and maintain good stroke technique, and offers such a strategic advantage in races, that it would be mad to ignore it.
In fact, your breathing pattern is so important to your swimming that a huge number of common stroke flaws have a strong tendency to develop when you only breathe to one side. These include crossovers, scissor kicks, timing problems, poor catch technique and shoulder injury!
So let's take a look at the most common reasons given for not bothering with bilateral breathing:
Reason 1. Elite swimmers never bilaterally breathe - so neither should you.
Actually elite swimmers do frequently breathe bilaterally, especially during training to develop a symmetrical stroke. The great Ian Thorpe used bilateral breathing to great effect to win 'The Race Of The Century' - the 200m freestyle at the Athens Olympics. Thorpie swapped sides every lap to breathe towards his main rival Peter van den Hoogenband to always keep him in his sights.
Other swimming legends have been quoted as blaming the fact that they didn't breathe bilaterally as the reason they didn't win an event, e.g. Grant Hackett in the final of the men’s 400m freestyle at the 2007 World Championships - Hackett breathed away from the competition in the final 50m and dropped from 1st to 3rd because he couldn't see what was happening in the race.
Reason 2. You will run out of oxygen, especially during a race.
Only if you're doing it wrong! Usually the reason people run low on oxygen is because they're not exhaling well enough underneath the water - improve this aspect of your swimming and you'll unlock the ability to breathe bilaterally. Plus when you have a side chop or swell in open water (or like Thorpie need to breathe to one side to keep an eye on a competitor) unilateral breathing will feel very easy.
The challenge with breathing in swimming isn't getting the air in - it's actually getting it out! Improve your exhalation technique and getting enough oxygen in becomes easy, even when breathing bilaterally.
Reason 3. If breathing to one side causes you to swim off course in open water, just sight forwards more frequently to compensate.
The problem with this argument is that the more you sight forwards, the more your legs will drop low and create drag, even in a wetsuit. This happens for any swimmer, even for elite open water swimmers and triathletes. Plus, constantly coming off course because your stroke is lopsided and then correcting is hard work all by itself.
Breathing bilaterally in training helps you develop a nice symmetrical stroke technique so you swim inherently straighter, meaning you have to sight less frequently to swim straight and make far fewer corrections. This is something we should all work towards (see this video clip for a great example of why).
Reason 4. Old dogs can’t learn new tricks.
Actually they can - but only if they're willing to try. Many swimmers have it so ingrained in their head that "I can't" quickly becomes "I won't"! If you are thinking "Yeah, yeah, I’ve heard it all before" then be very careful, could breathing to one side be the one thing that’s always held you back with your swimming?
It's far too easy to give up on bilateral breathing before giving it a decent try and discovering the benefits.

How about you decide to break through the "bilateral breathing hump" now? Not tomorrow, not next week, not in the off-season, but now. Here's a truly objective set to try to show you the potential it might offer you too:
Are you faster than you thought to your least favourite side? Could this be the bad habits on your favoured side not existing on your 'bad' side. Could that be worth working on and improving yet further? Yes, it could!
Reason 5. Your neck will become sore if you try breathing to the other side.
When you breathe, your body needs to rotate along the long axis of your spine. You do this quite naturally to your favourite breathing side but probably less so to your least favourite side.
Trying to breathe to your least favourite side without adequate rotation will see you twisting your neck and lifting your head, and yes this will soon make your neck sore. Develop better rotation (and timing) to that least favourite side and this will no longer be an issue.
Reason 6. There’s no way you'll ever be as good breathing to your least favourite side as to your good side, so don't even bother.
We've performed many thousands of stroke correction sessions at Swim Smooth and we can tell you for a fact that most swimmers actually breathe with better technique on their least favourite side. It may feel awkward because you're not used to it but it's very likely your timing is better and you keep your head in a much better position when you breathe because you don't have any bad habits on that side.
Reason 7. You’ll fish-tail down the pool if you try to breath bilaterally.
Actually, exactly the opposite is true. If you develop your body rotation equally to both sides (in the region of 45 to 60º but no more), you will develop a much more symmetrical stroke and be well on your way to eradicating cross-overs and asymmetries which cause fish-tailing.
It is actually unilateral breathers that suffer much more from fish-tailing than bilateral breathers.
Reason 8. You haven’t got time to learn yet another skill.
Learning to breath bilaterally doesn't need to occupy your every waking moment, really it shouldn't take any additional training time to learn. At first you can just include it in your warm-up and cool-down before progressively adding it into other parts of your sessions.
Your ability to breathe equally well to both sides will pay huge dividends in open water as there are many occasions when you need to breathe to one side strategically. This could be breathing away from side waves or chop, or breathing towards a competitor to draft them effectively to their side and match their stroke rate.
The successful open water swimmer and triathlete is one who is adaptable enough to "roll with the punches" (or waves) when required, sometimes literally!
Reason 9. You’ll never get comfortable with it and will always feel under stress when doing it.
First and foremost the secret to breathing bilaterally is all about a smooth, constant exhalation in the water. In some parts of the world swimmers are taught to hold onto their breath to improve buoyancy - but the only place this will add buoyancy is in the chest region and so sink the legs even further.
You'd never hold onto your breath when you cycle or run, so why do it when you swim? Doing so only turns an aerobic activity into a much more anaerobic activity and that's bound to make anyone fatigued and stressed regardless of which side they breathe.
From statistics we've collected on our clinics, if we took a group of swimmers at random over 80% will be holding onto their breath for at least a second under the water. A second might not sound like a lot, but if you are only breathing every 2 strokes that's almost the entire time your face is under the water. Learn to "let it go" and your transition to bilateral breathing will become much easier.
Reason 10. If you already find breathing every 2 hard, imagine how hard breathing every 3 will be!
As well as holding your breath underwater, another classic reason for finding breathing every 3 strokes hard is when swimmers have tried to over-lengthen their strokes and added a pause-and-glide into their timing. This makes your stroke turnover (stroke rate) very slow and increases the time between breaths dramatically.
If you recognise yourself as a bit of an Overglider then working on the rhythm of your stroke will also make bilateral breathing much easier as the time between breaths reduces. And then you'll get all the benefits to your stroke that bilateral breathing brings.
In a nutshell:
- Bilateral breathing helps to improve your symmetry and balance in the water, reducing your drag, swimming straighter and reducing the chances of shoulder injury.
- Bilateral breathing lets you keep your options open when swimming in open water, specifically breathing away from side swell and chop, and drafting close to other swimmers to the side.
- Bilateral breathing gives you a tactical advantage in pool races as you are able to monitor your competitors and respond to any moves they make.
It's so easy to say that bilateral breathing is too hard and give up on it but are you truly doing your swimming any favours with this outlook?

How about you decide to break through the "bilateral breathing hump" now? Not tomorrow, not next week, not in the off-season, but now. Here's a truly objective set to try to show you the potential it might offer you too:
Swim 3 sets of 5x 100m. Take 15 seconds rest between each 100m and 45 seconds rest between each set of 5. Swim the first set only breathing to your left (preferably every 4 strokes), the second set to your right (preferable every 4 strokes) and the third set bilaterally (every 3). Monitor your times through the set.
Are you faster than you thought to your least favourite side? Could this be the bad habits on your favoured side not existing on your 'bad' side. Could that be worth working on and improving yet further? Yes, it could!
Reason 5. Your neck will become sore if you try breathing to the other side.
When you breathe, your body needs to rotate along the long axis of your spine. You do this quite naturally to your favourite breathing side but probably less so to your least favourite side.

| To improve your rotation to your poor breathing side, think about rotating your hip out of the way as your hand comes through. |
