Mastering the Freestyle: 5 Drills for a Smoother, Faster Stroke

Beyond the Lap Count: Why Drills Are the True Path to Speed

For years, I believed that the only way to get faster was to simply swim more. I'd log thousands of meters, pushing through fatigue, convinced that grit alone would carve seconds off my time. The results were inconsistent, and I often plateaued or developed shoulder niggles. It wasn't until I started coaching and working with a master's swim club that I had a revelation: the fastest swimmers in the pool weren't necessarily the ones swimming the most yards; they were the ones who swam with the most intention. They dedicated significant portions of their workout to slow, deliberate, and often frustratingly simple drills. This is the people-first truth about swimming improvement: raw volume builds endurance, but intelligent, focused practice builds technique. And superior technique is what converts your energy into forward motion, not splash. This article is born from that experience, distilling years of coaching and personal trial into five foundational drills. We're not just adding tools to your toolbox; we're rebuilding the foundation of your stroke from the waterline up.

The Efficiency Equation: Less Drag, More Propulsion

Every swimming stroke is a constant negotiation between two forces: propulsion and drag. Most recreational swimmers inadvertently increase drag with every kick and pull. For instance, a dropped elbow during the catch phase acts like a brake, while a sinking hip creates a wave of resistance your body must overcome. The drills we'll explore are designed to reprogram these inefficient habits. They isolate components of the stroke so you can feel, understand, and correct them in a low-pressure environment. Think of it like a golfer practicing their swing in slow motion or a pianist playing scales. The goal is to create new, more efficient neural pathways so that when you return to full-stroke swimming, your body defaults to the better technique automatically.

Mindful Practice Over Mindless Laps

The critical shift is from training to practicing. A training mindset focuses on completion—"I need to do 10x100s." A practice mindset focuses on quality—"During these 10x100s, I will focus solely on maintaining a high elbow catch." The drills provided here are your practice curriculum. They require patience and self-awareness. I often tell my swimmers that if a drill feels easy, you're probably not doing it correctly. The discomfort you feel is your body learning a new, more demanding—but ultimately more rewarding—pattern of movement.

Drill #1: The Body Line Foundation - Side Kick with Fins

Before you think about pulling water, you must master the art of slipping through it. The single biggest drain on a swimmer's energy is poor body position. The Side Kick drill is the gold standard for teaching alignment, balance, and the core-driven rotation that is the engine of a great freestyle. I've seen this one drill transform more swimmers' strokes than any other, from anxious beginners to seasoned veterans who never learned proper alignment.

Execution: Finding Your Hydrodynamic Profile

Start by putting on a pair of training fins (they provide stability and allow you to focus on posture). Push off the wall on your side, with your bottom arm extended ahead and your top arm resting on your thigh. Your head should be in a neutral position, looking slightly forward and down, with the waterline cutting between your goggles and hairline. Your body should form a long, straight line from fingertips to toes. Begin a gentle, steady flutter kick from the hips. The goal is not speed, but stillness and length. Breathe by simply rolling your head to the side, keeping your ear on your shoulder, then returning to neutral. Switch sides every 25 meters.

The Key Sensation and Common Faults

The sensation you're seeking is one of effortless glide. You should feel your core engaged, your hips and shoulders stacked, and your entire body riding high in the water. A common fault is letting the bottom shoulder sink, which causes the entire body to twist and drag. Another is lifting the head to breathe, which immediately drops the hips. If you feel unstable, slow your kick and consciously press your extended armpit slightly downward into the water—this often engages the latissimus muscle and stabilizes the torso. This drill isn't just for warm-up; it's a constant diagnostic tool for your body position.

Drill #2: Unlocking Your Core Engine - 6-Kick Switch

Freestyle power doesn't come from your arms alone; it's generated by the coordinated rotation of your hips and shoulders. The 6-Kick Switch drill directly links your kick to your rotation and teaches you to initiate the turn from your core. I prescribe this drill constantly to triathletes and open water swimmers who tend to swim "flat," as it builds the rotational rhythm essential for breathing efficiently in choppy conditions.

Execution: Connecting Kick to Rotation

Begin in the same side-kick position as Drill #1. After six deliberate kicks (count them: one, two, three...), initiate a change to your other side. The movement must be a single, integrated switch, not a series of separate actions. Here’s the sequence: 1) Initiate the turn from your core and hips. 2) Allow your shoulders to follow. 3) As your body rolls, your extended arm performs a spear entry into the water, recovering under the surface. 4) Your other arm begins the pull. You finish in a perfect side-kick position on the opposite side. The head remains neutral, turning with the body.

Why This Transfers to Speed

This drill ingrains the kinetic chain of freestyle: core rotation drives shoulder rotation, which facilitates the arm recovery and sets up a powerful catch. By pausing for six kicks, you force yourself to find balance and patience. The most common error is leading with the head or shoulders, which creates a snaking motion. The power must come from the hips. When done correctly, you'll feel a distinct "zip" as your body slices from one side to the other. This is the feeling of stored rotational energy being released—the same energy that, in full stroke, will add significant power to your pull without extra arm effort.

Drill #3: The Power Source - Catch-Up Freestyle with a Fist

If the body is the hull of the boat, the catch is the propeller. A poor catch—often characterized by a dropped elbow and a slipping hand—is the most prevalent technical flaw I correct. Catch-Up Freestyle slows down the stroke cycle, while making a fist removes your primary sensory tool (your open hand), forcing your forearm to become the primary paddle. This drill is brutally honest; it reveals any weakness in your early vertical forearm (EVF) position.

Execution: Forging a Powerful Early Vertical Forearm

Swim normal freestyle, but with one strict rule: your recovering hand must touch your extended leading hand before you begin the next pull. This creates a long, front-end glide and eliminates any tendency to rush the stroke. Now, make a gentle fist with both hands. Immediately, you'll feel weaker. To move forward, you must consciously engage your entire forearm as a paddle. Focus on initiating the pull by bending the elbow high and pressing the water back with your forearm, not by pulling down with the fist. Keep the recovery relaxed.

The Neurological Rewiring

The magic happens when you switch back to open hands. After 100 meters of fist swimming, your brain has been screaming for more surface area. When you open your hands, your forearms will instinctively maintain that engaged, high-elbow position you worked so hard to create with the fist. The sensation is one of suddenly having massive paddles attached to your arms. You'll feel the water pressure on your forearm and palm from the very start of the pull. This is the foundation of a propulsive catch. I recommend alternating 25m fist/25m open hands to constantly reinforce this connection.

Drill #4: Syncing the Machine - Single-Arm Freestyle

A smooth stroke is a well-timed stroke. Many swimmers have decent individual components but struggle to link them into a fluid whole. Single-Arm Freestyle isolates one arm at a time, allowing you to deeply focus on the coordination between rotation, breath, pull, and recovery. This is my go-to drill for swimmers who look choppy or "fight" the water, as it promotes rhythm and flow.

Execution: Isolating for Integration

Swim freestyle using only one arm. The non-working arm can be held at your side or extended in front (the extended position is more challenging and better for balance). Breathe exclusively to the side of the working arm. This means if you're pulling with your right arm, you breathe to the right. Focus on a full body rotation with each stroke. As your right arm enters the water, your left hip should be rotated up, and vice versa. The kick should be a steady, supportive 2-beat or 6-beat rhythm. Complete a full length with one arm, then switch.

Mastering Timing and Breathing Integration

This drill exposes timing errors with glaring clarity. Do you breathe after the pull, causing a pause? With single-arm, you must time your breath so your face is clear as the arm recovers. It teaches you to breathe as part of the rotational cycle, not as a separate, head-lifting event. Furthermore, by forcing you to breathe to one side, it highlights and corrects bilateral imbalances. A swimmer might discover their left-side breath is smooth, but their right-side breath causes their stroke to collapse. This awareness is invaluable for race planning and open water sighting.

Drill #5: The Final Polish - Zipper Switch / Shark Fin Drill

A high, efficient recovery minimizes drag and conserves energy for the pull phase. A low, swinging recovery or a straight-arm windmill is wasteful and can stress the shoulder. The Zipper Switch drill, sometimes called the Shark Fin drill, exaggerates a proper high-elbow recovery and ties it directly to the body's rotation. I use this as a "polishing" drill for advanced swimmers and a corrective drill for anyone with a sloppy or wide recovery.

Execution: Exaggerating the High-Elbow Recovery

Swim very slowly. As your hand exits the water behind your hip, drag your thumb up the side of your torso—like you're closing a zipper. Keep your elbow high and pointed to the sky. When your thumb reaches your armpit, pause. Your hand will be in a "shark fin" position. From here, consciously roll your body onto its side (this is crucial—the roll enables the recovery, the arm doesn't do the work alone). As you roll, extend your hand forward, leading with the fingertips, and spear it into the water in front of your shoulder. Then execute the pull with the opposite arm.

Promoting Relaxation and Shoulder Health

This drill has a dual purpose. First, it ingrains a compact, energy-efficient recovery path that reduces frontal drag. Second, and just as importantly, it teaches relaxation. The pause at the shark fin position forces you to float and glide, breaking the habit of a frantic, continuous stroke cycle. The slow, controlled movement also strengthens the muscles responsible for shoulder stability in a safe range of motion. For masters swimmers concerned with shoulder impingement, this drill is often a key part of their preventative maintenance routine.

Constructing Your Practice: How to Integrate These Drills

Throwing these five drills into a random workout will yield minimal results. Their power is unlocked through structured, progressive integration. Based on my experience designing seasonal plans for swim squads, the most effective approach is cyclical and focused.

The Focused Practice Session Template

Don't try to master all five in one day. Dedicate 2-3 weeks to a single drill as your Primary Focus. For example, a "Body Position Phase" might start every session with 400m of Side Kick and 6-Kick Switch. Then, swim your main set, but with a single, simple cue derived from the drill, like "long body line" or "rotate from the hips." Your brain can only focus on one or two new things at a time. In the next phase, shift your primary focus to the Catch-Up Fist drill, while using the Side Kick as a brief 200m reminder warm-up. This layered approach builds technique cumulatively.

From Drill Pace to Race Pace: The Transition

The final step is the most often neglected: bridging the gap between slow drill speed and fast swimming. After your drill set, include a transition set. For instance: 4x50m as 25m Perfect 6-Kick Switch / 25m Build Freestyle (increasing speed while holding the technique). Or, 8x25m where you do the first length as Single-Arm, and the second length as Full Stroke, trying to replicate the same rotation and timing. This teaches your nervous system to apply the refined technique under increasing levels of speed and pressure.

The Mental Component: Cultivating Feel for the Water

Technical drills are physical, but their ultimate goal is neurological. They are designed to develop your kinesthetic awareness or "feel for the water." This is the elusive skill that separates good swimmers from great ones. It's the ability to sense pressure on your limbs and torso and make micro-adjustments to maximize propulsion.

Focus on Sensation, Not Just Completion

While executing these drills, turn your attention inward. Ask yourself questions: Where do I feel the water pressure on my forearm during the catch? Is my body gliding or dragging? Is my rotation smooth or jerky? In my coaching, I often have swimmers close their eyes for a length of side kicking to heighten this internal focus. This mindful practice accelerates learning far more than mindlessly counting laps. It transforms swimming from a purely athletic endeavor into a somatic practice.

Patience and the Plateau

Technique change is non-linear. You will have days where a drill finally "clicks," and days where you feel you've regressed. This is normal. The body and brain are reorganizing complex motor patterns. Trust the process. The plateau is not a wall; it's a necessary consolidation phase before the next leap forward. Documenting your feelings in a brief training log can provide motivation, as you'll see your own descriptive language evolve from "clunky" to "connected" over time.

Advanced Applications and Troubleshooting

Once these drills become second nature, they evolve from learning tools into diagnostic tools. They can be adapted to address specific weaknesses or prepare for specific events, demonstrating the deep, flexible expertise behind this method.

Using Drills for Open Water and Triathlon Prep

For open water, the 6-Kick Switch and Single-Arm drills are invaluable. They build the strong, rhythmic rotation needed to sight effectively without disrupting your stroke. Practice Single-Arm freestyle while turning your head to look forward every 4th stroke to simulate sighting. The Side Kick drill also teaches you to maintain composure and balance in a non-sterile environment, a critical open water skill.

Common Problems and Solutions

Problem: "I sink during Side Kick." Solution: Ensure your head is truly neutral (have a coach check). Press your extended armpit down gently. Use fins initially for support.
Problem: "My hips don't rotate in 6-Kick Switch." Solution: Think of leading the switch with your belly button. Make sure your bottom arm is extended directly ahead, not across your centerline.
Problem: "Fist drill makes me so slow I can't maintain form." Solution: Use fins for this drill to maintain a glide speed that allows you to focus on technique, not just survival.

Your Journey to a Masterful Stroke

Mastering the freestyle is a lifelong pursuit, but the journey begins with a single, intentional stroke. These five drills—Side Kick, 6-Kick Switch, Catch-Up Fist, Single-Arm, and Zipper Switch—provide a complete framework for that journey. They address the core pillars of elite swimming: alignment, rotation, propulsion, timing, and recovery. Remember, the goal is not to perform these drills perfectly in isolation, but to harvest the sensations and skills they teach and weave them into the fabric of your full stroke.

I encourage you to approach your next pool session not as a workout, but as a workshop. Dedicate 40% of your time to deliberate drill practice. Be patient, be curious, and focus on the feel of the water. Speed is not something you chase directly; it is the byproduct of efficiency. By investing in your technique through these proven drills, you are building a faster, smoother, and more sustainable freestyle—one that will carry you with grace and power for thousands of meters to come. Now, grab your goggles, and let's get to work.
