Sunny vs WaterRower Rower Specs
Resistance type
The Sunny Health & Fitness P2100 uses three built-in resistance bands to provide up to 66 lbs of total resistance. You can scale your intensity from beginner to advanced levels by adjusting these bands. The WaterRower Walnut S4 uses a water-filled flywheel for resistance. This creates a smooth, natural feel that mimics rowing on actual water. The harder you pull, the more resistance you generate. Water resistance is self-regulating and changes with your effort, while band resistance is fixed at three levels. If you prefer adjustable mechanical tension, the Sunny model offers that. If you want a fluid, dynamic experience, the WaterRower is the clear choice.
Weight capacity
