Nobody sets out to learn a bad habit. But in one 45-minute session at a neighbourhood pool, a beginner can repeat the same flawed stroke three hundred times — and muscle memory does not care whether the movement was right or wrong. That is why plenty of Singaporeans who have swum for years still finish two laps gasping, while someone who started six months ago glides past them.
The encouraging part is that almost every beginner problem traces back to a short list of fixable errors. Below are the ten that turn up most often in local pools, and what to do about each. Working through this list will do more for your swimming than another month of grinding out laps.
Why beginner swimming mistakes are so hard to shake
Water punishes hesitation. When a new swimmer feels unstable, the body does what it has always done on land: it lifts the head, tenses the neck, and reaches for something solid. None of that helps in a pool, but it feels safer, so the brain files it away as a survival move.
The second reason is invisibility. You cannot see your own stroke, so most of the errors below are things people repeat for years without ever knowing.
Mistakes in body position and breathing
1. Lifting the head to breathe instead of rotating it
This is the most common fault in freestyle. Lifting the head forward pushes the hips and legs down, turning a streamlined body into a plough. The swimmer kicks harder to compensate, burns through their oxygen, and concludes they are simply unfit.
- The fix: keep one goggle lens in the water when you breathe. Think of your head as skewered on a rod running from crown to spine — it rotates with the shoulder, it does not lift.
- Drill: six kicks on your side with the lower arm extended, breathing to the ceiling, then six on the other side.
2. Holding your breath underwater
Beginners often inhale, hold everything in, then try to exhale and inhale in the split second their mouth clears the water. It never works. Carbon dioxide builds up and the swimmer stops at the wall convinced they need more stamina.
Exhale continuously through your nose and mouth the entire time your face is submerged. When you turn to breathe, your lungs should already be empty and ready to fill. This one change transforms more beginners than any arm technique ever will, and it is usually the first thing a good instructor works on in adult swimming lessons.
3. Swimming with the hips too low
Low hips create drag that no amount of effort overcomes. Besides head position, the usual culprits are a stiff lower back and looking straight ahead like a periscope. Aim your gaze down and slightly forward, press your chest lightly into the water, and let the hips float up behind you.
Mistakes with the arms and legs
4. Kicking from the knees
The bicycle kick — knees bending, feet churning — creates enormous drag and almost no propulsion. Kicks should start at the hips, with loose ankles and a relatively straight (not locked) leg. Kick small, kick fast, and keep your feet inside the shadow of your body.
Stiff ankles are common among adults who run or cycle. A minute a day of gently pointing the toes on the pool deck helps more than people expect.
5. Crossing the centre line on hand entry
When the hand enters the water past the midline of the body, the swimmer snakes from side to side and wastes energy correcting course. Enter the water in line with your shoulder, extend forward, and only then begin the catch.
6. Pulling with a dropped elbow
A dropped elbow means the forearm slips through the water instead of anchoring against it. Think of reaching over a barrel: the fingertips angle down, the elbow stays high near the surface, and the whole forearm becomes the paddle. This is the hardest item on this list to self-diagnose, which is exactly why a session or two with a qualified swimming coach pays for itself quickly.
Mistakes that happen outside the water
7. Practising too little, too far apart
One long swim a fortnight builds almost nothing. Two or three shorter sessions a week beat a single marathon effort, because skill retention depends on frequency, not duration. The Health Promotion Board’s activity guidance points the same way — regular moderate sessions across the week rather than one heroic burst.
Frequency is one reason so many families now book lessons at their own condo pool. When the pool is downstairs, a 30-minute practice is realistic on a weeknight; when it is a bus ride away, it quietly stops happening. If you do not have pool access at home, a nearby public swimming complex works just as well, and searching for swimming lessons near me is usually cheaper than a gym membership you skip.
8. Treating water safety as somebody else’s job
Swimming a length is not the same as being safe. Sport Singapore’s national learn-to-swim framework and the water safety education promoted by the Singapore Lifesaving Society both emphasise survival competencies — floating, treading, calling for help, self-rescue in clothing — not just strokes. Adults skip these because they feel remedial. They are the part that matters if something goes wrong at a beach or reservoir.
- Never swim alone, however competent you feel.
- Teach children to enter feet first in unfamiliar water.
- Practise floating on your back until you can hold it calmly for a minute.
- Respect open water — currents, cold, and fatigue behave nothing like a pool.
9. Fighting your own gear
Goggles that leak or fog will wreck a session. Press them onto dry eye sockets without the strap: they should hold briefly by suction. If not, the shape is wrong for your face and tightening will not save them. A kickboard is useful for isolating the legs but becomes a crutch if every lap involves one.
10. Learning entirely from videos
Online drills help once you know what you are working on. The problem is that beginners cannot tell which of these faults they actually have, so they fix the wrong one while the real issue continues. One honest assessment — even a phone video shot from the side of the pool — is worth a dozen tutorials.
A simple four-week self-correction plan
- Week 1 — Breathing. Start every session with two minutes of bobbing: exhale fully underwater, inhale at the surface. Then swim easy laps thinking only about exhaling.
- Week 2 — Head and hips. Add side-kicking drills and one goggle lens in the water on every breath. Film one lap from the side.
- Week 3 — Kick and entry. Small, fast kicks from the hips; hands entering in line with the shoulders. Count strokes per length and try to reduce the number, not the time.
- Week 4 — Put it together. Short repeats of 25 to 50 metres with generous rest. Stop the set the moment technique falls apart.
Four weeks of this beats four months of aimless laps. If progress stalls at the same point twice, that is the signal to get eyes on your stroke.
When it is worth bringing in a coach
Self-correction has a ceiling. Most swimmers hit it once the obvious faults are gone and the remaining issues are subtle — timing, catch, rotation.
This is the practical case for guided instruction. SwimmingClasses.sg runs private swimming lessons and small-group sessions across Singapore with certified coaches and flexible scheduling, covering children’s classes, toddler water familiarisation, ladies-only lessons, adult beginners, condo pools, and special needs swimming programmes. Families who want a second opinion on their child’s progress can simply get in touch and describe what is going wrong.
Frequently asked questions
How long does it take an adult beginner to swim properly?
Most adults training twice a week can swim a continuous 25 metres of recognisable freestyle within eight to twelve weeks. Comfort in deep water often arrives before good technique does, and that gap is normal.
Which mistake should I fix first?
Breathing. Exhaling underwater is the foundation everything else sits on, and correcting it usually improves head position and hip position at the same time without any extra work.
Is it too late to fix bad habits after years of swimming?
No. Unlearning takes longer than learning, but adults rewire strokes all the time. Expect a temporary dip in speed while the new pattern settles — that dip means it is working.
Are group or private lessons better for correcting technique?
Private lessons correct faster because the coach watches only you. Groups are better value and add motivation. A common approach is a few private sessions to fix specific faults, then group swimming to build fitness. Options for both are widely available through Singapore swimming lesson providers.
How often should children practise between lessons?
Even one short, playful session a week between lessons makes a visible difference, particularly for young children whose progress depends on water comfort rather than strength. Free play counts.
Do I need to be fit before starting lessons?
No. Swimming builds its own fitness, and poor technique makes almost everyone feel unfit in the water. Start with technique and let conditioning follow.
What if my child has additional needs?
Look for instructors experienced in adaptive teaching, smaller classes, and a willingness to move at the child’s pace. Specialist special needs swimming programmes are built around exactly this.
The takeaway
Better swimming rarely comes from trying harder. It comes from removing the habits quietly working against you — the lifted head, the held breath, the knee-driven kick — then giving the corrected pattern enough repetitions to stick. Pick one fault, work it for a fortnight, move to the next.
If you would rather not guess which fault is yours, a single assessment session with an experienced instructor will tell you in ten minutes what a year of solo laps will not. Around Singapore you will also find learn-to-swim programmes at Swim2u, condo pool coaching, teacher training through a recognised swimming instructor course, and internationally benchmarked curricula from Swim Schools International. Beyond the pool, our sister network also covers home tuition, aircon servicing and digital marketing services for Singapore families and businesses.
