Swim drill

Single-Arm Freestyle

Swim freestyle with one arm only, the other arm extended forward and quiet. Breathe to the working-arm side. Switch arms at the wall. Isolates each side so flaws can't hide behind the other arm.

The one cue

Press, don't slap

The lesson

  1. 1

    One arm works, one waits

    Swim freestyle with one arm while the other stays extended forward and quiet at the surface.

  2. 2

    Press, don't slap

    Enter the hand cleanly and press water backwards rather than slapping down onto it.

  3. 3

    Enter on your own side

    Don't cross the centreline — the imaginary line running down the middle of your body.

  4. 4

    The test

    Breathe to the working side and switch arms at the wall. Nothing can hide behind the other arm here, so notice which side feels worse.

Watch out for

  • Lead arm sinking — keep it extended at the surface
  • Breathing to the wrong side — should breathe to the working side
  • Crossing the centerline on entry
