Hand and Leg Coordination in Swimming: Timing and Drills

How Do You Improve Hand and Leg Coordination in Swimming?

Most adults can learn a decent kick and a decent arm stroke on their own. The trouble starts when the two have to work together: the legs stop when the arms pull, or the kick fights the stroke instead of helping it. This guide shows you how to build hand and leg coordination one stroke at a time, with the timing to aim for and the drills that teach it.

Practise the kick and the arms separately first, then join them slowly with one timing cue per stroke. In freestyle and backstroke, keep a steady kick going under the arms. In breaststroke, pull first and kick second, then glide. In butterfly, kick once as the hands go in and once as they push back. Drills such as catch-up and single-arm swimming make the timing easier to learn.

Learn Each Part on Its Own First

Coordination is easier to build from parts you can already do. Spend part of each session on the legs alone, holding a kickboard or kicking on your side with one arm stretched forward. Our guide on how to improve your swim kick covers the kick itself, from kicking from the hips to keeping the ankles loose.

Then practise the arms with the legs quiet. Standing in the shallow end and walking the arm stroke through the water is enough at first. Once both parts feel easy on their own, join them at a slow speed. If you want to understand why this matters before you start, our article on why coordination is important in swimming explains what goes wrong when the timing is off.

Freestyle: Keep the Kick Going Under the Arms

In freestyle, the arms take turns while the legs keep up a small, steady flutter kick. The most common fault is not the kick itself but the kick stopping. Many adults kick well until they pull or turn to breathe, and then the legs go still and sink. Your first goal is a kick that never stops, however slowly it runs.

Use one cue: kick through the breath. As your head turns to breathe, think about your feet and keep them moving. Many recreational swimmers settle into a rhythm of six kicks for each full arm cycle, and others use two. Either works. What matters is that the kick is continuous and that your body rolls with each arm, rather than lying flat.

Freestyle Drills for Hand and Leg Coordination

The catch-up drill is the classic place to start. Keep one arm stretched forward and only begin the next pull when the other hand touches it. The pause gives you time to check that the legs are still kicking. Side kicking, with six kicks on one side before you take one stroke and roll to the other side, joins the roll to the kick.

Single-arm freestyle, with the other arm resting at your side, teaches you to time the breath with one arm while the kick stays steady. Our guide to learning how to swim freestyle covers the full stroke once the timing feels natural.

Breaststroke: Pull, Breathe, Kick, Glide

Breaststroke is the one stroke where the arms and legs should not work at the same moment. The order is pull, breathe, kick, glide. The arms sweep out and in, and you lift your head to breathe. Then, as the hands shoot forward, the legs kick, and you hold a long, straight glide before the next pull.

The fault to look out for is pulling and kicking together. The two movements then cancel each other out, and you feel as if you are working hard and going nowhere. The cue that fixes it is “arms first, legs second”. If your hands are still pulling when your feet begin to kick, you have started the kick too early.

Breaststroke Drills for Hand and Leg Coordination

Try two kicks to one pull. Take one full pull and breath, then do two kicks with your arms held straight in front of you. It slows the stroke down and makes you feel the kick happen while the arms are still. Then go back to one kick for each pull, keeping the same order.

Separation drills help too. Pull, stop for a count of one with your arms forward, kick, and glide for a count of two. Shorten the pauses over a few lengths until the stroke flows. Our guide to learning how to swim breaststroke takes you through the kick and the arm sweep in detail.

Backstroke: A Steady Kick Under a Turning Arm Cycle

Backstroke uses the same continuous flutter kick as freestyle, with the arms turning over in a steady windmill. Because you are on your back, a weak kick shows up quickly: the hips drop and you start to sit in the water. Keep the kick small and steady, with your toes just breaking the surface.

The arms should be opposite each other, so that one hand enters the water as the other finishes its push. Your shoulders roll a little with each arm. If the kick stops each time an arm recovers, slow the arms down until the kick can keep its rhythm.

Backstroke Drills for Hand and Leg Coordination

Kick on your back with both arms by your sides until you can hold your hips up for a full length. Then try single-arm backstroke, swimming with one arm while the other rests by your side, and change arms each length.

The six-kick switch joins the two. Kick on your side with one arm up and one arm down, take one stroke to roll to the other side, and kick again. Our guide to learning how to swim backstroke covers the arm entry and body position.

Butterfly: Two Kicks for Each Arm Cycle

In butterfly, both arms move together and the legs make a dolphin kick, with the whole body moving in a gentle wave. The timing is two kicks for each arm cycle. The first kick comes as your hands enter the water in front of you. The second, often smaller, comes as your hands push back past your hips, and it helps lift the arms out for the recovery.

Most adults lose the second kick, and then the arms have to drag themselves out of the water. The cue is “kick the hands in, kick the hands out”. Say it in your head on every stroke until the rhythm becomes your own. U.S. Masters Swimming’s guide to butterfly timing describes the same rhythm of two kicks for each pull, and warns against missing the kick as the hands come out.

Butterfly Drills for Hand and Leg Coordination

Start with body dolphin: arms stretched forward, no arm stroke, moving the wave from your chest down to your feet. Then try single-arm butterfly, with one arm forward and the other doing the stroke, keeping both kicks in each cycle. Swap arms each length, and only join both arms once the two kicks come easily. Our guide to learning how to swim butterfly explains the arm pull and the breath.

Putting Hand and Leg Coordination Into a Session

A short, regular routine teaches timing faster than long, tiring sets. Warm up with easy swimming, then spend a block of the session on one stroke: a length of kick only, a length of arms only, then a length of a drill, then a length of the full stroke at a slow pace. Pick one cue for the session and think only about that.

At a busy public pool after work, such as an ActiveSG swimming complex, choose a quieter lane for your drill lengths. Drills are slower than normal swimming, and a calmer lane gives you room to stop and reset your timing.

Stop the drill when you feel the timing slip from tiredness, because practising a broken rhythm teaches the wrong habit. A swimmer who swims slowly with the right timing improves faster than one who swims hard with the wrong timing.

When a Coach Helps

Timing is hard to see in yourself. A coach can watch from the deck and tell you in one sentence that your kick stops when you breathe, or that your breaststroke kick starts too early. That kind of feedback can save weeks of practising the wrong rhythm. A private swimming lesson lets your coach choose the drills for the stroke you find hardest to coordinate.
