How to swim butterfly: a step-by-step guide

Butterfly looks brutal but it is mostly timing. The kick, the pull and the breath, broken into pieces you can actually learn.

Butterfly has a reputation as the hardest, most exhausting stroke. The truth is that most of the exhaustion comes from fighting the timing rather than a lack of strength. Get the rhythm right and butterfly becomes smooth, almost bouncy. Here is how to build it piece by piece.

Start with the kick

Butterfly is driven by two dolphin kicks per stroke cycle. The kick comes from the core and hips, not the knees. Practise it on your front with arms extended, feeling the wave move from your chest down through your legs.

Add the pull

The arms move together. Reach forward, catch the water, and press back towards your hips in a keyhole shape, then recover over the surface with relaxed arms.

  • First kick as your hands enter the water out front.
  • Second kick as your hands press past your hips.
  • That second kick is what lifts you to breathe.

Breathe low and late

Push your chin forward just above the surface to breathe, not up high. Lifting your head too far drops your hips and stalls the stroke. Breathe every two strokes to start, dropping to every stroke only once the rhythm is solid.

The quick version

  • Two kicks per arm cycle, driven from the core.
  • Kick in as hands enter, kick out as hands exit.
  • Breathe low and forward, not high.

Swim it in short bursts at first, 4 x 25m with full rest, focusing on rhythm not distance. Butterfly rewards timing over effort every time.
