ZWIM Smart Trainer
For triathletes who are done with “just surviving the swim”.
The swim gets better with reps. ZWIM gives you the extra reps between pool days — 15 minutes at home, real resistance, live feedback on your stroke. No pool hours to work around.
That did not go through. Please try again, or email hello@zwim.com and we will sort it.
YOUR PACE ISN'T MOVING, AND IT'S NOT FOR LACK OF EFFORT
Getting faster in the water comes down to frequency, and frequency means more pool time. But how do you fit another session in when your week has no slots left? That's the problem ZWIM was built to solve.
Swimming faster takes skill and swim-specific endurance, and both come from repeating the movement.
The feel you built fades between pool days, and every session is spent starting over. The pace sits still. The progress stalls.
ZWIM trains propulsion, the phase of your stroke that generates speed. Now the feel doesn't fade. 15 minutes at home, 2 to 3 times a week, and owners of our first trainer were 7.4× more likely to feel faster (self-reported). You feel the difference from the first session; strength builds over 4 to 8 weeks.
No drive, no lane, no wet kit in the car. Just ZWIM at home between pool days. You arrive at your pool sessions switched on. And the pace that sat still, starts to move.
Your stroke is the controller.
Never-before-seen live data on your stroke, the moment you make each pull. ZWIM shows you what's working as it happens, and turns it into a game.
THE POOL GIVES YOU A PACE AT THE END. ZWIM GIVES YOU POWER, EFFICIENCY AND BALANCE ON EVERY PULL.
“ZWIM BENCH 2.0. MUCH MORE STABLE. MUCH BETTER.”

7.4× more likely to feel faster
Swimmers who trained 9+ times a month between pool days: 61% felt faster in the water. Among those who did none, it was 8%.
Dryland swim training works. But HABIT WAS HARD. ZWIM changes everything.
Look at that data again. Train about twice a week between pool days and you were 7.4× more likely to feel faster. Almost nobody got near that. That is not a kit problem. Dryland training on its own gives you no reason to come back. That is what we set out to fix with ZWIM.
Set it up. Work out what to do. Do it with no feedback. Have no idea if it worked. Then find the will to do it all again on Thursday.
It asks for motivation it does nothing to supply.
Your pool days stay exactly where they are.
The pool is where you swim. ZWIM takes the days in between, the ones that were never going to be pool days anyway. No drive, no lane, no second shower. Up in 60 seconds, training in 3 minutes. 10 to 35 minutes, at home. Use it to start your day, before the bike, or during your lunch break.
Up in 60 seconds. Training in three minutes.
No tools. No drilling. No spare room. If you can lie down with your arms out, you have enough space.
The first hundred are built by hand. Not prototypes.
We're in production as you read this. Each of the first hundred units is assembled by hand, calibrated, and checked before it's packed in the box.
These are not alpha units and they are not beta units. They are the final product. You are early, not a test subject.
What is live, what is close, what is on the roadmap.
You are paying up front, so you should know exactly what you are getting on day one and what you are betting on. Here it is, with nothing hidden in a footnote.
Tell us what is working and what is not, and it changes. Fast. The routes, the sessions, the numbers on screen — the first hundred shape all of it, and we will keep asking.
The more ZWIMMERS training, the sooner live racing and group sessions land. You are not buying a finished product. You are getting in early enough to decide what it becomes.
Where we ship, and what it costs.
Train on it for a month. If it’s not for you, send it back.
You get a full refund for the ZWIM Smart Trainer and your membership. No questions asked.
The details.
The questions you are actually asking.
Technique needs repetition to hold. It cannot survive days of nothing. 4 days off and the movement dulls. That is why the start of a swim feels like starting over. ZWIM keeps the pull alive between pool days, so you arrive switched on. Research with CIDESD is underway. We part-fund it, and we will not claim proven transfer until it lands.
£349 for the trainer, plus your first membership. On annual that is £99, so £448 today, with free shipping. You get 15 months for the price of 12. Your membership clock starts when you activate the trainer, not today. You pay nothing for the wait.
The first 100 trainers ship by the end of November 2026. The next batch ships by the end of 2026. If a date moves, we email you. You can take a full refund at any point before yours ships.
Then you have lost nothing. Change your mind before it ships and you get everything back, hardware and membership together. Once it arrives you get 30 days to train on it. Not look at it. Train on it. Sweat on it. If it is not for you, send it back and we refund all of it, membership included. The only thing you can lose here is the time you spend trying it.
Yes. The trainer is yours to keep and it works. Membership is what makes it connected. That is the game, the workouts, the live numbers and your history.
We train the propulsion phase, which is where propulsion comes from, and we do not simulate the rest of the stroke. Breathing is actually freer on the bench, so you can hold form longer than you can in the water. Kick and rotation stay pool work, and ZWIM is what stops your pool time being spent rebuilding a catch that faded since last week.
Not yet. The team is building it now and we intend to have it live before the first trainers ship. If it is not on Strava it never happened, and we would like your ZWIMs to have happened.
Today you get leaderboards and ghost players, so you are racing real times rather than an empty world. Live multiplayer racing and group sessions are on the roadmap without a date. The faster the community grows, the faster we can fund it.
Enough floor to lie down with your arms out, and a door or a solid fixture to anchor to. The bench is 35 by 45 by 80 centimetres. Nothing gets drilled into a wall.
The bench is up in about 30 seconds using the built-in Speed Pump. Paddles connected and training in under 3 minutes from cold.
No, and we would not want it to. The pool is where you swim. ZWIM is for the days a pool session was never going to happen.
Any smartphone or tablet running iOS 16 or Android 12 or newer.
You’ve spent years “just surviving” the swim. That ends now.
Everything in the box is yours to keep. 15 months of The ZWIM Experience for the price of 12, locked at £99 while you stay annual. ZWIM Goggles and cap for the first hundred.
