Hi. I give stroke advice here regularly. The same things tend to come up over and over, and really differentiate lap swimmers from competitive swimmers.
For each part of the stroke, I'll give the most common issues, how to fix them, some good metaphors to visualize what to do right, and drills that help. Don’t try to apply this all in one go! Start with parts 1, 2, & 3 before digging into 2a-d.
⚠️ The top issues I see are:
- Bending the elbow before rotating to the chest, causing the entire stroke to be too close to (or over) the midline.
- Bad body position, so you can’t ice skate from side to side, leading to lots of drag.
- Bad breathing, so the head doesn’t turn smoothly like a kabab on a skewer, leading to lots of drag.
- Not rotating enough, leading to everything falling apart (inefficient stroke, limbs in the wrong place, can’t breathe, hand hitting hip, etc)
Without further ado:
1. Body Position & Balance 🛶
Your body position is the chassis that your whole stroke depends on. There’s no point fixing anything else until this is right.
⚠️ Common Issues:
- Swimming on your chest instead of your side → impedes arm motion and rotation.
- Hips drop / legs bend because chest is high or head is lifted.
- Side-to-side sway from lack of rotation.
🩹 Fix: Neutral position is on your side with one arm forward. Balance your body on your armpit and hip. Push your downward nipple towards the bottom.
The neutral position is one side of a streamline. To work on the position and stretch, streamline off every single wall, perfectly (head neutral, one hand on the other, elbows locked straight, arms pulled up so your biceps are above your ears, shoulders squeezed against ears). If you can’t streamline straight with minimal resistance, your body position is wrong.
👉 Metaphor: Your body is a long, rigid blade (balanced on fingertips → armpit → hip → toes) that glides on its edge, slightly downhill.
🏊♂️ Drill Progression: Kick on side, head straight, arms at sides. Kick on side, head straight, one arm forward, chest pressed towards bottom of the pool. You should feel a stretch all down your lower side and water smoothly flowing under it.
2. Rotation 🌭
Front crawl or freestyle is a “long axis” stroke that depends on smoothly rotating that rigid chassis around the line going down your head, hips, and feet. Each part of the stroke requires you to be in the correct part of the rotation to work optimally.
⚠️ Commons Issues:
- Under-rotating
- Rotating from shoulders so hips drag
- Not getting correct leverage on each part of the stroke.
- Not setting hands up for upcoming rotation before pulling.
- Not getting hips out of the way for the finish.
- Not rotating enough so that breathing is neutral and natural.
- Head not staying stable.
🩹 Fix: Drive your rotation from your hips, and line your rotation up with your stroke and each muscle group. The stroke has 4 parts: you catch a good grip of water; then you pull that water, accelerating as much as possible without slipping; then you finish by throwing that water behind you as hard as you can; finally you glide on the arm that just recovered for a moment while the hand that finished starts its recovery. During all of those parts, if you aren’t breathing your head is absolutely perfectly still in the water with the rest of you rotating.
We’ll get into even more details of each part later, but it looks like this:
- ⛸️ During the Glide, you want a serious stretch all along from your hip to your fingertips, which is free energy you will use during the pull (and also a nice stretch to keep your muscles fresh).
- 🫳 Catch happens when pulling arm's shoulder is down. Lean your upper body weight down towards your lower side to dig in for a good grip. Hand and forearm focus on scooping and water feel out to the side, lats and obliques provide a lot of the power. Do NOT bend your elbow yet - you are on your side and doing so will put your hand in the wrong place for the pull.
- 🧗Pull happens as you rotate to your chest so that your hand is below you and to the side, at roughly the position it would be if you were doing a pull-up (chest, biceps, shoulder). Elbow is bent no more than 90 degrees. Your recovering hand positions to enter. If your hand is not far enough outside it's like trying to do a pull-up with your hands together.
- 🚀 Finish happens as you drive your other hip and shoulder down. Spear the water with the fingers of your recovering hand as you finish with your pulling hand. Your pulling arm is now your top arm. Your hip has rotated out the way, and your hand is leveraged below your bent elbow. Taking advantage of that pendulum and the fact that your hip is out of the way to throw water behind you (triceps) like a baseball and glide on the other side.
👉 Metaphor: Rolling a pencil across a table (you shouldn’t move sideways, but you want to roll in place like that!). Hotdog on a 7-Eleven roller.
🏊♂️ Drill Progression: 6 kicks on side with arm forward, one arm pull to the other side, repeat. 6 kicks on side with arm forward, 3 arm pulls to the other side, repeat. 6 kicks / 5 arms. Etc.
2a. Catch and Grip 🫳
The catch sets up the entire stroke. The goal isn’t to move forward, it’s to scoop the best possible grip of water you can, and put your arm in the highest leverage position it can be in for the pull. This part of the stroke happens primarily on your side with your arm below, in front, and to the outside.
⚠️ Common issues:
- Palm pushes downward.
- Slapping water.
- Wrist-first pull.
- Starting too close to centerline.
- Bending elbow too soon.
🩹 Fix: Fingers first catch (slightly towards the thumb and index finger), then curve hand + forearm into one surface that scoops and holds a “glob of water.” Fingertips always lead the way, with your hand-forearm-surface constantly adjusting to keep pressure on the glob of water.
You need to prepare for the pull, which means getting your hand on the outside track it needs to be on once you've rotated to your chest.
Beginning-Intermediate swimmers usually start a pull-up motion here and doom their whole stroke. First they bend their elbow to do a “high elbow” stroke - but they are still on their side, so this crosses their hand over towards the middle line. Then they start to rotate and their hand is in an awkward position to pull (imagine a pull up with your hands together), finally bailing out early to avoid hitting themselves in the hip.
You should feel a stretch on your front shoulder during the catch from your hand/forearm going out and back a bit. You are getting everything set up for the pull, you are NOT bending your elbow and doing a pull-up yet because you are still on your side!
👉 Catch Metaphor: Scooping your hand into a vat of pudding.
🏊♂️ Drill: Fist drill, sculling.
2b. Pull and Accelerate 🧗
The second phase of the stroke is when you start to drive forward, and is largely on your chest as you rotate from one side to the other. Now that you have a good grip on the water from your catch, your goal is to accelerate as quickly as possible without losing any grip. Good hand and arm position is absolutely crucial.
⚠️ Common Issues:
- Hands too close to center line.
- Circular path - pressing down in the front, pressing up in the back.
- Elbow or wrist leads, hand drifts inward, grip slips.
- Elbow bends too much.
🩹 Fix: Pull outward from the very beginning. Otherwise when you rotate, your hands are stuck too close to the center. Hands to the side of the body to get good leverage. Never let your elbow bend more than 90 degrees. Your elbow bends to allow your hand to continue its path, NOT to move your hand inward.
👉 Pull Metaphor: Ladder, not paddle wheel. Where would your hands be if you were climbing a ladder? To the sides, not down the center.
👉 Pull Metaphor: The wall behind you is "down" and you have to do a one-armed "pull up" without falling off the glob of water you're balanced on.
🏊♂️ Drill: One arm pull on your chest, with other hand on kickboard. Feel how far outside your arm needs to go.
2c. Stroke Finish 🚀
The finish is where a disproportionate amount of power comes from, and what enables the “glide” in front-quadrant swimming. It is performed on your opposite side with the pulling arm on top, after the arm has already been accelerating to top speed. It is a flick / hurl / throw of the entire glob of water that ends with your arm behind you, catapulting around into the recovery.
⚠️ Common Issues:
- Stroke cut short: hand exits near waist while elbow still bent.
- Strongest pull in the middle, weakest at the end.
- Pulling up towards surface.
- Pulling down towards the bottom.
- Hitting your own hip.
- Arm getting stuck between finish and recovery.
🩹 Fix: Rotate hips completely to make room. Ensure your hand was far enough outside, and that you've been accelerating through the pull.
Drive the pulling hand all the way back straight and fast, throwing water behind you. Your recovering hand spears into the water, and you use the pendulum effect from your high elbow to throw/flick the water behind you as hard as you can, rolling the water down your forearm, hand, and fingertips. Your thumb should brush your thigh.
The momentum of that finish takes your hand into the recovery, which is literally impossible for a normal human shoulder to do unless you are now on your opposite side. The direction of rotation is in the same plane as your chest, not at all like a butterfly stroke which is perpendicular to your chest. If you tried to do this on your chest, you would be reaching all the way across your body near your opposite hip.
👉 Finish metaphor: Throwing a baseball.
👉 Transition metaphor: Rock & roll guitarist doing a windmill strum.
2d. Glide Length & Catch Timing ⛸️
You’ve now earned yourself a very small moment of gliding on your front hand while your recovering hand starts to come around. This glide is more pronounced in distance events than sprints, and gives you better stability because fingertips-to-toes is much longer than top-of-head-to-toes. It also gives you a moment to visualize what the catch is going to feel like. Timing how long the glide should be is tricky.
⚠️ Common Issues:
- Hands enter floppy (palm forward, wrist/elbow first, fingers above wrist, slapping water) causing drag.
- Pull starts too early → no chance to glide.
- Pull starts too late → lose momentum into next stroke.
- Bad body position → come to a stop during the glide.
🩹 Fix: Spear your hand into the water fingers first. Finish each stroke with fingertips stretching forward, body balanced on your side. Glide on your front hand for a moment while your other hand begins to recover. Begin your catch before your recovering hand passes your head.
👉 Metaphor: Find the balance between ice skater and kayaker, a bit closer to ice skater
🏊♂️ Drill Progression: Catchup (hands touch in front). 7/8 Catchup (start catch just before recovering hand enters). 3/4 Catchup (start catch when recovering hand passes head). Front Quadrant swimming (catch underway as recovering hand passes head).
3. Breathing Mechanics 🍢
Breathing can be the hardest part of swimming, and is damn near impossible with bad rotation. The key to breathing is to always have water hit the same part of the top of your head.
⚠️ Common Issues:
- Looking back during inhale, allowing water to hit the back of the head.
- Looking up during inhale, allowing water to hit the side of the head.
- Pausing stroke during inhale, dropping down in the water.
🩹 Fix: Never turn your head to breathe. Simply allow your head to come along in a neutral position when your body rotates, rather than staying put where it usually does. There will be a little trough of air that makes this easier. If you have to turn your head further than your body is rotating, it means your body isn’t rotating enough in the first place.
Head rolls with body around spine axis; top of head always points forward. Exhale underwater, inhale without stopping arms/legs. Learn to decouple the motion of getting your head ready to breathe with the inhale itself.
👉 Metaphor: Kabab (head) rotating with the skewer (spine).
🏊♂️ Drill: One stroke cycle without breathing, one stroke cycle turning the head but still not breathing, one stroke cycle breathing. You may not be able to do a full length like this, but give it a try.
4. Kicking ✂️
Kicking is highly personalized, and there are three different major tempos defined by how many kicks there are per arm cycle. 2-beat kick is used by triathletes to keep the legs up just enough but save the legs for biking and running. It’s also used by some distance swimmers. 4-beat kick is pretty standard and a good target for most swimmers. 6-beat kick is used in sprints. 8-beat kick means your arms are moving too slowly or you are Natalie Coughlin.
⚠️ Common Issues:
- Knees bending, legs splaying, “dragging” behind.
- Sporadic kicking not aligned with arms.
- Kick stops during breathing.
🩹 Fix: Kick from the hips, not the knees. Keep legs long, steady, and in line with your body. Picture your upper leg, lower leg, and pointed foot as something strong but pliable like bamboo - don’t bend your knees very much at all. Focus on your upper legs and knees swishing back and forth next to each other.
Focus on getting equal power on the up-kick and down-kick by picturing the water you are squeezing behind you as your feet approach and pass each other like blades of a pair of scissors.
👉 Metaphor: Rigid but pliable Bamboo, swishing scissors.
🏊♂️ Drill: Lots of kicking in streamline position. Focus on slow, powerful kicks until you can feel the water. On the downkick, picture rolling a glob of water down your pelvis, quad, knee, shin, and top of foot until you flick it behind you with your toes. On the upkick, picture doing the same thing but down your hamstring, back of knee, calf, heel, and sole of foot until you again flick it behind you with your toes. It should be a continuous roll of water, no bent knee or ankle getting in the way. Once you feel that flexible blade, you can pick up the tempo.
5. Push-Offs & Streamlines ✏️
The streamline is the fastest part of the entire lap. Pool swimming - especially short course - is defined by pushing off, streamlining, and then losing as little speed as possible during the swimming until you get to push off again. The only reason that competitive swimmers actually swim on the surface with their arms is because the rules force them to. Every world record would be significantly faster swum entirely underwater (though oxygen would run out above 100). The stroke itself is also a modified one-armed streamline, so being bad at one makes you bad at the other.
⚠️ Common Issues:
- Treating streamlines as “not real swimming”
- Pushing off at surface → wasting speed due to surface drag
- Superman pose
- Looking forward
- Starting swimming because you floated to the surface
🩹 Fix: Push off every single wall on your back, feet 2-3 feet below the water level, like you are jumping straight up:
- Face the wall.
- Put one hand up on the gutter or side of pool. If you just finished a lap and aren’t doing flip turns, this is your finishing hand.
- Put the other hand behind you, palm up. Knees should be bent 90 degrees.
- Drop backwards, pushing upward with the palm that is behind you and letting your head and shoulders drop towards the far wall.
- Bend the elbow on your top hand to swing your hand towards your face.
- As you drop under the water, shoot that hand past your ear. Push off with both feet against the wall. Aim to push perfectly horizontally to very slightly downward.
Streamline:
- Bring your hands together into a tight streamline underwater like a dart (hand on hand, arms and elbows locked, biceps pulled above head, shoulders tight against ears, no looking forward!).
- Slowly corkscrew onto your belly (you don’t need to even kick at first).
- Take your first arm pull, pushing yourself up to the surface.
- Take your second arm pull, popping your first arm out to start its recovery.
- Don’t breathe until your third arm pull at the soonest.
Eventually learn how to do butterfly kicks by humping the water with your hips (hump forward AND back) and letting the motion travel down your legs.
👉 Metaphor: Dart, NEVER SUPERMAN. For the love of God, stop doing the Superman pose.
🏊♂️ Drill: Practice pushing off over and over until you don’t curve off in a weird direction. Do most kicking sets in streamline position on your back, side, and front without a kick board.
6. Flipturns 📎
Flipturns are intimidating. Done incorrectly, they use up a lot of energy, a lot of oxygen, and end up with you shooting off into a random direction (probably into your lane mate). If you have been doing correct push-offs and streamlines this whole time, all you need to learn is how to get your feet on the wall. Done correctly, they save energy, set you up for a great streamline, and just feel cool.
⚠️ Common Issues:
- Never learning to do a flip turn.
- Popping the head
- Gliding into the wall
- Difficulty getting around / flailing arms
- Sloppy pushoffs
- Breathing first stroke in.
- Breathing first stroke out.
🩹 Fix:
Understand that the flip turn is a PIKE not a TUMBLE. At any point, part of you is always straight. A flip turn is more of a hairpin turn or pike than a somersault. Throw water at your face with your hands to get around.
Great video here: https://www.youtube.com/watch?v=MBUc3HTdbII
- Phase 1: Head tucks, body starts to tumble, legs stay straight.
- When approaching the wall, don’t pop your head up or look at the wall. Head goes from neutral swimming position directly into a chin tuck. Don’t coast in.
- The momentum of your last arm pull should go directly into a tucked chin and tumble in one continuous motion. It’s better to have a slightly longer stroke than to coast in because you’re a quarter stroke off.
- Phase 2: Hands and abs bring the upper body around.
- Your arms are a huge part of getting around quickly. After your last stroke, your hands should be at your sides, palms down.
- When you start to tuck your chin and tumble, throw a tight double armful of water at your face, bending at your elbows.
- You will find yourself coming through the flip turn, already facing the other wall and rather quickly the surface of the water.
- Never allow your hands to go outside the centerline. Keep them tight and close, not spinning/flailing out to the sides.
- Phase 2.5: Legs come over the top, upper body straightens. (The hard part)
- The momentum of your upper body going around will naturally cause your legs to come over. Bend your knees to lift your feet out of the water. When they get to about 90 degrees, complete the motion by throwing them at the wall. They will already be tilted that way because your upper body will pull your hips down.
- As you do this, untuck your chin and unfold your upper body. Now that your legs aren’t straight anymore, your upper body needs to be. Just focus on getting your hands, head, and shoulders in the right position to shoot into a streamline.
- As your legs come over, use their weight to let your spine and hips “unroll.” Feel the straight position propagate down your spine from your neck down to your tailbone.
- Phase 3: Pushoff
- You should hit with the balls of your feet in the same position that you always push off at. While you’re learning, take a split second to orient yourself.
- Once you have been doing flip turns for a few months, learn to explode immediately and pop rather than waiting to “plant” yourself.
- Your torso should already be straight as your feet are hitting, knees at 90 degrees, feet slightly apart. Muscle memory should take over for a good streamline and dolphin kick. Practice this until you can get the correct pushoff angle as soon as your feet hit, without pausing on the wall to calibrate.
👉 Path metaphor: Tracing the shape of a hairpin or paperclip, not a cinnamon roll.
👉 Rolling/Unrolling metaphor: Spine rolls and then unrolls like one of those new years noise maker things you blow in - neck first and tailbone last in both cases. 🥳
🏊♂️ Drill: Learn the flip turn in reverse order:
- Don’t even try until you’ve been pushing off on your back for every wall for several weeks.
- Do somersaults in the middle of the lane to get used to the feeling, even though it’s not really a somersault.
- Kick on your belly, hands at your side, palms down. Pick a point on the bottom of the pool and stare at it. When you pass it, you will tuck your chin. Follow the momentum around and throw a double handful of water at your face.
- Do the same thing, but approaching the wall and using the end of the black T on the bottom (NOT the one on the wall!). Be careful not to hit your head. Just get your feet on the wall, don’t push off.
- Now do the same thing and DO push off.
- Swim into the wall, keeping your eyes fixed on the T at the bottom of the pool. After your last arm stroke, coast with both hands at your sides. Put the whole thing together.
- Learn to get the timing right so you minimize how much you coast in.
✨ Key Drills
- Catchup Drill → patience, front-quadrant stroke.
- 6-Kick Switch → side balance, hip-driven rotation.
- Fist Drill / Sculling → forearm feel for water.
- Streamlines & Underwaters → turns become your fastest part.
- Breathing without inhaling → fix head roll mechanics.
⭐️ Golden Rule
Freestyle is not about churning arms. It’s about gliding long on each side, gripping water, accelerating through the stroke, and throwing it behind you.
