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.

Here’s a secret, because the rowing machine provides an intense full body workout, the exercise burns a high amount of calories not only during the actual activity but also for a period after you’ve stopped. This is known as the “after-burn effect”. Essentially, you’ve worked your body so hard that it is forced to keep burning calories and fat even when you’re not rowing. The scientific jargon for this is “excess post-exercise oxygen consumption” or “EPOC” for short. But all you need to know is that if you’re doing an intense rowing workout, the benefits continue after you’re done. How great is that?
In sweep or sweep-oar rowing, each rower has one oar, held with both hands. This is generally done in pairs, fours, and eights. In some regions of the world, each rower in a sweep boat is referred to either as port or starboard, depending on which side of the boat the rower's oar extends to. In other regions, the port side is referred to as stroke side, and the starboard side as bow side; this applies even if the stroke oarsman is rowing on bow side and/or the bow oarsman on stroke side.
