Another negative point for me is the angle of the seat. Unlike the Concept2, it has a slight backward angle, which makes it easier to maintain good form at the end of the stroke. Given that the Waterrower has greater resistance at the catch, it puts more pressure on the lower back at this point making it uncomfortable for people like myself with lumbar spine problems.

There are 4 main rowing machine types that are classed according to its utilized resistance mechanism. Having an exercise workout needs to have resistance against the movement in order to provide to the muscles and the cardiovascular system a good change. This can be provided by the rowing machine whenever you pull its handle and then slide back to the seat. Having low resistance works on the cardiovascular system can make you row fast easily. Having high resistance means that it provides you with the anaerobic session, working with the muscles harder, also having a slow stroke rate because of the harder pull.
* While there is nothing to adjust from row to row on the WaterRower, it is possible to increase or decrease the level of resistance by changing how much water you put in the drum. The monitor is pre-calibrated to match 17 liters of water, but you can change that if you want. More than 17 liters = more resistance, up to the max fill line. This is not something you'll want to change frequently, it's more of a set-it-and-forget-it thing.
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.

I loathe exercise. Will do almost anything to avoid it, like holding down a couch or going to wash a car. But the time came to find something that I could do that would get me into regular exercise and make the most of the time. After researching, I found that rowing was almost universally lauded as a great full body workout that does not abuse your joints, and requires only a minimal time commitment. After searching and researching , the Water Rower consistently came out at the top of the pile. So I spent the big bucks and ordered one.
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.
The WaterRower Natural is handcrafted from solid Ash wood, finished with a honey oak stain and danish oil. The WaterRower's patented WaterFlywheel has been specifically designed to emulate the dynamics of a boat moving though water and is unsurpassed in its simulation of the physical and physiological benefits of rowing.
