Kicking Technique for Kids: Why We Teach the Frog Kick First

Kicking Technique for Kids: Why We Teach the Frog Kick First By the Oyougu Aquatics Coaching Team If you are searching for kicking technique for kids in a swimming context, the short answer is this: a young child learns to kick best when the movement suits their body. For most 3-year-olds, that means a relaxed frog kick (the leg action of breaststroke) first, and the freestyle flutter kick afterwards, once their balance, hips and confidence are ready. When parents watch our early-years classes, one question comes up again and again: “Aren’t kids supposed to learn freestyle kicking first? Why are you teaching my 3-year-old a frog kick?” In competitive swimming, the flutter kick is usually introduced first. But teaching independent water safety to a 3-year-old is very different from training a 7-year-old for stroke efficiency. This guide explains our reasoning, what good kicking looks like at each age, and how you can support your child between lessons. OyouguAquatics Build Safer Kicking Skills Oyougu Aquatics teaches children through a structured SwimSafer 2.0 curriculum, with personalized attention from certified instructors. Explore swimming lessons Key takeaways At age three, we work with a child’s natural movement. A gentle frog kick usually gives a toddler safer, more controlled movement than a flutter kick they cannot yet coordinate. A good flutter kick starts at the hip, with loose ankles and a streamlined body. It develops gradually and is taught after floating and balance. Progress varies from child to child. Even in Singapore’s national programme, fewer pupils met Stage 3 requirements than Stage 1 , so there is no need to rush. Confidence comes before technique. A comfortable child learns faster and stays safer than one pushed to swim strokes early.

Working with toddler reflexes, not against them When a 3-year-old tries to flutter kick, we very often see a “bicycle kick”. They pump their knees high towards their chest, pull their toes up and churn the water without moving forward much. It is tiring, it is noisy, and it can leave the child frustrated. That bent-knee pattern has more in common with a frog kick than with a straight-legged, hip-driven flutter kick. So instead of correcting a movement the body keeps repeating, we shape it: knees bend, feet turn out, legs push back and together. The child is working with their reflex, and they feel the water carry them. 2. The flutter kick asks for a lot at once An efficient flutter kick needs several things to happen together: The movement starts at the hip, not the knee. The legs stay fairly long and straight. The ankles are loose and floppy, like flippers. The body stays flat and streamlined, so legs are not fighting drag. These are the key technique points described in ActiveSG’s swimming guidance , and they are very reasonable goals for an older child. For a 3-year-old, hips, core and coordination are all still developing, so we do not expect them to hold all four together. Research on children at different levels of a learn-to-swim programme shows why patience matters. A kinematic study of the prone flutter kick looked at how skilled swimmers produce a smooth wave of movement from the hip, and how beginners differ. Beginners tend to treat the kick as separate, disjointed movements, often bending mainly at the knee. Connecting hip to lower leg is a skill that builds with time. 3. A frog kick gives early, usable independence Our aim with a toddler is not a race-ready stroke. It is personal water safety: the ability to move, change direction, and get back to the wall or a parent. A slow, relaxed frog kick, with the child’s face and body calm, gets them moving with less effort. A high-effort, low-efficiency flutter kick cannot yet do that. This fits the heart of the national programme. SwimSafer is built to develop confidence and independence in the water, covering forward and backward movement, safe entry and exit, and personal water safety. 4. Confidence matters more than technique Global drowning data explains why safety comes first. The World Health Organization’s Global report on drowning prevention treats drowning as a major cause of child death, and structured instruction as part of the response. A child who feels comfortable in the water, in an encouraging setting, is better placed than one pushed through strokes before they are secure with buoyancy. Where the flutter kick comes in We do not skip the flutter kick. We place it where it works. Swim England’s learn-to-swim guidance describes skills as introduced, developed and mastered. That matches how we teach kicking: Stage of learning What we focus on What you may see Introduced Water comfort, floating, body position, a simple leg action (often a frog kick at age 3) Short glides, lots of encouragement, small wins Developed Kicking from the hip, alternating legs, streamlined arms Flutter kick with a board or on the back, still a bit bent at the knee Mastered Consistent kick, coordinated with arms and breathing Smooth freestyle and backstroke kick over longer distances The order is not fixed by age alone. Some 4-year-olds are ready for a light alternating kick on their back. Some 6-year-olds still need to work on their balance first. Our coaches watch each child and decide. Balance comes before power Parents often expect kicking drills to be the main thing. Balance matters just as much. A study on balance training in young swimmers found that core and balance work changed the kinematics of the flutter kick. In plain terms, when the body sits steadily in the water, the legs have a stable base to work from. That is why our early lessons spend so much time on floating and gliding before intense kicking. What good kicking looks like, in plain words You do not need to be a swimmer to spot the basics. Here is a checklist you can use from the poolside. For a frog kick Knees bend, but not too far. Heels come towards the bottom, not the chest. Feet turn out. Toes point outwards, like a duck’s feet. A push and a squeeze. Legs push round and back, then close together. A short glide. The child stretches out for a moment before the next kick. For a flutter kick Kick from the hip. The whole leg moves, not just the knee. Soft ankles. Feet are relaxed and pointed, not stiff or flexed. Small, steady kicks. The feet stay close to the surface, with no huge splash. Flat body, head in line. Tummy and hips stay up, not sagging. Common mistakes are bending only at the knee, flexing the feet, kicking too deep and holding the head high. All of these are normal at the start. The scoping review Learning how to swim in 5- to 12-year-old children shows that coaches use a range of motor learning methods with this age group, and there is no single magic cue. We use short, simple instructions, because children respond better to “kick like a frog” than to a list of joint angles. How you can help between lessons You do not need a pool for most of this. A few minutes of play can reinforce what happens in class. Bath-time kicks. Let your child sit and splash with their feet. Ask for “sleepy kicks” and “big kicks”. Floor frog legs. Lying on their tummy, show them how to bend knees, turn feet out and push back. Wall holds. In the pool, with you close by, let them hold the wall and practise gentle kicks. Praise effort. Say “I saw you try that” more often than “do it like this”. Keep sessions short and cheerful. If your child is tired or nervous, stop and try again another day. Pressure tends to make kicking stiffer, not stronger. When your child grows into longer swims and wants to understand effort levels, a general guide to heart rate zones for swimming can help older swimmers and parents understand pacing. This is for later, not for toddlers. How kicking fits into SwimSafer 2.0 In Singapore, most children follow the SwimSafer 2.0 programme, which has six progressive stages. It is also used in primary schools. The MOE notes that swimming is a key learning area in the Physical Education syllabus , and that SwimSafer is how schools give students basic swimming and water survival skills. The programme expects stroke technique to grow with the stages. By the Silver level, the instructors’ block plan emphasises stroke technique development and coordinated breathing in deep water. Good kicking habits formed early make that stage easier. If you want to see what each stage involves, these guides from our team are a good place to start: What kids learn in SwimSafer Stage 1 Why a 90% quiz score isn’t enough for Stage 2 The 50m swim and quiz timing for Stage 3 An overview of all six SwimSafer 2.0 stages Choosing a coach who teaches kicking properly A good kick depends on a coach who can see small details and explain them simply. In Singapore, coaches teaching at ActiveSG pools should be registered with the National Registry of Coaches (NROC) and hold a valid SwimSafer 2.0 instructor certification, along with first aid and AED training, according to ActiveSG’s SwimSafer information . Ask to see this before you sign up. Our guide on 5 checks to verify an NROC swim coach walks you through it. Class size matters just as much. A coach with a large group cannot watch each child’s knees and ankles. That is why we cap every class at six students. Our perspective: one foundational skill at a time We believe a child’s first kick should feel easy. When a 3-year-old pushes back with a frog kick and glides forward, you can see them realise that the water will hold them. That moment of confidence is the most valuable thing we can give in an early lesson. We do not see the frog kick as a detour from freestyle. We see it as the foundation of safe independence at that age. The flutter kick follows when the child is balanced, strong enough and curious about it, and by then it tends to arrive more smoothly. Our classes and curriculum are developed in-house, and we do not outsource our lessons. Our coaches are full-time and NROC and SwimSafer certified, so the person who notices your child’s kick is the same person who plans the next step. — Oyougu Aquatics See how we teach kicking in a trial lesson The easiest way to see whether our approach suits your child is to try it. We offer a trial lesson at S$32.50 one-off. Our group classes are S$130 per month, with no registration fees or deposits, and a maximum of six students per class. You can read more about our fees and class options , or look at our toddler swimming lessons and children’s swimming lessons . We teach at ActiveSG pools including Bishan Swimming Complex and Teck Ghee Swimming Complex , as well as Delta and Jalan Besar. Frequently asked questions At what age should a child learn the flutter kick? There is no single age. Many children begin to manage an alternating kick between ages four and six, once they can float and hold a streamlined position. Our coaches decide based on balance and comfort, not the birthday. Is the frog kick bad for learning freestyle later? No. For a 3-year-old, it builds comfort, forward movement and leg strength. When the child moves on to freestyle, the coach introduces the hip-led flutter kick as a new skill, and the earlier confidence helps. Why is my child’s kick all knees? This is very common among beginners. Young children bend at the knee because the hips and core are still developing. Floating practice, balance games and gentle reminders to “kick from your tummy” help over time. Does my child need a kickboard? Not at first. Early lessons often use a coach’s support, the pool wall or floats so that your child can focus on body position. A board becomes useful later, when your child can keep a flat position and wants to practise longer kicks.
