How to Improve Swimming Technique: Swim Faster with Less Effort

Swimming is the most technique-dependent endurance sport. A skilled swimmer can cruise past stronger athletes who fight the water instead of working with it.

Good technique means less drag, better propulsion, and sustainable speed. Here's how to improve across all strokes.

Why Technique Matters in Swimming

Water is 800 times denser than air. Every inefficiency creates drag that slows you down exponentially. You can't overpower bad technique—you have to fix it.

Good technique provides:

• Less energy wasted fighting the water
• Faster times at the same effort
• Ability to swim longer without fatigue
• Reduced injury risk
• More enjoyable swimming

Universal Principles

Body Position

Stay horizontal and streamlined. Head position controls this—look down, not forward, and your hips and legs will rise.

Rotation

Most strokes involve body rotation from the core. This generates power and reduces shoulder strain.

Catch and Pull

The "catch" is where your hand/forearm grabs the water. A good catch creates propulsion; a poor catch slips through.

Breathing

Breathe efficiently without disrupting body position. Most swimmers lift their heads too much.

Relaxation

Tension kills efficiency. Stay relaxed, especially during recovery phases.

Freestyle (Front Crawl)

Body Position

• Head neutral, looking at pool bottom
• Water line at hairline/forehead
• Hips and legs at surface
• Slight downhill body angle

Rotation

• Rotate 45-60 degrees to each side
• Rotation comes from hips/core, not shoulders alone
• Arm stroke and rotation are synchronized

The Catch

• Enter hand in front of shoulder, fingertips first
• Extend forward underwater before pulling
• Catch: Press down with fingertips, engaging forearm (high elbow catch)
• Pull: Draw hand toward hip, elbow bent ~90 degrees

The Pull

• Early vertical forearm—elbow stays high while hand catches
• Pull through to hip, accelerating
• Exit hand by hip/thigh

Recovery

• Elbow leads, relaxed arm
• Hand swings forward close to body
• Enter smoothly without splash

Kick

• Small, fast flutter kick from hips
• Ankles relaxed and flexible
• Don't bend knees excessively
• 2-beat or 6-beat depending on distance/preference

Breathing

• Rotate head with body rotation—don't lift
• One goggle stays in water
• Breathe in the "pocket" created by your head's bow wave
• Exhale underwater before turning to breathe

Common Freestyle Errors

• Head too high (legs sink)
• Crossing over centerline on entry
• Dropped elbow during catch (slipping water)
• Flat body (no rotation)
• Holding breath instead of exhaling underwater

Backstroke

Body Position

• Ears in water, eyes up
• Hips high at surface
• Slight body angle (head higher than feet)

Rotation

• Similar rotation to freestyle (45-60 degrees)
• Rotate with each stroke

Arm Stroke

• Pinky enters first, arm straight
• Catch with hand/forearm, pull to hip
• Exit thumb first
• Recovery: Straight arm, rotating palm outward

Kick

• Flutter kick, similar to freestyle
• Knees stay underwater
• Kick from hips

Common Backstroke Errors

• Sitting position (hips too low)
• Head lifting to look at feet
• Over-rotating
• Bending knees too much on kick

Breaststroke

Body Position

• Streamlined between strokes
• Body undulates slightly
• Head comes up to breathe, returns to streamline

Arm Stroke

• Start in streamline, arms extended
• Outsweep: Hands press out wider than shoulders
• Catch: Hands catch water, pull back
• Insweep: Hands come together under chest
• Recovery: Shoot arms forward to streamline

Kick

• Feet flex, turn out (dorsiflexion, eversion)
• Knees bend, heels draw toward butt
• Kick back and around in circular motion
• Finish with legs together, feet pointed

Timing

• Pull → Breathe → Kick → Glide
• Arms and legs never work simultaneously
• Glide in streamline after each stroke

Common Breaststroke Errors

• Wide, sweeping arms that go too far back
• Knees dropping (creating drag)
• Rushing through the glide
• Poor timing between arms and legs

Butterfly

Body Position

• Undulating motion from chest through hips
• Press chest down, hips rise; chest rises, hips drop

Arm Stroke

• Simultaneous arm entry, shoulder-width
• Catch: Press down and out, then pull
• Pull: Keyhole pattern under body
• Recovery: Both arms swing forward over water

Kick

• Dolphin kick from hips, legs together
• Two kicks per arm stroke
• Big kick on arm entry, smaller kick on arm exit

Breathing

• Head rises with body undulation
• Look forward and down, not up
• Return head before arms enter

Common Butterfly Errors

• Flat body (no undulation)
• Knees bending too much
• Arms entering too wide or too narrow
• Breathing too high (lifting head)

Drills for Improvement

Freestyle Drills

Catch-up drill: Complete one full arm stroke before starting the other. Focuses on full extension and timing.

Fingertip drag: During recovery, drag fingertips along water surface. Ensures high elbow recovery.

One-arm freestyle: Swim with one arm, other at side. Focus on rotation and catch with single arm.

6-3-6 drill: 6 kicks on side, 3 strokes, 6 kicks on other side. Builds rotation awareness.

Backstroke Drills

One-arm backstroke: Single arm with other at side. Focus on rotation and catch.

6-kick switch: 6 kicks on side, switch to other side with one stroke. Builds rotation.

Breaststroke Drills

2-kick, 1-pull: Two kicks for every one arm stroke. Emphasizes kick power and timing.

Pull with flutter kick: Arms only with freestyle kick. Isolates arm technique.

Butterfly Drills

One-arm butterfly: Single arm with other extended forward. Simplifies coordination.

3+3 drill: 3 strokes right arm, 3 strokes left arm, 3 full butterfly. Builds to full stroke.

Underwater dolphin kicks: Streamline position, dolphin kick only. Builds kick and undulation.

Training Structure

Typical Workout

• Warm-up: 200-400m easy mixed strokes
• Drill work: 4-8 x 50m focused drills
• Main set: Intervals at various intensities
• Cool-down: 100-200m easy

Weekly Focus

• Technical work every session (drills)
• 1-2 harder intensity sessions per week
• Long, easy swimming for aerobic base
• Stroke variety to build all skills

Video Analysis

Film yourself swimming. Review in slow motion.

Check for:

• Body position (are you horizontal?)
• Catch (is your elbow dropping?)
• Rotation (enough? too much?)
• Kick (at surface? from hips?)
• Breathing (lifting head?)

Compare to elite swimmers at your stroke. Identify differences.

Common Mistakes Across Strokes

Fighting the water: Tension wastes energy. Relax.

Overreaching: Enter hand in front of shoulder, not across body.

Poor breathing: Lifting head disrupts body position. Rotate or undulate instead.

Straight arm pull: Bent elbow catches more water than straight arm.

Neglecting kick: Kick provides balance and some propulsion. Don't ignore it.

Rushing: Slow down to feel the water. Speed comes from efficiency, not flailing.

Summary

To improve swimming technique:

1. Focus on body position first - Horizontal, streamlined
2. Master the catch - High elbow, press water back
3. Use rotation - Power from core, not just arms
4. Breathe efficiently - Don't disrupt your position
5. Do drills regularly - Every session
6. Get video feedback - You can't see yourself
7. Be patient - Technique changes take weeks

Swimming is a skill. Treat it like learning an instrument—technique before speed, quality before quantity.

Swim smarter, swim faster.
