WaterRower For over 20 years, WaterRower has been providing the world with rowing machines that demonstrate the physical and physi...ological benefits of rowing. Rowing is a complete aerobic exercise routine that works 84 percent of muscle mass and gives maximum results - you burn more calories in less time and have fun, too. Rowing combines aerobic exercise with resistance all in a smooth, rhythmic exercise. It's suitable for people of all shapes and sizes and is easy on the joints.WaterRower is committed to being environmentally conscious. Their rowing machines are made using only the world's finest hardwoods specially selected from replenishable sources where more wood is planted than harvested. Because WaterRower machines are people- powered, no electricity is required! WaterRower rowing machines help you burn calories, tone muscles, and be kind to the environment. read more

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.

Rowing machines were first used in Archaic Greece. Chabrias, an Athenian military general in 4th Century B.C., invented wooden rowing simulators for his inexperienced oarsmen. This enabled them to learn technique and timing before stepping foot on actual water crafts. And it must have worked — Chabrias successfully led numerous naval attacks against the Spartans.
The WaterRower Natural is outfitted with a Series 4 performance monitor that's designed to balance technical sophistication with user-friendliness. The monitor--which includes six information and programming windows, six QuickSelection buttons, and three navigation buttons--displays your workout intensity, stroke rate, heart rate, zone bar, duration, and distance. Plus, the monitor is compatible with an optional heart rate chest strap and receiver, which helps you optimize your workout and achieve your exercise objectives.

The WaterRower Classic Rower has been designed to optimize ease of storage. Simply lift one end and the machine stores conveniently upright in about the space of a dining room chair. The WaterRower Classic Rower has a light wooden frame, the positioning of the WaterFlywheel close to the wheels, and the leverage effect provided by the rails, makes lifting almost effortless. When stored the WaterRower's patented WaterFlywheel provides a low center of gravity making the machine very stable.
Rowing is a cyclic (or intermittent) form of propulsion such that in the quasi-steady state the motion of the system (the system comprising the rower, the oars, and the boat), is repeated regularly. In order to maintain the steady-state propulsion of the system without either accelerating or decelerating the system, the sum of all the external forces on the system, averaged over the cycle, must be zero. Thus, the average drag (retarding) force on the system must equal the average propulsion force on the system. The drag forces consist of aerodynamic drag on the superstructure of the system (components of the boat situated above the waterline), as well as the hydrodynamic drag on the submerged portion of the system. The propulsion forces are the forward reaction of the water on the oars while in the water. Note also that the oar can be used to provide a drag force (a force acting against the forward motion) when the system is brought to rest.
The first international women's races were the 1954 European Rowing Championships.[54] The introduction of women's rowing at the 1976 Summer Olympics in Montreal increased the growth of women's rowing because it created the incentive for national rowing federations to support women's events. Rowing at the 2012 Summer Olympics in London included six events for women compared with eight for men.[55] In the US, rowing is an NCAA sport for women but not for men;[56] though it is one of the country's oldest collegiate sports, the difference is in large part due to the requirements of Title IX.

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.
