Breaststroke & Butterfly Technique Guide
Master the two simultaneous strokes with proper timing, powerful kick, and efficient pull mechanics.
The Simultaneous Strokes
Breaststroke and butterfly are the only strokes requiring simultaneous movement of both arms and both legs. This creates unique timing challenges but also powerful propulsion when executed correctly.
Key similarity: Both strokes use undulating body motion and precise timing between pull and kick.
Key difference: Breaststroke emphasizes glide and efficiency; butterfly emphasizes power and speed.
BREASTSTROKE TECHNIQUE
Why Breaststroke Matters
Breaststroke is the slowest competitive stroke but the most technically demanding. Small errors dramatically impact speed. Proper technique allows for powerful kicks, efficient pulls, and maximum glide.
Body Position
The breaststroke wave:
- Glide phase: Body horizontal, streamlined, head between arms
- Pull phase: Chest rises, hips stay high
- Kick phase: Hips rise, head and chest lower into streamline
Critical principle: High hips throughout stroke. Low hips create massive drag.
Breaststroke Pull
Pull Pattern
- Outsweep: Hands press out and down to shoulder width, catch water
- Insweep: Hands sweep in and up toward chest, elbows stay high
- Recovery: Hands shoot forward together under water back to streamline
Key points:
- Hands never go past shoulder line (pulls beyond shoulders are illegal)
- Elbows stay in front of shoulders throughout pull
- Recovery is quick and streamlined, minimal drag
Common Pull Errors
- Wide pull: Hands going too wide creates drag, wastes energy
- Deep pull: Pulling too deep disrupts body position
- Slow recovery: Lazy forward recovery adds drag time
Breaststroke Kick
The kick provides 60-70% of breaststroke propulsion - most powerful of all strokes.
Kick Mechanics
- Recovery: Heels draw up toward buttocks, knees stay close together
- Catch: Feet dorsiflex (toes toward shins), feet turn outward
- Power phase: Feet push water back in circular motion
- Squeeze: Legs snap together, finishing in streamline
Ankle flexibility: Critical for powerful kick. Inflexible ankles reduce propulsion by 30-40%.
Kick Variations
- Whip kick: Narrow knee position, powerful snap. Fastest but requires flexibility.
- Wedge kick: Wider knee position, easier for beginners.
Common Kick Errors
- Scissor kick: Asymmetric kick (illegal in competition)
- Wide knees: Knees wider than hips creates drag
- Dolphin kick: Vertical kicking motion (illegal except on start/turn)
- Weak dorsiflex: Toes pointed instead of flexed reduces power
Breaststroke Timing
The famous breaststroke rhyme: "Pull, Breathe, Kick, Glide"
Timing Sequence
- Streamline glide: Arms extended, legs together, body horizontal
- Pull starts: Hands press out, body stays streamlined
- Breathe: Head rises as hands insweep, quick breath
- Recovery: Hands shoot forward, head returns down
- Kick: Feet drive back as hands reach full extension
- Glide: Body fully streamlined, momentum carries forward
Critical timing point: Kick finishes as hands reach full extension. This is when maximum glide occurs.
Breaststroke Breathing
- One breath per stroke cycle (required by rules)
- Head rises naturally with body undulation
- Quick breath during insweep phase
- Head returns underwater as hands extend forward
Common error: Lifting head too early or keeping it up too long disrupts body position.
Breaststroke Pullouts
One underwater pullout allowed after start and each turn:
- Streamline: Glide in tight streamline off wall
- Pull: Big pull down to hips (like butterfly underwater)
- Recovery: Hands recover under body back to streamline
- Dolphin kick: One dolphin kick allowed during pull or recovery
- Breaststroke kick: First breaststroke kick brings head to surface
Common Breaststroke Mistakes
1. Gliding Too Long
Problem: Excessive glide slows stroke rate too much.
Fix: Glide only until you stop accelerating (about 1 second).
2. Kicking During Pull
Problem: Kick and pull overlap, wastes propulsion.
Fix: Pull first, then kick as hands extend forward.
3. Low Hips
Problem: Hips sinking creates massive drag.
Fix: Stronger kick, press chest down during glide, engage core.
4. Head Too High
Problem: Looking forward instead of down sinks hips.
Fix: Look down during glide, lift only to breathe.
Breaststroke Drills
- 2 Kicks, 1 Pull: Two breaststroke kicks per arm pull. Emphasizes kick power.
- Pull with Pull Buoy: Isolates arm technique, focuses on pull mechanics.
- Kick on Back: Breaststroke kick while on back. Checks leg symmetry.
- 3-3-3 Drill: 3 strokes underwater, 3 normal, 3 fast. Timing practice.
BUTTERFLY TECHNIQUE
Why Butterfly Matters
Butterfly is the most powerful and athletic stroke, requiring full-body coordination. When done correctly, it's faster than breaststroke and can rival backstroke speed. Poor technique leads to exhaustion and shoulder injury.
Body Position: The Dolphin Wave
Butterfly uses continuous body undulation like a dolphin:
- Head position: Neutral, looking down and slightly forward
- Body wave: Starts at head, travels through chest, hips, to feet
- Hip height: Hips rise and fall with wave, breaking surface at highest point
The wave timing: Body undulates twice per arm cycle (two kicks per pull).
Butterfly Arm Stroke
Entry and Catch
- Entry: Hands enter shoulder-width apart, thumbs down
- Extension: Arms extend forward and slightly out
- Catch: Hands pitch outward, elbows stay high, forearms vertical
Pull Phase
Butterfly uses hourglass pull pattern:
- Outsweep: Hands press out to wider than shoulders
- Insweep: Hands sweep in under chest toward centerline
- Upsweep: Hands press back and up, finishing at thighs
Power point: Maximum acceleration during insweep when hands are under chest.
Recovery
- Over water: Arms swing forward together over water surface
- Relaxed: Recovery should feel loose, letting momentum carry arms forward
- Low and fast: Elbows slightly bent, arms swing low over water
Butterfly Kick
The dolphin kick provides 30-40% of butterfly propulsion.
Kick Mechanics
- Full body motion: Kick starts from chest, travels through hips and legs
- Legs together: Feet stay together, like mermaid tail
- Whip action: Downward whip of feet, slight knee bend
- Both kicks matter: Downkick provides power, upkick maintains rhythm
Two Kicks Per Stroke
- First kick (small): During hand entry and catch
- Second kick (large): During insweep and upsweep, provides main propulsion
Butterfly Timing
The sequence:
- Hands enter, first small kick
- Hands catch and pull
- Second large kick as hands pass under chest
- Hands push to thighs, body rises
- Arms recover over water, body undulates forward
Critical timing: Large kick happens as hands push past chest. This creates powerful forward surge.
Butterfly Breathing
- Breathe forward: Head lifts straight forward (not to side) during insweep
- Chin on surface: Minimum lift, chin barely clears water
- Breathe every 1-3 strokes: Most swimmers breathe every 2 strokes in races
Advanced technique: One-arm butterfly breathing (alternating arms) for training.
Common Butterfly Mistakes
1. Lifting Head Too High
Problem: Excessive head lift sinks hips, disrupts rhythm.
Fix: Breathe forward with minimal lift, let body undulation bring head up.
2. Straight-Leg Kick
Problem: No knee bend makes kick weak and tiring.
Fix: Allow slight knee bend, focus on hip drive and whip action.
3. Late Second Kick
Problem: Kicking after hands finish push loses momentum.
Fix: Time large kick as hands pass under chest.
4. Arm-Only Pull
Problem: Using only arms without body undulation.
Fix: Emphasize body wave, let wave power the stroke.
Butterfly Drills
- One-Arm Butterfly: One arm pulls while other stays extended. Alternates each stroke.
- 3-3-3 Butterfly: 3 strokes right arm, 3 left arm, 3 full stroke.
- Underwater Butterfly: Full butterfly stroke underwater. Focuses on timing.
- Vertical Butterfly Kick: Dolphin kick while vertical in deep water. Builds kick power.
