Watch any elite swim squad train and you will notice they spend a surprising amount of time not swimming fast laps but performing slow, deliberate drills. That is no accident. Elite swimmers understand that speed is built on efficient technique, and the fastest way to improve technique is to isolate one element of the stroke, exaggerate or simplify it, and groove a better pattern before folding it back into full swimming. This guide covers the drills the best swimmers and coaches rely on, organized by what they develop, so you can borrow the same tools.

Why Drills Work

A full swimming stroke is a complex, fast-moving sequence, and trying to fix everything at once usually fixes nothing. Drills work by reducing the complexity: they slow the action down, remove or simplify part of it, or force you to feel something you normally ignore. This lets your nervous system build a cleaner motor pattern without the distraction of the whole stroke. The key is intention. A drill done mindlessly is just slow swimming; a drill done with focus on its specific purpose rewires technique. Elite swimmers drill with complete attention on the one thing each drill is meant to improve.

Drills for the Catch and Pull

The catch, how you grip and hold the water at the front of the stroke, is where propulsion begins, and elite swimmers obsess over it.

• Sculling: small, figure-eight movements of the hands and forearms while keeping the body still, teaching you to feel and hold the water. Done at the front of the stroke, mid-pull, and at the hips.

• Fist drill: swim freestyle with your hands closed in fists, which removes the paddle of your palm and forces you to engage your forearm to grip water. When you open your hands again, the catch feels dramatically larger.

• Catch-up: one arm waits extended in front until the other completes its stroke and 'catches up,' emphasizing a long body line, a patient front-quadrant timing, and a full, complete pull.

Drills for Body Position and Rotation

Efficient swimming comes from rotating around a long, balanced body line, not from windmilling the arms. These drills build that:

• Single-arm freestyle: swim using one arm while the other stays extended or rests at your side, forcing you to rotate, balance, and breathe to a less natural side.

• 6-kick switch (6-3-6): kick six times on your side in a streamlined position, take three strokes, then switch to the other side, grooving rotation and a stable, balanced line.

• Fingertip drag: during the recovery, drag your fingertips along the surface of the water, which promotes a high elbow recovery and relaxed arm and reinforces good rotation.

Drills for the Kick

A strong, efficient kick stabilizes the body and adds propulsion, and elite swimmers devote whole sets to it. Vertical kicking, treading in a streamline with no arms in deep water, builds raw kick power and core stability. Kicking on your side, in a streamlined position with the bottom arm extended, trains the rotation and balance you need while swimming. Underwater dolphin kick sets develop the powerful undulation that drives every push-off. Many of these are done with a kickboard for stability or with fins to build power and ankle flexibility.

How Elite Swimmers Use Equipment

Training tools are not crutches when used with purpose; they are precision instruments that let you target a specific skill.

• A front snorkel lets you focus entirely on body position, catch, and rotation without the disruption of turning your head to breathe, which is why so many technique drills are done with one.

• Hand paddles increase the surface area of your hand, exaggerating the feel of the catch and building pulling strength, while also revealing flaws in your catch when your stroke slips.

• Swim fins add propulsion and resistance for kick development, build ankle flexibility, and let you hold a faster, more streamlined body position while you work on technique.

• A pull buoy isolates the upper body by floating your legs, letting you focus on the catch, pull, and rotation without kicking.

The expert approach is to match the tool to the goal: a snorkel and paddles for catch and body position, fins for kick and speed-of-movement, a pull buoy for upper-body isolation. Used deliberately and in moderation, these tools accelerate technique work.

Building Drills Into Your Training

Elite swimmers do not save drills for a special session; they weave them throughout their training. A typical approach includes technique drills in the warm-up when the body is fresh and the mind is sharp, short drill segments between hard swimming sets to reset technique under mild fatigue, and occasional dedicated technique sessions focused entirely on one stroke or one skill. The goal is always to transfer the drill into full swimming, so most drills are followed by a few lengths of normal swimming that consciously apply what the drill taught. Over time, the better pattern becomes automatic, and that is when technique work shows up as speed.

The Mindset That Separates Elite Drilling

The difference between elite swimmers and everyone else is often not which drills they do but how they do them. They drill slowly and precisely, with total attention on the single element each drill targets, and they connect every drill back to the full stroke. They are patient, knowing that grooving a new pattern takes many repetitions over weeks, and they are honest, using tools and feedback to find flaws rather than hide them. Borrow the drills, but borrow the mindset too: slow down, isolate, feel the water, and rebuild. That is how technique, and ultimately speed, is made.

Structuring a Technique Session

Knowing the drills is only half the picture; using them in a sensible structure is what produces results. A productive technique session generally moves from simple to complex and from slow to fast. Begin with an easy warm-up, then introduce drills while you are fresh and your mind is sharp, since technique work demands concentration that fades when you are exhausted. Work on one or two specific elements per session rather than scattering your attention across everything, and follow each drill with a few lengths of normal swimming that consciously apply what the drill taught, so the new pattern transfers into your full stroke. Keep the efforts controlled; the point of drilling is precision, not speed. Over a training week, you might dedicate parts of several sessions to technique and one session more heavily to it, always connecting the drills back to the stroke you are trying to improve.

Match Drills to Your Weaknesses

The most effective drilling is targeted. Rather than running through a generic list, identify your specific weaknesses, perhaps a dropped elbow in the catch, poor rotation, a weak kick, or asymmetrical breathing, and choose the drills that address them. A swimmer who drops the elbow benefits most from sculling and fist drill; one who swims flat benefits from rotation drills like 6-kick switch and single-arm; one with a weak kick needs vertical and side kicking. Honest feedback is essential here, so use a coach's eye or video to find what actually needs work rather than drilling what already feels comfortable. Elite swimmers are ruthlessly honest about their flaws and aim their practice directly at them, which is a large part of why their technique keeps improving. Treat your drill selection as a prescription for your particular stroke, not a one-size-fits-all routine.

Finally, remember that technique work rewards patience and consistency above all. A single focused drill session will not transform your stroke; grooving a better movement pattern takes many repetitions over weeks, with the new pattern gradually becoming automatic. Elite swimmers accept this and return to the fundamentals again and again, refining the same elements over years rather than chasing a quick fix. Treat drills as a permanent part of your training rather than a remedy you reach for only when something feels wrong, keep your attention sharp on the specific purpose of each one, and always connect them back to full swimming. Do that consistently, and the small, deliberate improvements compound into a stroke that is genuinely faster and more efficient, which is the whole point of drilling in the first place.

Frequently Asked Questions

What drills do professional swimmers use?

Professional swimmers rely on drills that isolate one part of the stroke: sculling and fist drill for the catch, catch-up and fingertip drag for stroke timing and recovery, single-arm and 6-kick switch drills for rotation and balance, and vertical and side kicking for propulsion. They pair these with tools like snorkels for body position, paddles for catch awareness, and fins for kick power, always done slowly and with full focus.

How do drills improve swimming technique?

Drills reduce the complexity of the full stroke by slowing it down, simplifying it, or forcing you to feel something you normally ignore, which lets your nervous system build a cleaner movement pattern. The key is intention: a drill done with focus on its specific purpose rewires technique, while a drill done mindlessly is just slow swimming. Most drills are followed by normal swimming to transfer the improvement.

What is the fist drill in swimming?

The fist drill is freestyle swum with your hands closed in fists, which removes the paddle of your palm and forces you to engage your forearm to grip and hold the water. It builds awareness of the catch using the whole arm rather than just the hand. When you open your hands again afterward, the catch feels noticeably larger and more powerful, which is the point of the drill.

Should I use fins and paddles for technique?

Yes, used with purpose and in moderation. Fins build kick power and ankle flexibility and let you hold a faster, more streamlined position while working on technique. Paddles exaggerate the feel of the catch and reveal flaws when your stroke slips. A snorkel helps you focus on body position without breathing disruption, and a pull buoy isolates the upper body. Match the tool to the specific skill you are developing.
