According to fitness experts, water resistance is by far the most efficient technology used in a rowing machine, and the result is a realistic rowing experience that provides a better workout with smoother and more fluid rowing. These machines use a paddle that’s suspended in a tank of water, providing a realistic sensation of rowing outdoors. Extremely quiet running, as you row the only sound you’ll hear is the gentle splashing of water moving with each stroke, which serves to enhance the realistic experience of this style of rower.
The overall rowing experience encompasses pulley, seat, and — of course — resistance. Air and water have very distinct qualities, making them impossible to compare but interesting to contrast. Air stores inertia, which feeds into intense, constant effort during a goal-oriented workout. Water’s more sluggish drag makes for demanding exercise, but one that’s less consistent.
The rowing machine itself is unlike any other on the market with its patented water filled flywheel. It is hard to exactly copy the action of a scull on the water, but the mechanics of the flywheel spinning in water comes in a close second on dry land. The fact that the water is 800 times denser than air means that there is no need for any extra resistance or dampening that you will find in normal air rowers. The faster you pull, the more resistance is generated giving it infinite variability. However, if you want to be able to practice rowing with a faster stroke, you will have to reduce the amount of water in the tank unlike an air rower where you just have to adjust the baffle.
