Invented by Yale University engineer and USA Rowing National Team candidate John Duke in 1988, the WaterRower has been hand-built in North America from fine Appalachian hard woods for nearly 35 years. The enduring appeal of this machine comes thanks to its impeccable marriage of form and function; harnessing water resistance to replicate the sensory experience and many physiological benefits of real rowing, packaged in a beautifully minimal design.

Now it’s possible to further upgrade the experience of the award winning WaterRower by pairing it with asensei, the app that makes rowing better, giving you structured & personalized workouts and coaching. asensei features hundreds of diverse, fun and educational workouts and structured programs from Olympic Champions like Eric Murray, British Rowing Master Trainer Clare Holman and studio fitness legend Johan Quie.

Why choose the WaterRower?

The full-body nature of working out on the WaterRower makes it one of the most effective workouts you can do, whether for burning fat, toning muscle or improving cardiac health. The benefits are felt from head to toe, with every stroke seeing almost 85% of the bodies total muscle mass recruited. The smooth, self regulating resistance generated by the water flywheel is easy on the back and creates zero impact on joints. It’s also nearly silent in use, producing nothing more than a satisfying whoosh as you drive water around the tank.

When not in use, your WaterRower can be just as pleasing, and easy, to live with. Hand built from a range of sustainably sourced timbers grown in the North American Appalachian Mountain ranges, the machine is beautifully designed with a timeless, minimal scandinavian style. Available in a selection of finishes to suit your interior, you can also easily stand the machine upright, where it will take up about as much space as a dining room chair when you aren’t using it.

Pairing with asensei allows you to enjoy world class workouts on one of the finest rowing machines, all from your own home.

Why choose asensei?

Pairing your WaterRower with asensei delivers a world of high quality, carefully guided training to the comfort of your own home. Train alongside world class athletes and follow personalised training plans to fully unlock the many fitness benefits of your WaterRower.
