On a rowing machine, you don’t want to be wearing clothes that are too baggy as the fabric can get caught between the seat and the beam it slides on.  It’s not a disaster if that happens, but it can get annoying if your shorts keep getting caught there while you’re trying to get a serious workout.   It’s better to wear shorter, tighter-fitting shorts (nothing ridiculous), but just enough to ensure it doesn’t the material doesn’t hang down.
The advantages with air rowers is that there is smooth action; there is only small wear and tear to its mechanism; its automatic feature adjusts according to your rate of strokes; and there is a wide range of the resistance readily available in replicating the feel of rowing through the waters. The only disadvantage of this machine is that it tends to be noise indoors.
There are various air rower or water rower techniques, but the most basic one is by starting at the back stroke, the knees should almost be completely straight prior to squeezing the shoulder blades together. Then you pull its handle to the sternum. The back of your body should naturally stay in its arched position when doing the whole movement. Do not forget to take a record of the distance you have made after every session. Some people even take it as far as uploading their results online and see how they are ranked from other people who are also doing the same. You clean learn more about rowing machine technique on this page.

If you're looking at a WaterRower, you're probably also considering the Concept2. They're both great machines, but which you choose depends on your needs. I think the WaterRower is ideal for most people, but not everyone. The WaterRower has a number of advantages vs the Concept 2 - it is quieter, the mechanism up front is lower profile, it has a comfortable seat, it is much better looking, it's easier to stand up when you're not rowing and it's just ... zen-like. There is something about the smoothness of the WaterRower that makes it a joy to use, and because it's quiet you can easily stream your favorite binge-series without cranking the volume too high.
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?
The WaterRower Club is hand crafted in solid Ash and stained for color. The WaterRower Club has been designed for High Traffic Areas such as Commercial Gyms, Studios, Rehabilitation Clinics, etc. Its Black Rails have been styled to prevent scuffing, other wooden components are finished in an attractive rosewood which are more resistant to soiling than the Natural model. Each machine has been hand finished with Danish Oil and Urethane for protection. Wood has been chosen due to its marvellous engineering properties, primary amongst these is its ability to absorb sound and vibration enhancing the WaterRower's quietness and smoothness of use. Ash, like all woods used in WaterRower construction, is a premium hardwood with incredible longevity and dimensional stability. s For reasons of ecology, all our woods are harvested from replenishable forests.
The model E’s seat stands 6 inches higher. And while the model D’s monitor rests on an adjustable arm, the E’s sits on unbending metal. These few technical differences do nothing to impact ride feel. We recommend the $200-cheaper model D as the best buy, but the Concept 2 E will appeal to anyone who values a higher seat and more solid construction.
If you’re interested in using a rowing machine for focused training — whether for outdoor rowing, an indoor competition, or as part of a larger fitness program — you’ll want air resistance. If you’re drawn to rowers for the enjoyability (alongside the full-body, cardio-plus-strength training efficacy) of a rowing workout, consider a machine with water resistance.

Rowing has long been recognized as the perfect aerobic pursuit, with naturally smooth and flowing movements that don't tax the joints but do boost the heart rate. Now you can take your rowing experience to the next level with the commercial-quality WaterRower Club rowing machine. Using the same principles that govern the dynamics of a boat in water, the WaterRower Club is outfitted with a "water flywheel" that consists of two paddles in an enclosed tank of water that provide smooth, quiet resistance, just like the paddles in an actual body of water. As a result, the machine has no moving parts that can wear out over time (even the recoil belt and pulleys don't require lubricating or maintaining). More significantly, the water tank and flywheel create a self-regulating resistance system that eliminates the need for a motor. As with real rowing, when you paddle faster, the increased drag provides more resistance. When you paddle slower, the resistance is less intense. The only limit to how fast you can row is your strength and your ability to overcome drag. And unlike conventional rowing machines, which tend to be jerky and jarring, the WaterRower Club is remarkably smooth and fluid.

If you’re on the hunt for a rowing machine for home fitness, keep in mind that there are many different styles and features that you’re going to want to consider before choosing. As always, high quality comes with a price, but there are great, reliable rowers at lower prices as well. We’ll do our best to break down all the things you need to know below.  And we have included our top rower picks to help you find the best rowing machine for your needs.

The Water Rower comes partly preassembled in two large boxes. The assembly instructions are reasonably good, and as long as you take your time and follow them carefully (read all the text) it takes about 45 minutes from opening the first box to trying it out. I bought bottles of distilled water to fill it, which made it easy to fill using the included funnel & hose.
