The kick is one of the first swimming skills children learn and one of the most consistently misunderstood. Parents watching from the pool deck often see furious splashing and assume vigorous kicking equals effective kicking. In reality, many young swimmers expend enormous energy kicking without generating meaningful propulsion — because the mechanics are off. Improving your child’s kick technique is one of the highest-return investments in their overall swimming development. Here is what good kicking looks like and how to help your child get there.
The Flutter Kick: What It Should Look Like
The flutter kick — used in freestyle and backstroke — is a continuous, alternating up-and-down leg movement. In an effective flutter kick:
The movement originates from the hip. Think of the whole leg moving as one unit from the hip joint, not just the lower leg from the knee down.
The knee has a slight bend, but it is not exaggerated. A minimal, controlled bend allows the foot to accelerate through the down-kick, but excessive bending creates drag.
The ankles are relaxed and flexible. The foot acts almost like a flipper — the more flexible the ankle, the more surface area the foot can push against the water. Children with naturally flexible ankles have a kickable advantage; children with stiff ankles can improve with targeted stretching and practice.
The feet are pointed (plantar-flexed). The toes should be extended, not flexed upward. Flexed feet push against the water from the front rather than redirecting it backward, which creates drag rather than propulsion.
The kick is narrow. The legs move through a relatively small vertical range — typically about 12 to 18 inches. Wide, bicycle-pedaling kicks produce visible splashing but poor propulsion and significant drag.
Common Kicking Errors in Young Swimmers
Bicycle kick: The most common error. Children bend the knee dramatically and alternate as if pedaling a bicycle. This is instinctive — it is how running works — but it is inefficient in water. The knee bend creates frontal drag and does not translate hip-driven force into forward propulsion.
Knee-only kick: Related to the bicycle kick. Children move only from the knee down, holding the upper leg relatively still. This reduces the power available from the larger hip and thigh muscles and produces minimal propulsion.
Tense ankles: Children who kick with the ankles flexed (toes pulled toward the shin) are pushing water the wrong direction. The cure is ankle flexibility work and conscious focus on pointed toes.
Kicking too wide: Some children kick with a very large range of motion, bringing the feet wide apart on each cycle. This creates splash but not speed — and it uses significantly more energy per yard traveled.
How to Improve the Kick
Kickboard drills are the most direct path to kick improvement. With a kickboard held in front, the swimmer can focus entirely on the kick without managing arms or breathing simultaneously. Instructors watch for hip-driven movement and give real-time feedback. Children who struggle to kick effectively while managing a full stroke often show significant improvement in isolated kick work.
Wall kicking: Holding the pool wall at arm’s length and practicing the flutter kick while floating is useful because it gives children immediate feedback. They can see and feel what their legs are doing, and the instructor can observe and correct directly.
Vertical kicking: Treading water using only the flutter kick — no hands — develops hip-driven leg movement and core engagement in a way that transfers to horizontal swimming. It is also more fun for children who find kickboard drills repetitive.
Ankle flexibility exercises: Outside the pool, calf raises, ankle circles, and the “ballerina toes” stretch (sitting with legs extended, pointing and flexing the feet) improve the ankle range of motion that effective kicking depends on. For children with naturally stiff ankles, this off-pool work can make a meaningful difference over time.
Supporting Improvement at Home
In the bathtub, have your child practice the flutter kick while lying on their belly, focusing on pointed toes and movement from the hip. Even this brief, dry practice builds the correct pattern. At family swim time, give specific, simple cues: “kick from your hip,” “point your toes,” or “make your legs long.”
Avoid correcting everything at once. Pick one element and focus on that for a few sessions before adding another cue. Incremental feedback is far more effective than comprehensive correction. Bear Paddle also provides homework tips by swim level to help your child practice.
