How to do it

Perform three single-arm butterfly cycles with the right arm, three with the left, then three full cycles. Keep the dolphin action regular through the whole sequence and use the same two-kick rhythm on each cycle.

Key cues

  • Keep the same rhythm through all three portions.
  • Keep the non-working arm stable during single-arm cycles.
  • Breathe without lifting the head sharply.
  • Fins can help maintain continuity while learning the drill.

Common mistakes

  • Pausing between the groups of three.
  • Losing the two-kick rhythm on the full-stroke section.
  • Suddenly speeding up on the full-stroke section.
  • Increasing amplitude as fatigue builds.

Practice format

4 × 25 m 3-3-3 with 25 to 30 s rest; if technique stays clean, progress to 4 × 50 m at easy effort.
