Most swimmers in Singapore aren’t held back by fitness or fear – they’re held back by a handful of technique habits nobody ever corrected. You swim a few laps, get out of breath fast, and assume you just need to “build stamina.” More often than not, the real problem is form. Fixing a couple of small habits can make swimming feel dramatically easier almost overnight.
Below are the seven most common swimming mistakes we see again and again in pools across Singapore, from condo pools to public swimming complexes, along with practical fixes you can try on your very next swim.
Why Small Technique Errors Cause Big Problems
Water is roughly 800 times denser than air, so even a small positioning error creates a lot of extra drag. A swimmer who lifts their head too high, or kicks from the knees instead of the hips, isn’t just swimming “less efficiently” – they’re fighting the water on every single stroke. Over time this leads to fatigue, frustration, and for many adult learners, a loss of confidence that keeps them out of the pool altogether.
The Singapore Lifesaving Society teaches that skills like floating and controlled breathing are foundational survival tools, not just performance add-ons – when you get tired or panicked in the water, good technique is often what keeps you calm and afloat. Sport Singapore and the Health Promotion Board both continue to promote swimming as one of the best low-impact ways to stay active, which makes it worth taking the time to get the basics right rather than muscling through years of bad habits.
1. Lifting the Head Too High to Breathe
Why it happens
This is by far the most common mistake among self-taught swimmers. The instinct to lift your whole head out of the water for a “big gulp” of air feels safer, but it does the opposite of what you want.
How to fix it
When your head lifts, your hips and legs naturally sink, turning your body into a drag anchor. Instead, rotate your head to the side as part of your body roll, keeping one goggle lens in the water. Your mouth only needs to clear the surface enough to grab a breath – think of it as turning your head to rest on a pillow rather than lifting it up.
2. Breathing Only to One Side
Why it happens
Most swimmers develop a dominant breathing side early on and never move past it. It feels comfortable, so there’s little incentive to change.
How to fix it
One-sided breathing creates muscular imbalance and often leads to swimming in a slight curve rather than a straight line. Practise bilateral breathing (every three strokes) during warm-up laps. It will feel awkward at first, but within a few sessions your stroke usually becomes noticeably more balanced and symmetrical.
3. Swimming with a Straight Arm and No Body Rotation
Why it happens
Beginners often think swimming freestyle means “windmilling” straight arms as fast as possible. It looks powerful, but it’s inefficient and tiring.
How to fix it
Bend your elbow on the recovery (the part of the stroke above water) and let your torso rotate along its long axis with each arm pull. This rotation engages your stronger back and core muscles instead of relying purely on your shoulders, which is exactly the kind of adjustment a certified swimming coach will usually spot within the first few minutes of watching you swim.
4. Kicking from the Knees Instead of the Hips
Why it happens
A big, bent-knee “bicycle kick” feels like it should generate more power, so many self-taught swimmers default to it without realising it’s working against them.
How to fix it
An efficient flutter kick starts from the hip, with the knee staying fairly relaxed and only slightly bent. Try kicking with a board while focusing on small, quick movements that start at the hip rather than the knee. Ankle flexibility matters here too – spend a minute pointing and flexing your feet before you start.
5. Holding Your Breath Underwater
Why it happens
It feels natural to hold your breath the way you would jumping into a pool for fun, but in continuous swimming this habit quickly leads to breathlessness and a rising sense of panic.
How to fix it
Exhale steadily and continuously through your nose and mouth while your face is underwater, so your lungs are already empty and ready for a fresh breath the moment you turn your head. This single change is one of the fastest ways to reduce that “out of breath after two laps” feeling that frustrates so many adult learners.
6. Skipping a Proper Warm-Up and Drill Work
Why it happens
Time-pressed swimmers often jump straight into laps, treating drills as optional extras rather than part of the workout.
How to fix it
A short warm-up of easy kicking, arm circles, and a few relaxed lengths wakes up the right muscles and reduces injury risk, especially for shoulders. Drills such as catch-up freestyle or single-arm swimming isolate one part of your stroke at a time, which is often the quickest way to fix a specific habit rather than trying to overhaul everything at once.
7. Trying to Self-Correct Without Feedback
Why it happens
Because you can’t easily see your own stroke from underwater, most self-taught swimmers are working off guesswork – and habits formed this way tend to stick around for years, even after you know they’re wrong.
How to fix it
An outside eye makes an enormous difference. Whether that’s a friend filming you on a phone, browsing technique videos on a resource like Swim2u, or a session with a real coach, external feedback is what turns “I think I fixed it” into “I actually fixed it.”
How Structured Coaching Fixes These Habits Faster
Every one of the seven mistakes above is easy to describe but surprisingly hard to feel and fix on your own, which is exactly where good coaching earns its keep. At swimmingclasses.sg, certified coaches run private, small-group, kids’, adult swimming lessons and toddler swimming lessons across Singapore, with flexible scheduling built around your week rather than a fixed class timetable.
Families often start with kids’ swimming lessons to build good habits from the start, while parents of children with additional needs can look into special needs swimming lessons, which are paced and structured specifically around the child rather than a generic curriculum – a similar philosophy to the specialised guidance offered by specialneeds.com.sg. If a public pool feels intimidating, one-to-one private swimming coaching or lessons at your own condo swimming facility can be a far more comfortable place to iron out these habits before venturing back to a busy swimming complex.
If you’d rather work with someone qualified from day one, it’s worth spending a little time comparing options – search swimming near me or browse Singapore swimming lessons listings, and look for a genuinely certified swimming coach rather than someone teaching purely from personal experience. Coaches who’ve gone through a proper swimming instructor course are trained to spot exactly the kind of small positioning errors described above, often within a single lesson. You can reach the swimmingclasses.sg team directly through their contact page to ask about availability.

Frequently Asked Questions
What is the single most common swimming mistake?
Lifting the head too high to breathe is the most common issue we see, since it causes the hips and legs to sink and creates significant extra drag on every stroke.
How long does it take to fix bad swimming technique?
Simple habits like breathing rhythm can improve within two to three sessions of focused drill work. Deeper habits, like body rotation or kick timing, usually take four to eight sessions of consistent practice with feedback.
Can adults really fix swimming habits they’ve had for years?
Yes. Adult learners often progress faster than expected once a coach identifies the specific habit causing the problem, because adults can consciously apply corrections that young children may not yet understand.
Do I need private lessons, or can I fix these mistakes on my own?
Some issues, like breathing rhythm, can be improved solo with practice. Others, like body rotation or kick position, are hard to feel from the inside and usually improve much faster with outside feedback from a coach or a filmed video.
Is kicking from the knees really that much of a problem?
Yes – a bent-knee, bicycle-style kick creates drag and wastes energy without generating much forward propulsion, which is why swimmers who fix it often report their legs feel less tired after a swim, not more.
Should children learn correct technique from the start?
It’s much easier to teach correct habits early than to unlearn incorrect ones later, which is one reason structured children’s classes tend to focus heavily on fundamentals before speed.
What should I look for in a swimming coach?
Look for relevant certification, a clear teaching plan rather than unstructured “just swim laps” sessions, and a coach who explains why a correction matters, not just what to change.
Final Thoughts
None of these seven mistakes are complicated once you know what to look for, which is exactly why they’re worth fixing sooner rather than later. Start with one habit at a time – breathing rhythm and head position are usually the best place to begin – and give yourself a few sessions of focused practice before moving on to the next. If progress feels slow, a few lessons with a qualified coach can save months of frustrating trial and error, and get you back to enjoying the water instead of fighting it.
