WaterRower S4 Rowing Machine

Authentic Water Resistance. Smooth Natural Motion. The Feel of Real Rowing.

Bring the experience of rowing on open water into your home with the WaterRower S4, a handcrafted rowing machine engineered around the unique WaterFlywheel. Designed to reproduce the physical dynamics of a moving boat, the WaterFlywheel delivers smooth, self-paced resistance that responds naturally to your effort.

Unlike mechanically resisted rowers, the WaterRower doesn't force a predetermined resistance onto you—you create the work. Row harder and the flywheel moves faster; row easier and the pace naturally decreases. This intuitive resistance system makes the WaterRower suitable for a wide range of fitness levels while providing a fluid, low-impact training experience.

The S4 Monitor tracks key performance metrics and, with built-in Bluetooth connectivity, integrates with compatible indoor rowing applications. A comfortable contoured seat, smooth stroke mechanics, and integrated transport wheels complete a premium rowing experience designed for performance, comfort, and convenient home storage.

BENEFITS

The Natural Feel of Rowing on Water

Authentic Rowing Experience
The WaterFlywheel is specifically designed to replicate the physical dynamics of rowing a boat, creating a remarkably natural and immersive rowing sensation.

Resistance That Responds to You
You are the engine. The amount of work you apply determines how quickly the flywheel moves, allowing you to control the intensity naturally from a gentle paddle to an all-out effort.

Smooth, Low-Impact Movement
The water-based resistance system provides a fluid stroke without the abrupt mechanical feel, helping create a comfortable and controlled workout.

Train at Your Own Pace
Because resistance is self-regulated, you can determine your own workout intensity without preset resistance levels dictating your pace.

Encourages Consistent Technique
The WaterFlywheel promotes a smooth, even stroke that distributes work across the major muscle groups while supporting efficient rowing mechanics.

Track Your Performance
The S4 Monitor provides essential workout information, helping you monitor intensity, stroke rate, heart rate, and other training data.

Connect to Rowing Apps
Built-in Bluetooth connectivity allows compatible S4 BLE models to connect with popular indoor rowing applications for an enhanced training experience.

Comfortable for Extended Sessions
The contoured rowing seat provides cushioning and support while helping maintain a comfortable posture throughout your workout.

Easy to Move and Store
Integrated transport wheels make repositioning the rower easier, while its upright storage capability helps conserve valuable floor space.
