* 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.
As I mentioned, the rowing experience with the WaterRower is amazing. I bought the rower for myself, but my wife was curious and decided to try it out. She loves it, and now rows almost daily. We have a treadmill that neither of us has used since we started rowing - the WaterRower is a much better workout and much more enjoyable at the same time. It's easy to adjust the intensity, pace and duration of your exercise. There is nothing to change on the rower (* see note below), you just row harder or faster, adjust how far you lean forward and back during your stroke. The WaterRower will keep up with you as your fitness increases, all you need to do is keep throwing more and more at it.

Originally made from wood, shells are now almost always made from a composite material (usually a double skin of carbon-fibre reinforced plastic with a sandwich of honeycomb material) for strength and weight advantages. FISA rules specify minimum weights for each class of boat so that no individual team will gain a great advantage from the use of expensive materials or technology.
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.
This type of calorie burn is better than what you would get from cycling or running, and it’s much gentler on the body. You can also position your hands differently in order to work new muscle groups in your lower and upper arms. Many people will be surprised to learn that rowing works the legs more than any other muscle group, but by switching up your rowing position, you can also focus on your abs, arms and shoulders for a total upper body workout that can provide impressive results just by working out a few times a week.
In deep water the speed (or velocity) of a water wave depends only on its wave length. Specifically, the speed is proportional to the square root of the wavelength. Thus, the longer the wave length, the faster the wave, or vice versa. The speed of a single wave is called the phase speed. Amazingly, the speed of a packet of waves (the group speed) is often not the same.
From a fitness perspective, the WaterRower Natural works 84 percent of your muscle mass, helping tone and strengthen your muscles while burning far more calories than most other aerobic machines. The exercise is also low impact, as it removes all the body weight from the ankles, knees, and hips, but still moves the limbs and joints through a full range of motion--from completely extended to completely contracted.
