Freestyle problems rarely stay fixed forever. Sinking legs can return when you are tired, crossover often shows up when you breathe under pressure, and a weak catch can hide inside an otherwise decent stroke. This guide gives you a simple troubleshooting system: identify the symptom, match it to the likely cause, and use a small group of freestyle drills that directly target the issue. Save it and return to it whenever your front crawl feels less balanced, less connected, or less effective than it should.
Overview
If you want better freestyle, you usually do not need more random drills. You need the right drill for the right mistake. That is the main idea here.
Three of the most common freestyle issues are:
- Sinking legs: your hips ride low, kicking feels heavy, and holding pace takes too much effort.
- Crossover: your hand enters across the center line, which can make the stroke snake side to side and overload the shoulders.
- Poor catch: the hand slips back without holding much water, so your pull looks busy but does not move you forward well.
These problems often overlap. A swimmer with sinking legs may press down with the lead arm, which then disrupts body line and makes the catch weaker. A swimmer who crosses over may also lose a clean line from entry to extension, making rotation less stable and breathing more rushed.
That is why the best freestyle drills are not just technical exercises. They are correction tools. Each drill should teach one clear sensation:
- How a balanced body line feels
- Where the hand should enter and extend
- What it means to hold water early in the stroke
As you work through this guide, focus on outcomes you can feel in the water: quieter kick, straighter travel, easier breathing, and more pressure on the forearm during the catch. Those signals matter more than doing a drill perfectly on paper.
Core framework
Use this framework every time your freestyle feels off: symptom, cause, drill, and transfer. In other words, notice the problem, guess the simplest cause, choose one drill, then swim normally and see if the improvement carries over.
1. Fix sinking legs by improving line before you kick harder
Many swimmers try to solve sinking legs with a bigger kick. Sometimes that helps, but often the real issue is balance. If the head is too high, the chest is tense, or the lead arm presses downward, the hips will usually drop.
Key cues:
- Look down, not forward
- Let the chest rest slightly into the water
- Keep the spine long and the neck quiet
- Kick from the hips with small, steady beats
Best drills for sinking legs
Superman glide: Push off with both arms extended, face down, and hold a long line for a few seconds. The goal is not distance. The goal is to feel the hips stay near the surface when the head stays neutral and the core stays long.
6-kick switch: Lie on one side with the lower arm extended and the top arm resting by the hip. Take six controlled kicks, then switch sides with one stroke. This teaches side balance, a narrow kick, and stable hips.
Kick on side with one goggle in, one goggle out: This adds breathing control to body-line work. If the head lifts too much, the hips usually drop right away, which makes the feedback immediate.
Pull with a snorkel and light buoy: Used carefully, this can help you feel a level body line without the disruption of breathing. The snorkel removes head movement; the buoy reduces the urge to overkick. Keep the pressure relaxed and avoid depending on the buoy long term.
Transfer set: After 4 x 25 drill, swim 4 x 50 easy to moderate and try to keep the same low-effort body position. If your legs sink again during normal swimming, return to a shorter repeat and rebuild the feeling.
2. Fix crossover by cleaning up entry, extension, and rotation
Crossover happens when the hand enters in front of the head or crosses the center line during extension. This often creates a fishtailing stroke. You may feel your legs swing side to side, especially when breathing.
Key cues:
- Enter in line with the shoulder, not the nose
- Reach forward, not across
- Rotate the body as a unit instead of throwing the arm across
- Keep the kick narrow so it supports alignment instead of reacting to it
Best drills for crossover
Catch-up with center-line awareness: Swim catch-up freestyle, but focus only on hand entry. Imagine railroad tracks extending forward from each shoulder. Each hand should travel on its own track. This is one of the simplest swim crossover drill options because it slows the stroke enough to make the path visible.
Single-arm freestyle: Swim with one arm while the other stays at your side or extended forward. This helps isolate the entry and extension path. Breathe to the stroking side first, then repeat without breathing every stroke so the head does not pull the hand inward.
Fingertip drag: During recovery, lightly drag the fingertips across the surface. This encourages a relaxed, controlled recovery and often reduces the wide swing that turns into a crossover at entry.
Lanes, lines, or visual targets: Use the black line on the bottom of the pool and imagine two tracks just outside it. Your hands should enter and extend on those tracks. Many swimmers improve simply by giving the stroke a clearer map.
Transfer set: Swim 6 x 50 as 25 single-arm drill plus 25 full freestyle. On the full swim, keep the same shoulder-width entry. If breathing causes the hand to cross over, breathe less often for a few lengths and restore the line before returning to normal breathing.
3. Improve the catch by learning to hold water early
A poor catch usually looks like pressing down, dropping the elbow, or starting the pull too late. The result is low propulsion and a stroke that feels disconnected from the body roll.
Key cues:
- Set the hand and forearm early
- Keep the elbow relatively high compared with the hand
- Press water back, not down
- Connect the catch to rotation and core tension, not just arm strength
Best drills to improve swim catch
Sculling in front: With arms extended in front, angle the hands and forearms to feel pressure on the water. The motion is small. You are not trying to travel fast. You are teaching the forearm to become part of the paddle.
Dog paddle with high elbows: Swim short repeats with an underwater recovery and focus on keeping the elbow out in front as the hand and forearm catch. This is one of the best front crawl technique drills for feeling an early vertical forearm without overthinking it.
Front scull to freestyle: Start with a few seconds of front scull, then transition directly into smooth freestyle. This makes it easier to carry the feeling of pressure into the first strokes.
Fist drill: Swim with closed fists to reduce the hand surface area. This encourages you to use the forearm and improve awareness of the catch. Keep repeats short so the stroke does not fall apart.
Paddle work, carefully: Small technique paddles can highlight whether you are holding water cleanly, but they can also mask flaws or stress the shoulders if used too early. Use them only when your entry and catch mechanics are reasonably stable.
Transfer set: Try 8 x 25 as 12.5 scull or dog paddle plus 12.5 swim. Focus on whether the first full strokes feel more solid and connected. If they do not, shorten the drill segment and simplify the cue.
4. Use one focal point at a time
Most swimmers stall because they try to fix the whole stroke at once. Choose one problem per session. If your legs sink and your catch is weak, start with body line first. Once the body is more level, the catch usually becomes easier to organize.
A useful order is:
- Body position and balance
- Entry and alignment
- Catch and pull pressure
- Breathing timing under normal pace
This sequence works because freestyle is easier to correct from the front of the stroke backward. A clean line sets up a cleaner catch.
Practical examples
Here are simple practice templates you can use right away. Each one is short enough to add to a normal swimmer workout without turning the entire session into drill work.
Example 1: For sinking legs
Goal: learn how to fix sinking legs swimming through balance, not force.
- 4 x 25 Superman glide to easy swim
- 4 x 25 6-kick switch
- 4 x 25 side kick with controlled breath
- 4 x 50 freestyle easy to moderate, hold a quiet head and light kick
What to watch for: bubbles behind the feet should stay narrow, and the hips should feel supported instead of dragged.
Example 2: For crossover
Goal: stop crossing the center line and swim straighter.
- 4 x 25 catch-up with shoulder-width entry
- 4 x 25 single-arm freestyle right
- 4 x 25 single-arm freestyle left
- 4 x 50 full freestyle, breathe every 3 or by pattern that does not disturb alignment
What to watch for: the stroke should feel quieter from side to side, with less fishtailing through the legs.
Example 3: For poor catch
Goal: improve swim catch and create more pressure early in the pull.
- 4 x 25 front scull
- 4 x 25 dog paddle with high-elbow focus
- 4 x 25 fist drill
- 6 x 50 freestyle at moderate effort, count strokes and hold consistent pressure
What to watch for: fewer rushed arm cycles and a stronger sense that each stroke moves you forward.
Example 4: Mixed correction set for masters or self-coached swimmers
This works well as a repeatable technique block inside a masters swim workout or solo session:
- 200 easy swim
- 4 x 25 body-line drill of choice
- 4 x 25 alignment drill of choice
- 4 x 25 catch drill of choice
- 6 x 50 as 25 drill plus 25 swim
- 4 x 100 freestyle smooth, holding the best cue from the set
If you only swim one to three times per week, this kind of focused block is often more useful than adding extra volume. For broader scheduling ideas, see Weekly Swim Training Plan for 1, 2, 3, and 4 Days per Week.

Common mistakes
A good drill can still fail if you use it the wrong way. These are the most common errors swimmers make when trying to correct freestyle mechanics.
Doing drills too fast
Speed hides detail. If you rush a drill, you usually reinforce the same habit you were trying to fix. Slow down enough to feel what changed.
Using too many tools at once
Fins, paddles, snorkels, and buoys can all help, but stacking several tools together can remove the feedback you actually need. Start with the simplest version of the drill and add equipment only if it clarifies the movement.
Practicing the drill but not the transfer
The drill is only the first half of the work. You need to swim normal freestyle right after it and test whether the improved pattern carries over. If not, the drill may be too complex, or the cue may be wrong for you.
Changing multiple cues in one repeat
“Head down, elbow high, faster kick, wider entry, stronger pull” is too much for one length. Pick one main correction. If the stroke improves, keep it. If not, switch the cue, not your entire approach.
Ignoring breathing as a trigger
Many freestyle flaws only appear when you breathe. Legs sink, the hand crosses over, or the lead arm presses down. Always recheck the stroke during breathing lengths, not just while swimming with your face down.
Using stroke count without context
Lower stroke count is not always better. If you glide too long or flatten out to take fewer strokes, you may lose rhythm and connection. Count strokes as feedback, not as the only goal.
If you want more objective self-checks, video can help. A short side and front clip is often enough to reveal crossover, head position, or catch timing. For a broader look at practical analysis options, see Motion Analysis for Swimmers: Affordable Tools to Check Your Stroke Outside the Pool.
When to revisit
This is not a one-time article. Freestyle technique changes with fatigue, fitness, training load, and goals. Revisit these drills whenever one of the following happens:
- Your pace stops improving even though fitness is better
- Your stroke feels more tiring at easy speeds
- Breathing to one side starts to pull the stroke apart
- You return from a break and body position feels off
- You add speed work and old technical flaws reappear
- You move from pool swimming toward open water or triathlon training
A practical review cycle is simple:
- Choose one symptom from your recent swims
- Pick one drill from the matching section
- Use it for two to three sessions
- Swim a short repeat set and note whether the change transfers
- Keep, adjust, or replace the drill based on what you actually feel
If you want an easy action plan, start your next session with this 15-minute reset:
- 200 easy freestyle
- 4 x 25 for body line
- 4 x 25 for alignment
- 4 x 25 for catch
- 4 x 50 smooth swim, choosing one cue only
Then write down one sentence after practice: What felt better, and when did it disappear? That note is often enough to guide your next visit to this troubleshooting guide.
Freestyle improves fastest when the correction is specific, repeatable, and revisited as needed. Keep this article as your reference point: sinking legs call for balance work, crossover calls for cleaner entry and extension, and poor catch calls for better pressure on the water. When the stroke goes off, you do not need to start over. You just need the right drill for the right problem.
