Two-beat butterfly timing

How to do it

Swim controlled butterfly while mentally counting two kicks per cycle. The first accompanies hand entry and extension; the second accompanies the end of the pull and helps the arms recover. Slow down instead of adding extra kicks when timing breaks down.

Key cues

• Place the first kick around hand entry.
• Place the second kick around the end of the pull.
• Keep the kicks compact and continuous.
• Let body rhythm connect the two actions.

Common mistakes

• Putting both kicks almost at the same moment.
• Missing the second kick as the hands finish the pull.
• Using large knee-driven kicks.
• Chasing speed before the rhythm is stable.

Practice format

6 × 25 m easy butterfly with 25 to 30 s rest, counting “one-two” on each cycle.
