What changes with ZWIM
Make an adjustment.
See your number respond.
The patent-pending ZWIM Smart Paddles measure force and movement while you train on land.
Adjust your catch and watch your Propulsive Watts respond immediately.
Power × efficiency
= Propulsive Watts
= Propulsive Watts
A personal dryland training metric. Compare your sessions on the same paddles over time.
What does efficiency mean?
Propulsive Watts combines your power with the share of your press directed backward. When Propulsive Watts rises faster than raw power, more of your effort is directed backward.
Train beyond the first good stroke.
Build swim-specific endurance with repeated work through the propulsion phase. Choose from three levels of Propulsion Bands.
See what changes over time.
Compare left and right. Review your session-average Propulsive Watts, power and history across your training.

The ZWIM Smart Trainer
Patent-pending Smart Paddles, the ZWIM Bench 2.0 with built-in Speed Pump, 3 Propulsion Bands. Plus the game and app.
Connected Swim Training
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.
Real data to track from week one
For the first time, your stroke has a number. Propulsive Watts combines the power and efficiency of your stroke.
A session you want to repeat
A 3rd or 4th pool session isn't realistic. This is, 10–35 minutes at home, stroke as controller, workouts and targets waiting.
Stop starting over every pool day
Keep the feel alive with two short sessions in between, and the catch is waiting the moment you hit the water.

Before you decide
Your questions, answered.
How does this fit alongside swimming?
Use ZWIM to practise the propulsion phase of your stroke and train swim-specific endurance on land. Keep swimming for breathing, body position, rotation, feel for the water and open-water skills. The two sessions have different jobs.
Will the numbers tell me my race time?
Propulsive Watts is a dryland training metric, not a prediction of pool pace or race time. Use it to compare your own work on the same paddles over time.
What space and equipment do I need?
You need room to lie on the ZWIM Bench 2.0 and extend your arms, a suitable door anchor position, and a compatible phone or tablet. Check the full setup and device requirements on the product page.
What works without membership?
The hardware works with a basic dashboard. Membership adds the ZWIM Experience, including the game and training history. Check the product page for the latest feature availability before ordering.
What happens while I wait for my pre-order?
You pay for your order now. Your membership period begins at activation. Batch 2 dispatch is estimated for 15 December 2026. You can cancel before dispatch for a full refund, including membership.
