The breaststroke kick is nothing like freestyle or butterfly kick. It requires hip external rotation, a whip-like leg motion, and precise timing with the pull. Most adult swimmers do it wrong — here’s how to fix it.
The Mechanics
A correct breaststroke kick (whip kick) works like this:
- Recovery: Draw your heels toward your glutes, knees dropping slightly below hip level. Feet come up, not out.
- Sweep: Feet rotate outward (flex the ankles outward) and sweep back in a circular arc.
- Finish: Feet snap together in a streamline position.
The most common errors:
- Knees splaying too wide (sit-down kick) — creates drag on recovery
- Not pointing toes enough on the finish — reduces propulsion
- Timing the kick before the pull is complete — disrupts the stroke’s glide phase
Drill 1: Kick on Your Back
What it fixes: Hip and knee position during the kick cycle.
How: Lie on your back in the water, arms at your sides. Perform the breaststroke kick while looking at the ceiling. You can see your knees — they should stay below the water surface during recovery, not breaking up out of the water.
Sets: 4×25m on back, :20 rest. If your knees break the surface, your recovery is too wide.
Drill 2: Streamline Kick (No Arms)
What it fixes: Kick power and finish position.
How: Push off the wall in streamline (arms overhead), kick breaststroke with no arm movement. Focus on feeling the propulsion from each kick and the glide phase between kicks.
Sets: 4×25m streamline kick, :20 rest. Count your kicks per 25m.
Drill 3: 2-Kick 1-Pull
What it fixes: Timing between kick and pull.
How: Perform two breaststroke kicks, then one pull-and-breathe cycle. This slows down the timing and makes you conscious of the sequencing.
Sets: 4×50m 2-kick/1-pull, :20 rest. Then 2×50m regular breaststroke applying the same timing awareness.
Hip Flexibility
If your breaststroke kick feels stiff or you can’t get much propulsion, hip external rotation may be limited.
Stretches that help: butterfly stretch (sitting, soles of feet together), pigeon pose, seated hip external rotation. 5–10 minutes daily for 4 weeks shows meaningful improvement in kick range.
Timing With the Pull
The single most important timing point: kick as your arms finish recovering to full extension forward. The glide should happen when your body is fully extended — arms forward, legs together, flat in the water.
If you kick while your arms are still mid-recovery, you lose the streamline and the glide. The kick and the pull-recovery should finish simultaneously.
