A free course I put together for adults who can already swim a bit, but stall out after 50 or 100 metres. The end goal is a relaxed 30 minutes, or 1,500 m, of continuous freestyle. The course features the Slipstream portable swim machine, one of the more useful tools I’ve come across for practising freestyle in a home-sized pool. In full disclosure: Slipstream offered me and all Yousuli members a discount, and I’ve been using one two or three times a week in the months I spent building this course, mostly because it’s convenient. Read straight through if you have an hour, or jump to whichever stage matches where you are.
Worth checking before you sink an hour into reading.
One target, so we both know what we’re aiming at.
A relaxed 30 minutes, or 1,500 m, of continuous freestyle. It doesn’t have to be fast, and it doesn’t need to be perfect, but I do want it to look reasonably good. A clean-looking stroke usually means the basics are there: sustainable breathing, a body that holds its line in the water, and a stroke that doesn’t fall apart by the back end of the swim.
It’s a modest target on purpose. Once you’re comfortable there, a lot opens up: most sprint and Olympic triathlons, open-water swims at most lakes and parks, joining an adult swim club without your stomach in a knot, plain fitness swimming for the rest of your life. From that point on, you build instead of survive.
Speed in swimming comes from efficiency more than from effort. If you push hard on a stroke that’s broken, you end up slower and more exhausted than someone half as fit who’s swimming cleanly. So we fix the stroke first. The pace shows up on its own once the mechanics are there, and it keeps improving for years after a course like this ends.
Each one assumes the one above it is already in place. Resist the urge to skip ahead, even if a later stage sounds more interesting.
First thing, before any stroke work: can you actually float? A lot of adult swimmers I work with are fighting gravity the entire length, legs sinking, head pushing up, and that alone is why a short swim already feels hard. So we start with the float, the head position, and the simple awareness of where the water is pressing on you.
The other piece of stage 1 is CO2 tolerance. Most beginners aren’t running out of oxygen when they panic-stop, they’re running out of patience with rising CO2. A few minutes a day of box breathing on land (5 in, 5 hold, 5 out, 5 hold) trains the same nervous-system response we need in the water.
Breathing is what splits a comfortable 1,500 m from a panicky 200 m. The most common mistake I see is holding your breath while your face is in the water, then trying to exhale and inhale in the brief moment your mouth comes out. It doesn’t work, you end up half-empty and gasping.
The fix is to exhale continuously through the nose while your face is in the water. By the time you turn to breathe, your lungs are already empty and the inhale takes care of itself. We build up to bilateral breathing (every three strokes) once the exhale is dependable.
Now we talk about how you actually move forward. Most beginners pull with a dropped elbow, which means they’re shoving water down and sideways instead of pushing it backwards. We work on a high-elbow catch using a snorkel, so breathing isn’t a distraction, and paddles like the FINIS Freestyler, which yank sideways the second the elbow drops.
You’ll know stage 3 has clicked when a pull starts to send you forward instead of just tiring your shoulders. It feels almost lazy when it’s right.
At the pace we’re aiming for, the kick is mostly there to keep you balanced, not to push you forward. A common pattern with adult swimmers is to overkick, which burns the legs and barely changes the speed. What we want is a quiet 2-beat or 4-beat kick coming from the hip, with relaxed ankles.
Ankle mobility is the limiter most people don’t know they have. Cyclists and runners especially carry stiff ankles, so a little dry-land mobility work goes a long way here.
By stage 5, the body position, the breathing, the catch and the kick are all roughly in place. The job now is to keep them in place over more and more distance. The tempo trainer earns its keep here: a beep at your chosen stroke rate, and you just try to land on it, set after set.
The progression looks like 5 × 200 m turns into 4 × 300, then 3 × 500, then a straight 1,000, then a straight 1,500. The stroke shouldn’t change at all between any of those, only the distance does.
This one’s optional. If your end goal is just to swim 30 minutes for fitness, you can stop at stage 5. If you want to race a triathlon, swim open water, or join a masters squad, stage 6 is the bridge: sighting, mass-start nerves, cold-shock acclimation, basic wetsuit feel. I don’t go very deep here, that’s a course on its own, but we point you at the right things to practise.
This is also the point where I’d suggest getting a coached session or two if you haven’t already. Self-coaching gets you most of the way, but somebody watching can save you a lot of guessing.
The full set, grouped by the stage they belong to. Each one has a short video and a reason it exists. You shouldn’t be doing all of them in one swim. Pick two or three for the day, the ones that match the stage you’re on.
Floating flat, head where it belongs, awareness of how the water is pushing on you.

Most drills take 5 to 10 minutes of focused work in a session. You don’t need to master all 21. You need to pick the right one for where you are and pay attention to what it’s trying to teach you.
You don’t need all of these, and none of them are mandatory. They speed things up at the right stage. The wrong tool at the wrong moment just gets in the way.
Takes breathing out of the equation so you can put all your attention on body position, head alignment, and the catch. If I had to pick one item to own, this would be it. FINIS makes the standard, plus a smaller swimmer’s version for narrower faces.
The classic. Isolates the kick so you can work on body position and the basic flutter without anything else getting in the way. Hold it loosely, your hands and forearms shouldn’t be gripping. Pairs well with short fins for beginners who need a little help staying horizontal.
The pivot shape rewards a high-elbow catch and yanks sideways when the elbow drops. The paddle gives you the feedback before any coach does. Much better for technique than flat power paddles, which just pile load on the shoulders.
They give you a bit of speed in the water and, more importantly, encourage ankle mobility and kicking from the hip. Avoid the long, stiff fins, they distort the kick and don’t carry over once you take them off.
Floats the legs so you can focus on the upper body and rotation. It’s great paired with the snorkel for technique sets. Just don’t live in it, your legs still need to remember how to swim.
Cheap, and more useful than it has any right to be. Set a beep at your target stroke rate and try to land on it. You can also use it as a pacer, one beep per 25 m, on the longer continuous sets later in the course.
A small rubber loop around the ankles that takes the legs out of the equation. Forces you to swim with the upper body alone, which exposes any leftover body-position issue immediately. Used sparingly at the back end of stage 5 to test how clean the stroke really is. If you can swim 50 m with the band, the basics are landing.
A wrist-mounted positioner that holds the forearm in a high-elbow catch shape. Useful once you have the basic catch and want to lock it in under fatigue. More a polishing tool than a foundation one, which is why it lives in stage 6.
Worn on the torso, gives you an audible tick when your body rotation hits the right angle from side to side. Rotation is one of the last things to settle in, and Tech Toc lets you train it without needing a coach in the lane. Useful at the back end of the course, not at the start.
If your end goal is open water or triathlon, you’ll want one. The buoyancy lifts the legs and the rubber makes you feel faster, which is honestly a confidence boost on its own. Just be aware it can paper over a poor body position, so don’t use it as a crutch in the pool.
Have two pairs you trust, one clear or low-light tint, one darker for sunny outdoor swims. Replace them once the seal starts going. Leaky goggles will ruin a session that no amount of technique work can fix.
The course assumes you can get access to a Slipstream swim station. Here’s why that’s the case.
Slipstream is a battery-powered, portable swimming machine. A turning vane plus a horizontal conditioning grill push out a wide, deep, even current in any pool. Drop it in a small backyard or hotel pool and you’ve got a proper swim station for the session. 11 speed settings. Top end edges toward 1:20 / 100 yd, and a full battery covers roughly an Ironman swim (~3.8 km) at the working speeds.
Curious which speeds map to which pool paces? There’s a working operational chart on the swim-coaching page → covering speeds 7 to 10 with rough yd / m pace equivalents and a confidence note.
Swimming in place means no flip turns breaking your rhythm, no other swimmers in your lane, and no losing the cue at the wall. A coach (or a camera on a tripod) can walk around you and watch the stroke from every angle. For a drill-heavy course like this one, that adds up to a lot more useful repetitions per hour.
Two ways. Either buy your own Slipstream for your home or community pool (the Yousuli member discount lives behind the YSC members page, joining the free tier unlocks it), or book an on-site swim lesson with me and I’ll bring mine along to whichever pool we use.
YSC membership is free on the entry tier. The Performance Tier ($99/yr) adds partner discounts on more Yousuli gear, plus the race-day fueling planner and the calculators with saved results.
Reading these and nodding is easy. Spotting yourself doing them mid-set is the real work.
If I had to pick one habit that wrecks beginner swims, it’s this. Exhale through your nose the whole time your face is in the water. Empty lungs at the rotation means the inhale just happens.
The forearm should stay close to vertical, with a high elbow. When the elbow drops, you’re pushing water sideways and burning out your shoulder. The Freestyler paddle teaches this faster than any verbal cue.
Your head steers the rest of you. Look down at the bottom of the pool, not out at the wall. The moment you lift the head, your legs sink and your drag goes through the roof.
The hand should land in line with the shoulder, not across your head. When it crosses, you swim in a soft zig-zag. You’ll feel it as a wobble more than see it.
At our target pace, the kick is mostly there to stabilise. Loud, splashy kicking burns the legs and barely changes the speed. Keep it quiet and let it come from the hip.
If you go hard on a broken stroke, you just lock the broken stroke in. Get the mechanics right at a slower pace first. Speed shows up on its own once the stroke is working.
A tense neck stops you rotating, which is half the stroke. Soften the jaw, drop the shoulders, breathe. A few minutes of box breathing on land before a swim helps more than it sounds like it should.
A drill that isn’t followed by some normal swimming doesn’t transfer. After each drill block, do 50 or 100 m of regular freestyle and try to keep whatever feeling the drill just gave you. That’s where the change actually happens.
Pushing the chin forward and lifting the face out of the water to grab a breath is the single fastest way to sink your legs and waste energy. The rotation does the work, the head just goes along for the ride. Goggle on the cheekbone, one eye in the water, breathe and back down.
If you can hear your hand land on the water, the angle is wrong. The hand should enter cleanly in line with the same shoulder, fingertips first, with no splash. A wide or slapping entry wastes the catch before it even starts.
A death grip on the tool tightens the whole arm, the shoulder, and the upper back, which is the opposite of what we want. Hold a paddle just firmly enough to keep it from flying off. Hold a kickboard with relaxed hands. The forearm is the part that pulls water, not the fist.
You roll to breathe, the head comes up a bit, and the legs drop. Now you’re dragging the back half through the water for the rest of the length. Fix is two parts: rotate, don’t lift, and keep a small steady kick going through the breath instead of pausing it.
Before the session shape, the rule that matters most for beginners:
In swimming, frequency beats total time. Shorter sessions of 15 to 30 minutes done often are usually more useful than one long swim a week. Spend that shorter time on the basics and the drills.
Some conditioning matters eventually, but in swimming, technique is make-or-break. Skip the technique work and you stop progressing, full stop.
Aim for two or three sessions a week. They can be 45 to 60 minutes if you have time. The shape below works for a longer session. For a shorter one, just trim each block proportionally and keep the order.
First rule: take as long as you need at each stage. Move on when the drills feel easier, not because the calendar says so. If something still feels hard, it needs more work, not more distance.
Most of the course is done in a small pool with the Slipstream, so traditional distance sets (4 × 300 m, that kind of thing) don’t really apply the way they would in a long lane pool. Think about stage readiness instead:
Two options if you want to move faster than self-study. Neither one is required, the page stays free either way.
If you have a small home pool (or access to one), owning a Slipstream is the most convenient way to work through this course on your own schedule. The Yousuli member discount on the unit sits behind the YSC members page.
