One of the major deciding factors between water and air rowers is price. Water rowing machines are often found in higher price ranges with the lowest model going for $700 and the best models starting around $1,100. Air rowers are found in every price range starting at $300 and going as high as $1,000+. The affordability of air rowing machines makes them very popular.
John Duke, creator of the WaterRower, was inspired to try his hand at invention while working at a subsidiary for U.S. Steel. He wanted to make an indoor machine that felt as much like real rowing as possible, with a focus on aesthetics. It took him two years to get the design right, moving past failed ideas such as a flipper in the tank instead of a clutch. What began as a series of doodles at his desk turned into a sculptural piece of exercise equipment that upends expectations in two ways: by bringing water indoors, and by looking elegant and artful when stored.

A 125-pound person moving at an average pace for 30 minutes on a treadmill will burn roughly 250 calories. However, they aren’t able to take advantage of this after-burn effect. The same person rowing vigorously will burn around to 250 calories but will have less stress placed upon their joints and continue to burn calories after the workout has ended. Rowing machines have been shown to burn on average 800 calories an hour if you work harder and are slightly heavier.

Water rowers feature a tank that is actually filled with water as a means for resistance. As you increase the pace of rowing, the resistance naturally increases as well. This means that you can set your own pace and resistance in a single motion. The same is true for air rowers. Air rowers use a fan or flywheel to create resistance, and you have control over the intensity of the workout due to the fact that the air resistance depends on your pace. Most water and air rowers come equipped with -- or at least have as an option -- monitors that track various functions such as distance, strokes, strokes per minute and calories burned.
The WaterRower Natural is handcrafted in solid ash and stained honey oak for consistency of color. The wood was chosen due to its marvelous engineering properties, especially its ability to absorb sound and vibration, which enhances the WaterRower's quiet performance and smooth operation. Ash, like all woods used in the construction of the WaterRower, is a premium hardwood with incredible longevity and dimensional stability. In addition, the wood is harvested from replenishable forests and is hand finished with Danish oil to provide a deep luster.
