Introduction
Ask any triathlete about their biggest challenge, and swimming often tops the list. The front crawl improvement drills—the primary stroke in triathlon—can feel like a constant battle against technique flaws, breathing difficulties, and that frustrating feeling of sinking legs. Whether you’re preparing for your first sprint triathlon or aiming to qualify for Kona, mastering proper front crawl technique isn’t just about going faster—it’s about conserving precious energy for the bike and run ahead. In this comprehensive guide, we’ll break down the essential components of efficient front crawl form and provide actionable front crawl drills that will transform your swim technique, boost your confidence, and ultimately improve your triathlon performance.
Why Perfect Front Crawl Form Matters for Triathletes
Unlike pool swimmers who specialize in swimming alone, triathletes face unique challenges that make proper front crawl improvement drills technique even more crucial:
- Energy Conservation: With two more disciplines awaiting, efficient swimming means you’ll exit the water fresher for the bike and run.
- Open Water Adaptability: Good front crawl technique translates better to open water conditions, helping you navigate chop, currents, and sighting without losing form.
- Injury Prevention: Proper technique reduces strain on shoulders, neck, and back—common problem areas for triathletes with form flaws.
- Wetsuit Optimization: With correct front crawl form, you’ll better harness the buoyancy and hydrodynamic benefits of your wetsuit.
- Reduced Anxiety: Technical proficiency breeds confidence, particularly important in chaotic mass swim starts.
A small improvement in front crawl efficiency can yield significant time gains across longer distances while requiring less physical effort—the holy grail for any triathlete.
Understanding the Fundamentals of Proper Front Crawl Technique
Body Position
The foundation of effective front crawl begins with horizontal body position. Think of your body as an arrow cutting through the water, with head, shoulders, hips, and feet aligned at the surface. The key to this position is core engagement—your abdominals should be lightly engaged throughout the stroke to maintain hip position.
Many triathletes struggle with sinking legs, which creates drag and slows you down significantly. This often stems from lifting the head too high or failing to engage the core. To counter this, focus on pressing your chest slightly deeper into the water while maintaining a neutral head position. This natural counterbalance helps elevate your legs toward the surface.
Body Rotation
Rotation around your longitudinal axis (imagine a skewer running from head to toe) is essential for powerful, injury-free swimming. Proper rotation:
- Engages larger back muscles instead of relying solely on shoulders
- Creates a longer effective reach
- Facilitates easier breathing
- Reduces strain on the shoulder joint
Aim for approximately 45-60 degrees of rotation from center to each side, driven from your core rather than forced by your arms. Your shoulders and hips should rotate as a unit, maintaining alignment throughout the stroke cycle.
Arm Stroke
The arm stroke consists of four key phases:
- Entry and Extension: Your hand enters the water fingertips first, about shoulder-width from your head’s midline. Extend forward just below the surface, reaching from the shoulder rather than slapping the water.
- Catch: The most technical phase where you position your arm and hand to “grab” the water. Maintain a high elbow position (elbow higher than wrist, wrist higher than fingertips) to create an effective pulling surface.
- Pull-Through: Pull back along your body’s centerline, accelerating your hand through the stroke. The pull pattern resembles an “S” shape when viewed from below.
- Recovery: After exiting the water near your hip, relax the arm and bring it forward with elbow leading. Keep this phase relaxed with minimal muscle tension.
Common mistakes include dropping the elbow during the catch (reducing power), crossing over the midline on entry (causing snaking), and incomplete follow-through (shorting your stroke potential).
Leg Kick
Unlike pool specialists, triathletes typically employ a lighter, more economical kick that primarily serves to:
- Stabilize body position
- Aid in rotation
- Maintain rhythm
A 2-beat or 4-beat kick (referring to the number of kicks per complete arm cycle) is usually sufficient for triathlon swimming. Focus on kicking from the hip with relatively straight legs, keeping feet relaxed and ankles flexible. Your kick should create minimal splash, with feet just breaking the surface.
Breathing Technique
Many front crawl struggles stem from breathing difficulties. The key principles for effective breathing include:
- Exhale underwater: The most common mistake is holding your breath. Exhale steadily through your nose/mouth while your face is in the water.
- Rotate to breathe: Breathing should be integrated with your natural body rotation, not an independent head movement.
- Low to the water: Keep one goggle in the water when turning to breathe, creating a small pocket of air rather than lifting your entire head.
- Bilateral breathing: Practice breathing to both sides (every 3 strokes) for balanced stroke development and adaptability in race conditions.
When timed correctly, breathing becomes part of your rhythm rather than an interruption to it.
Head Position
Maintain a neutral head position with eyes looking directly toward the bottom of the pool at approximately a 45-degree angle forward. Your head leads your spine’s alignment—lift it too high, and your hips and legs will sink. Many triathletes instinctively look forward, which creates unnecessary strain on the neck and disrupts body position. Practice keeping the back of your head partially out of the water, with water line crossing somewhere between hairline and crown.
Effective Front Crawl Drills to Improve Your Technique
Drills for Body Position & Rotation

- Start with 20-30 seconds and gradually increase duration.
Benefits: Dramatically strengthens core muscles essential for maintaining horizontal body position, improves kick efficiency, and builds specific swimming endurance.
Drills for Arm Stroke Technique
Fingertip Drag Drill
What it is: A recovery technique drill emphasizing proper arm position and relaxation.
How to perform it:
- Swim normal front crawl, but during the recovery phase (arm coming forward).
- Lightly drag your fingertips across the water surface.
- Focus on leading with the elbow and maintaining a relaxed forearm.
- Continue normal swimming otherwise, including regular breathing.
Benefits: Promotes proper high-elbow recovery, prevents crossover at entry, teaches relaxation during recovery, and reinforces good entry hand position.
Catch-Up Drill
What it is: A timing drill where one arm waits for the other to complete its cycle.
How to perform it:
- Begin with both arms extended forward in streamline position.
- Pull with one arm through a complete stroke cycle.
- Return this arm to the extended forward position.
- Only when both arms are together in front should you begin the next arm’s stroke.
- Continue alternating arms with this “catch-up” pause between strokes.
Benefits: Emphasizes full extension, improves stroke timing, allows focus on each arm’s technique individually, and reinforces proper body rotation with each stroke.
Single Arm Freestyle Drill
What it is: A drill isolating one arm’s stroke while the other remains inactive.
How to perform it:
- Extend one arm forward while keeping the other arm at your side.
- Swim using only the extended arm for propulsion.
- Focus on complete arm cycles and proper breathing technique.
- After 25-50 meters, switch to the other arm.
- Advanced version: Hold a kickboard with the inactive arm.
Benefits: Isolates each arm’s mechanics, highlights imbalances between arms, improves rotational timing, and forces proper body rotation to breathe.
Drills for Leg Kick Technique
Kickboard with Arms at Sides
What it is: A variation of kickboard work that removes the stability of extended arms.
How to perform it:
- Hold a kickboard against your chest with both hands.
- Alternatively, you can hold it extended in front but with arms at your sides.
- Focus on kicking from your hips, not knees.
- Keep a straight body line and relaxed ankles.
- Practice both face down (holding breath or with snorkel) and on your back.
Benefits: Develops kick power and rhythm, builds kick-specific endurance, and emphasizes body position maintenance without arm support.
Kick with Fins
What it is: Using swim fins to enhance kick technique and ankle flexibility.
How to perform it:
- Attach swim fins to your feet (shorter training fins preferred over diving fins).
- Perform normal kicking drills or swimming with added propulsion.
- Focus on maintaining a narrow kick from the hips with pointed toes.
- Concentrate on upward and downward movements rather than bending knees excessively.
Benefits: Improves ankle flexibility, builds specific kick muscles, provides feedback on proper kick mechanics, and creates a feel for good body position.
Drills for Breathing Technique
Exhalation Bubbles Drill
What it is: A focused breathing exercise emphasizing underwater exhalation.
How to perform it:
- Swim regular front crawl but exaggerate your exhalation, creating visible bubbles.
- Focus on continuous exhalation through both nose and mouth when face is underwater.
- Start exhaling immediately after inhaling.
- Inhale quickly when turning to breathe, then resume exhaling.
- Try counting your exhalation (1, 2, 3) to ensure it’s continuous.
Benefits: Establishes proper breathing rhythm, prevents breath-holding, reduces breathing-related anxiety, and improves overall stroke rhythm.
3-3-3 Drill
What it is: A breathing pattern drill that develops bilateral breathing and stroke balance.
How to perform it:
- Swim 3 strokes breathing to your left side.
- Then swim 3 strokes breathing to your right side.
- Finally, swim 3 strokes with bilateral breathing (breathing every 3rd stroke, alternating sides).
- Repeat this 3-3-3 pattern continuously.
Benefits: Develops balanced breathing to both sides, improves neck flexibility for breathing, teaches breathing rhythm variations critical for open water, and identifies/corrects side preferences.
Side Kick Drill with Breathing
What it is: A drill focusing exclusively on the breathing position and movement.
How to perform it:
- Extend your right arm forward, with left arm at your side.
- Rotate onto your right side (90 degrees from face-down).
- Kick steadily while maintaining this position.
- Practice breathing by rotating your head to inhale, then returning face to water.
- After 25-50 meters, switch to the other side.
Benefits: Isolates the breathing motion, develops comfort breathing while rotating, strengthens the neck muscles used in breathing, and improves body rotation awareness.
Drills for Coordination & Timing
Broken Swim Drill
What it is: Breaking full swimming into manageable segments with brief pauses.
How to perform it:
- Swim 3-5 strokes with perfect technique.
- Pause briefly in a comfortable position (extended front glide or on your back).
- Reset mentally, focusing on the next technical element you want to improve.
- Continue with another 3-5 perfect strokes.
- Gradually increase the number of strokes between pauses.
Benefits: Prevents technique breakdown from fatigue, allows mental resets to focus on form, builds stroke awareness, and develops the feel for proper technique.
Build Sets
What it is: Progressively increasing swim speed while maintaining technique.
How to perform it:
- Divide your swim distance into segments (typically 25m or 50m).
- Start the first segment at very easy, technique-focused pace (60% effort).
- Gradually increase intensity with each segment (70%, 80%, 90%).
- Focus on maintaining proper technique as speed increases.
- Reset and repeat for several rounds.
Benefits: Teaches pace awareness, develops ability to maintain technique at higher speeds, identifies when form breaks down, and builds specific swimming fitness.

Common Front Crawl Mistakes to Avoid
Even experienced triathletes can develop technique flaws that limit their swimming potential. Watch for these common mistakes:
- Crossing Over the Midline: Hands entering the water directly in front of your head rather than at shoulder width, causing snaking and inefficient propulsion. Quick fix: Imagine swimming over a lane line, with each hand staying on its respective side.
- Dropped Elbow During Pull: Allowing your elbow to drop early in the pull phase reduces power and increases shoulder strain. Quick fix: Think of your forearm and hand as a paddle, maintaining a high elbow position throughout the pull.
- Lifted Head Position: Looking forward instead of down increases drag and causes legs to sink. Quick fix: Focus your gaze on the bottom of the pool, keeping one goggle in the water when turning to breathe.
- Over-kicking: Using excessive leg movement depletes energy without proportional speed gains. Quick fix: Develop a lighter, more rhythmic kick from the hips, not the knees.
- Holding Breath: Failing to exhale continuously underwater creates tension and disrupts rhythm. Quick fix: Practice audible, steady exhalation whenever your face is in the water.
- Incomplete Rotation: Swimming too flat reduces reach and power while increasing shoulder strain. Quick fix: Imagine rotating your shoulder to the sky when taking each stroke.
- Wide Kick: Splaying legs outward creates drag and wastes energy. Quick fix: Imagine kicking through a small tube, keeping movements compact and driven from the hip.
