A strong swimmer can still lose speed through a dropped elbow, a rushed breath, or a kick that creates more drag than propulsion. The right swim drills isolate those weak points so you can feel the correction, repeat it, and carry it into full-stroke swimming. Below, I break down the most useful exercises for freestyle, backstroke, breaststroke, and butterfly, plus a practical way to build them into a workout.
Small technique changes can produce faster, easier swimming
- Purpose drills should target one specific movement instead of replacing normal swimming.
- Freestyle improves with side balance, fingertip drag, catch, and controlled breathing work.
- Backstroke responds well to six-kick switch and single-arm drills that reinforce rotation.
- Breaststroke and butterfly depend heavily on timing, streamlining, and a patient recovery.
- Best practice is to use short repeats with clear feedback, then immediately swim normally.
What makes a technique drill worth your time
A useful drill exaggerates one part of the stroke without making the rest of the movement meaningless. I want to know exactly what I am practicing, what sensation I should notice, and how that change should appear when I return to full swimming. If an exercise leaves you moving slowly but teaches nothing you can transfer, it is probably just pool choreography.
Most drills fall into four groups. Some improve body position, others refine the catch or kick, while a third group develops breathing and timing. The most effective sessions combine one technical goal with enough normal swimming to check whether the change survives outside the drill.
Use feedback instead of guessing
Choose a simple measure before you start. It might be fewer strokes per length, quieter breathing, a more stable head, or the ability to hold your hips higher without extra effort. I also recommend swimming one easy length before and after each drill so you can compare the feeling while it is still fresh.
Equipment can help, but it should not hide the problem. A pull buoy can make body position easier to feel, fins can slow down the learning curve for kicking, and a snorkel can remove breathing distractions. None of them should become a permanent substitute for control without equipment.
Freestyle drills for balance, breathing, and a better catch
Freestyle usually improves fastest when the swimmer stops trying to move the arms harder and learns to reduce drag. I begin with balance and alignment, because a head that lifts or hips that sink will make every later correction more expensive.
Side kick with controlled breathing
Push off on one side with the lower arm extended and the upper hand resting on your thigh. Keep one goggle in the water, kick gently, and rotate just enough to breathe without lifting the head. Swim 4 x 25 yards, switching sides halfway through each length.
This exercise teaches the body to remain long while breathing. If your legs immediately sink, do not respond by kicking violently. Press the chest slightly into the water and keep the neck relaxed. The goal is a stable line, not a sprint.
Fingertip drag
During the recovery, lightly drag your fingertips across the surface from the hip toward the front of the stroke. The elbow stays higher than the hand while the shoulder rotates naturally. Try 6 x 25 yards at an easy pace, followed by 25 yards of regular freestyle.
I like this drill because it exposes a rushed recovery and a low elbow. It should not force an exaggerated shoulder lift. If you feel pinching in the shoulder, reduce the range and stop treating the exercise as a flexibility test.
Single-arm freestyle
Swim with one arm while the other remains extended in front or rests beside the body. Keep the kick quiet and focus on entering cleanly, setting the forearm vertically, and breathing without twisting the whole torso. Use 4 x 25 yards per side, then swim 50 yards normally.
The extended-arm version is easier for most swimmers because it provides a clear target for alignment. The arm-at-the-side version demands more balance and is better used after the basic pattern feels comfortable.
Backstroke drills that improve rotation and line
Backstroke gives you nowhere to hide from poor alignment. A head that rocks, knees that bend too much, or hips that drift sideways creates obvious resistance. I think of the stroke as a steady rotation around the body’s long axis, with the shoulders and hips turning together.
Six-kick switch
Start on your right side with the right arm extended overhead and the left arm resting beside your thigh. Take six relaxed kicks, then rotate smoothly to the opposite side and switch the arms. Repeat for 25 yards, keeping the head still and the hips close to the surface.
This drill teaches patience during the body roll. Many swimmers rotate from the shoulders but leave the hips behind, which makes the stroke feel disconnected. The switch should come from the whole body, not a sudden arm pull.
Single-arm backstroke
Keep one arm at your side while the other completes the stroke. Concentrate on a clean hand entry, a relaxed recovery, and a firm but not forced underwater pull. Swim 4 x 25 yards on each side with plenty of rest.
Because one arm is working alone, you can notice whether your body wobbles or your hand crosses the center line. That crossing is a common source of zigzagging. If you cannot keep a straight path, shorten the distance and slow the recovery.
Backstroke with pause
Pause briefly when the recovering arm reaches an upright position above the shoulder. This creates a moment to check that the opposite shoulder is rotated and the head remains neutral. Use it for 4 x 25 yards, but return to normal backstroke before fatigue changes your mechanics.
Breaststroke and butterfly drills for timing
Short-axis strokes are less forgiving when the timing is wrong. In breaststroke, the pull, breath, kick, and streamline must arrive in the right order. In butterfly, the body wave must travel through the chest and hips rather than being forced only by the knees.
Breaststroke pull with a narrow recovery
Swim using the arm action only while keeping the legs together and streamlined. Sweep the hands out, press the forearms back, breathe as the chest rises, then return the hands forward quickly. Add a light pull buoy if needed and perform 6 x 25 yards.
The lesson is not to pull as wide as possible. A broad sweep may feel powerful, but it often increases drag and delays the recovery. I look for elbows that stay controlled and hands that shoot forward before the body loses its line.
Two kicks, one pull
Perform one breaststroke pull followed by two breaststroke kicks, using the first kick to establish rhythm and the second to reinforce the finish. Keep the body streamlined between actions. Swim 4 x 25 yards with a relaxed pace.
This variation gives you time to feel the glide, which many swimmers rush through. The glide should be active rather than motionless. You are holding a narrow shape while allowing the previous kick to send you forward.

Single-arm butterfly
Use one arm for the butterfly pull while the other stays extended or rests at your side. Pair the arm action with a small, continuous dolphin kick and breathe forward only when the rhythm allows it. Start with 4 x 25 yards and stop before the movement becomes a heavy shoulder lift.
Butterfly is often overpowered. I would rather see a smaller wave, soft hands, and two connected kicks than a dramatic stroke that collapses after a few yards. If your lower back feels compressed, reduce the amplitude and keep the movement flowing from the chest.
How to place drills inside a real swim workout
Drills work best when they prepare you for swimming rather than replacing it. A practical session for a recreational swimmer might include a 300-yard easy warm-up, 8 x 25 yards of focused technique, 4 x 50 yards combining a drill with regular swimming, and a relaxed 200-yard finish.
| Training goal | Useful format | What to monitor |
|---|---|---|
| Body position | 6-8 x 25 yards with 15-20 seconds rest | Stable head, hips near the surface |
| Stroke timing | 4-6 x 50 yards as 25 drill and 25 swim | Whether the change transfers to full stroke |
| Breathing control | 6 x 25 yards at an easy aerobic effort | Quiet exhale and no head lift |
| Race preparation | 8 x 25 yards drill, then 4 x 50 yards at moderate pace | Technique under rising fatigue |
Rest long enough to preserve the movement. For most adults, 15 to 30 seconds between short repeats is more useful than forcing continuous lengths with deteriorating form. I usually place technical work early in the main set, then revisit the same idea later at a slightly higher effort.
Avoid changing five things at once. Pick one cue, such as “quiet head” or “finish the streamline,” and keep it for the entire set. When the stroke feels more natural, remove the equipment and test the movement under normal swimming conditions.
Mistakes that make good drills less effective
The most common mistake is turning a technique exercise into a conditioning contest. If you hold your breath, sprint every length, or kick until your legs flood with fatigue, the nervous system learns the wrong pattern. Quality beats distance when the goal is movement improvement.
- Going too fast hides balance and timing problems.
- Using fins constantly can make weak ankle control feel better than it really is.
- Overusing paddles may increase stress on the shoulders when the catch is not ready.
- Holding the breath creates tension and makes relaxed alignment harder.
- Repeating a drill without normal swimming prevents you from checking whether the change transfers.
Pain is different from productive effort. Stop any exercise that creates sharp shoulder, neck, knee, or lower-back discomfort. A coach, qualified instructor, or sports professional can help if a recurring limitation remains after you reduce the distance and intensity.
Turn one good drill into faster swimming
Choose a single weakness for the next two weeks and repeat the same drill in three sessions each week. Keep the volume modest, record one simple result, and finish every technical block with normal swimming. That is where the learning becomes useful.
My favorite test is uncomplicated. If the stroke feels quieter, the same pace requires fewer strokes, or breathing no longer interrupts the line, the exercise is doing its job. Keep the change that survives real swimming, and let the rest go.
